Scientists tweak wireless power transfer, Tesla nods happily in his grave

Steve Dent — Wed, 16 May 2012 11:14:00 EST

Wireless charging may be all the rage these days, but actually beaming electricity -- as sketched above by the man Tesla himself -- still has some snags. North Carolina State U researchers have found a way to possibly vanquish the biggest problem: the difficulty of exactly matching resonant frequencies to amplify current. If external factors like temperature change the tuning of a transmitter even slightly then power drops will occur, but circuitry developed by the NC State scientists would allow receivers to detect these changes and automatically re-tune themselves to match. This could make for more potent car and device charging in the future and, if they stretch the distances a bit, maybe we'll finally get the wire-free utopia Nikola dreamed up 120 years ago.

Sony applies for wireless power patent, wants to daisy-chain your energy

Jon Fingas — Tue, 15 May 2012 21:05:00 EST

As much as we're familiar with wireless power, we know developing a truly contact-free form of charging has a whole raft of extra challenges, such as getting into the sweet spot for power delivery and the potential traffic jam caused by throwing another device into the mix. Sony thinks it has these problems licked through a newly-published patent application. Its method uses location-finding to steer users until they're close enough for the wireless power source to reliably do its job. In some cases, it can use one mobile device to relay power to another, keeping everything fed even if the main power hub is tied up. Multiple power sources next to each other can go so far as to decide which of them should be the one to send power. The patent isn't a certain sign that your VAIO or Xperia is about to cut the cord altogether -- Sony first submitted this vision of the future in 2009. Even so, it gives us hope that our gadgets will one day start charging themselves instead of making us hunt down a wire or charging plate.

Samsung, Qualcomm start up Alliance for Wireless Power to take on Qi

Jon Fingas — Tue, 08 May 2012 04:22:00 EST

Wireless power has until now been closely associated with the Wireless Power Consortium's Qi standard. There's now a second proposed common ground in the Alliance for Wireless Power, or A4WP. Samsung and Qualcomm, along with some help from Powermat, SK Telecom, Ever Win Industries, Gill Industries and Peiker Acustic, are making an alternative that allows for "spatial freedom" between your gadget and the charging source, although whether or not that's better than the 1.6-inch distance of the updated Qi spec is left to the imagination. The strategy doesn't just let your device avoid French kissing the charger: it lets you power up through a material besides a metal plate, and it reduces the cost by eliminating repeaters. A4WP should power everything from low-power headsets through to smartphones and tablets, although with partnership talk just getting started at CTIA Wireless 2012, we wouldn't hold off on buying wired-power gadgets in the near future.

Duracell Powermat WiCC could bring wireless charging to any smartphone, we go hands-on (video)

Zach Honig — Sun, 26 Feb 2012 09:30:00 EST

Powermat may have a bright future, but the company's products to date have been expensive, slightly clunky and a generally imperfect solution for bringing wireless power to mobile devices. That could all change with WiCC. The Wireless Charging Card (WiCC) is an IEEE Power Matters Alliance (PMA) standard, with the potential to integrate Duracell Powermat technology within every mobile gadget. The incredibly thin device resembles those wafer-like SmartMedia cards once used in early digital cameras, with a similar form factor, but significantly more practicality. Each WiCC includes all the PowerMat circuitry found in the company's charging cases, while also doubling as an NFC antenna. The card's success is of course contingent on cooperation from device manufacturers, who will need to add a slim connector above the battery leads, including two for power, two for NFC and two for data -- an app will monitor charging. Powermat reps say that such a connector would cost pennies to implement, however, making it a potentially easy sell.

Powermat President Daniel Schreiber sees this as a major breakthrough for the smartphone industry, saying "we're going to do for wireless power what the memory card did for storage in mobile phones." We had a chance to take a look at a mock-up of the wireless card at MWC, which was resting just above the battery in a Samsung Galaxy S II. Because the phone's battery is slightly recessed, both the card and battery fit below the device's original backplate -- the WiCC lies flush with the phone's camera lens. Overall, we think there's some serious potential here, assuming device manufacturers are game to come on board. Still, don't expect to see these hitting stores anytime this year -- the company expects its other products to come to market long before the Wireless Charging Card. So for now, jump past the break to take a closer look, but don't make any plans to toss that power adapter just yet.

Nissan Leaf to get inductive charging, lose its stem in 2013 (video)

Zach Honig — Mon, 05 Dec 2011 20:30:00 EST

Nissan has big plans for the still-budding Leaf. The Japanese automaker lit up its impressive Leaf-powered Smart House at the Tokyo Motor Show last week, but also demoed its wireless charging solution for a much smaller crowd at the company's Oppama factory. The device uses electromagnetic induction to transfer power between a charging pad and a receiver on the bottom of the car, with an efficiency level between 80 and 90 percent -- simply park your EV directly above the system to begin charging, and monitor progress on the ground transmission unit's control panel. The pad is expected to become available as soon as 2013, but will only be compatible with new vehicles, so you won't be able to use it with an older Leaf, unfortunately. There's a silent demo video waiting for you just past the break.

Rohm Wireless Power Transmission system hands-on (video)

Zach Honig — Thu, 06 Oct 2011 09:42:00 EST

Wireless power demos abound at CEATEC, and Rohm Semiconductor had their own variant on hand with a complete mix of direct-draw gadgets, along with the omnipresent charging iPhone 4 (or was it a 4S?). Like Murata's prototype, the Rohm flavor uses square electrodes instead of the coils that you'll find in traditional wireless power solutions, like Qi. But unlike that seemingly identical solution from Murata, this version supports much greater power efficiency -- something in the 92 to 93 percent range (compared to the competing pad's 70-percent efficiency rating). That means that the prototype that we're looking at here loses just seven to eight percent of power during transmission -- which is still unacceptably high, mind you, but far more tolerable. Rohm's Wireless Power Transmission system also allows you to charge or power devices by placing them anywhere on the pad, rather than directly over charging positions, and it supports much greater transmission, with one prototype outputting up to 100 watts.

Since power efficiency isn't something we could verify visually, what we could see at the company's demo did appear to work quite well. Powering a gadget is as simple as dropping it on the pad. Well, resting it gently -- this is a prototype we're talking about, after all. The 50-watt pad was able to power a fan, LED light, and a couple of charging smartphones without issue. The light and fan jumped to full power as soon as they made contact. A second pad got the juices flowing to a large OLED light panel, which was plenty bright when positioned on its own pad, but glowed quite dim when joining other devices. There weren't any charging laptops on hand, like we saw over at Murata, but with power output at 50 and 100 watts, either pad could theoretically support it. Like many of the prototypes we've seen at CEATEC, there aren't any plans to actually bring the system to market, but the technology could be used in other devices. We go hands-on after the break.

Murata Wireless Power Transmission System supports laptops, we go hands-on (video)

Zach Honig — Wed, 05 Oct 2011 07:33:00 EST

Do we really need another wireless charging system that's incompatible with industry standards? Murata seems to think that we do. The company's prototype uses neither conductive nor inductive transmission, instead bringing its new capacitive coupling technology to the cordless charging mix. Capacitive coupling uses square transmitter and receiver electrodes, instead of the coils used with Qi devices. It also doesn't require a physical connection like near-obsolete conductive tech, which dictates that both the charging pad and receiving device use metal connectors that must be joined to transfer current. The Murata system is far from being production-ready, with only 70 percent efficiency (30 percent of electricity is lost during transmission). The sample the company had on hand can support 16 watts of output with a maximum of 2.1 amps, making each pad capable of charging several small gadgets, or one larger device, like a laptop.

Murata seemed more interested in demonstrating the concept behind capacitive coupling than actually proving that it works -- the laptop we saw "charging" was a plastic mockup, though the base did glow red when the laptop's charging pad came into contact (though it also glowed blue at times, as you can see in the image above). We did take a close look at an iPhone case, however, which appeared to be remarkably thin -- much thinner than models from Powermat, for example, though the case does extend below the dock connector. Another advantage of the square electrodes is that you don't need to place devices in a certain position on the mat in order for them to charge -- they simply need to be positioned within the general charging area. We take a closer look in the video after the break.

Evatran's Plugless Power wireless EV charger gets smaller, conscripts Chevy Volts for testing

Sean Buckley — Mon, 01 Aug 2011 23:57:00 EST

When it comes to technology, the old adage of "bigger is better" died a long time ago, so it's not a surprise to see "smaller is smarter" thinking apply to products and prototypes across the board. Today's (relatively) tiny wonder is Evatran's Plugless Power electric vehicle charging system: now smaller, more efficient, and primed for its first trial phase. The last time we saw Plugless Power, the system's wireless charging "station block" stretched nearly the length of a full vehicle and charged at 80 percent efficiency. Today the charge block is only slightly larger than an average hubcap, boasts a 97 percent charging efficiency, and is less picky about your car missing the wireless charger's "sweet spot." Evatran is now working on launching a test fleet of up to 12 Chevy Volts to put the system through its paces, and hopes to expand the tests to as many as 30 vehicles by January. Ready to ditch pumps and plugs forever? Start saving: a complete Plugless Power system (including vehicle retrofitting) will set you back as much as $5000 after production starts sometime in 2012. Don't be too surprised, cool stuff rarely comes cheap -- besides, that old adage has to apply to something, doesn't it?

Wireless Power Consortium launches Qi certification lab, cuts power cords for approved devices

Michael Gorman — Mon, 01 Aug 2011 19:43:00 EST

The power of Qi has grown and grown since the wireless charging standard was finalized. With cord cutting becoming more desirable -- and dare we say, de rigeur, for many mobile devices -- the Wireless Power Consortium (WPC) has launched an independent lab to certify gadgets wanting on its induction charging bandwagon. TÜV Rheinland's providing the speedy certification services at its Taiwanese testing facility, so we should see the legion of Qi-powered devices continue to grow at an ever-increasing rate. Guess Power Matt made the right move joining the WPC superfriends. Qi's up, cords down, playa.

uBeam wireless power startup shows prototype at D9 (video hands-on)

Darren Murph — Wed, 01 Jun 2011 08:00:00 EST

As seems to be the case each year, one or two stars show up to demonstrate new technology here at the All Things D 'Science Fair,' and it just so happens that a pair from the University of Pennsylvania are soaking up the limelight this go 'round. uBeam's the company, and based on what we saw at D9, we're guessing that you'll be hearing an awful lot more from the duo in the coming months. The company's mission is to provide wireless power -- hardly a new concept, but it's all sorts of refreshing to see what's often thought of as a pipe dream get an injection of reality. The outfit is literally comprised of two people for the moment, with the prototype shown here concocted just a few weeks ago.

The goal? To get uBeam transmitters installed in as many locales as possible, and then to hit critical mass from a device standpoint. Imagine walking into a restaurant with uBeam transmitters in the ceiling, and watching your handset magically recharge as you await your appetizer. Granted, the outfit's a long way from that -- its first product will be a small charging puck that'll connect to a bevy of USB devices. That'll pair with an enterprise or consumer-level transmitter, a device that will ideally be situated in a ceiling. For now, things are strictly line-of-sight, but the shipping system will be able to detect a uBeam puck in the room and charge it if it's anywhere within a 20 to 30 foot radius. We're told that the consumer version will be suitable for piping power to just a handful of devices, whereas the enterprise build will be able to juice up an undisclosed amount more. Care to learn more? Head on past the break.

Power Matt joins the Wireless Power Consortium, gains the power of Qi

Michael Gorman — Sat, 14 May 2011 16:06:00 EST

Powermat's Power Matt proclaimed his cord-cutting capabilities to the people while bearing a striking resemblance to Superman. And now, just as the Kryptonian joined the Justice League, Power Matt has teamed up with the Wireless Power Consortium to benefit all mankind -- or at least get us closer to universal contactless chargers. With the pun-loving hero embracing the power of Qi, we're just a Touchstone away from induction charging nirvana... and the next great action flick, too.

TI aims to bring wireless charging to more devices with smallest receiver chip to date

Donald Melanson — Mon, 18 Apr 2011 17:12:00 EST

Well, it looks like we could be about to see wireless charging spread to more places than ever before -- Texas Instruments just unveiled its next-generation, Qi-compliant wireless power receiver chip today, which is a full eighty percent smaller than its previous chip. That promises to make it far easier for manufacturers to implement in everything from cellphones to game consoles to digital cameras, and that small size apparently comes without any compromises, with it providing 5W of output power and a 93-percent peak efficiency that's comparable to an AC adapter. Unfortunately, there's no indication as to when we might see any actual devices that use the chip, but those should be coming before too long -- the complete bq51013 wireless power package is now already available for just $3.50 in quantities of 1,000. Full press release is after the break.

Google HQ gets juiced with Plugless Power EV charging unit

Christopher Trout — Wed, 23 Mar 2011 18:13:00 EST

We've seen it adorned with a giant Honeycomb and an oversized Gingerbread man, and now Google's bringing a more practical addition to its Mountain View campus -- specifically, a Plugless Power EV charging station. Its maker touts the installation as "the first public release" of the handsfree re-juicing system, and says it will eventually provided power to a fleet of low-speed EVs already in use at El Goog HQ -- the first of which has already been retrofitted to get pumped up. Who knows, maybe now we'll see something come of Google's claims to make electrical vehicles charge more efficiently. Full PR after the break.

Panasonic shows off solar-powered wireless charging table

Donald Melanson — Sat, 12 Mar 2011 11:38:00 EST

Why settle for a simple solar-powered table when you can have a table that's solar-powered and a wireless charger? While you can't get one just yet, Panasonic will apparently be selling this stylish bit of tech-laden furniture by the end of this year or early next year (in Japan, at least), which will let you charge your Qi-compliant devices simply by placing them on the table. It'll also be supplying the requisite battery packs for some of its phones at the same time, though there's few other specifics to be had at the moment. Of course, even if it does actually hit the market it'll still no doubt be out or reach for most -- there is always the DIY route for particularly industrious individuals out there, though.

Powermat's 2011 product roadmap: colorful iPhone cases, extended batteries, and more

Chris Ziegler — Thu, 13 Jan 2011 21:32:00 EST

Much of this stuff was shown off publicly for the first time at CES last week, but we thought it might be interesting to get everything that wireless charging company Powermat has planned for 2011 into one convenient place -- and that's exactly what this here slide deck has done for us. The first products in the pipeline for this year include a charging case for the Nokia N8, targeted for early Q2, along with a two-device portable charging mat that includes a built-in battery (7,800mAh!) that promises up to four full smartphone charges while staying completely off the grid; look for those to run $40 and $130, respectively. Later in the quarter, you'll get a white two-unit mat (all of Powermat's gear is black right now, so it's a nice change of pace), several colored iPhone 4 cases, a BlackBerry Torch case, and an $80 so-called Power! Case for the iPhone 4 that integrates an external 1,800mAh battery for extra juice on the go.

Moving on to the third quarter of the year, you'll see a dual-power one-device mat that can be powered either from the wall or a USB port for $40, a car mount that inductively charges your Powermat-enabled device, and an iPod touch case. Finally, the 1X Rechargeable Mat comes late in Q3, packing some undetermined (or at least unlisted) amount of juice into a mat that looks roughly similar to the existing one-device mat that's already on the market; like Powermat's other battery-powered mats, this one lets you juice devices when you're not near an outlet, and it'll be available for $70. Hit up the gallery for the full deck!

Texas Instruments ups the wireless power game with industry's first Qi dev kit

Richard Lai — Wed, 05 Jan 2011 16:22:00 EST

We have yet to see a flood of Qi-enabled devices at CES, but here's a little something from Texas Instruments that will hopefully boost the number of products supporting this newfangled wireless charging standard. What we're looking at is the bqTESLA, the industry's first Qi-certified wireless power development kit that consists of a single-channel transmitter (presumably the transparent pad with a copper coil underneath), a direct-charge receiver (the black object) and "associated magnetics for applications requiring five watts of power or less" such as cellphones, MP3 players, cameras, etc. Interested techies can pick up one of these toys for $499, or for just $250 throughout CES 2011.

Aska Electron promises to add data transfer to wireless power systems

Donald Melanson — Tue, 02 Nov 2010 12:24:00 EST

Try to get past the mess of wires in the prototype above for a minute; you might just be looking at the future of wireless power -- at least if the folks at Aska Electron have their way, that is. They've developed a new system that not only wirelessly charges your gadgets (a la Powermat and others), but wirelessly transfers data at the same time at speeds up to 120Mbps. While complete details on how that's possible are still a bit light, the system does apparently use the same coils for both charging and data transfer, but different wavebands for each. The real kicker, however, is that while it's seemingly still just in the prototype stage, Aska says it expects the first commercial applications to hit the market by the end of this year. Exactly what those products might be isn't clear, but Aska says the technology could eventually lead to thinner, waterproof devices that don't need ports of any kind.

Energizer Qi wireless charging base station spotted in the wild

Darren Murph — Sat, 30 Oct 2010 06:29:00 EST

It's taken quite awhile to go from christening to shipping, but Qi looks just about ready to make its mark on the public. And on Powermat's bottom line. We've known all along that Energizer was a huge proponent of the protocol, and now we're finding that review units are making their way out to the media. YouTube user akaTRENT seems to have gotten his earlier than most, and he's been so kind as to offer up an unboxing of the inductive charging station as well as a sleeve for the iPhone 4. We're planning on giving this same setup a whirl in due time, but if you're interested to see how this guy looks in the flesh, there's a play button with your name on it just beyond the break.

Powercast and Microchip fire up interest at a distance with wireless power development kit

Sean Hollister — Wed, 27 Oct 2010 09:39:00 EST

We're sure if you asked Powercast nicely it'd tell you a whale of a tale, about how the "more than 100 companies" who allegedly signed up to develop products that seemingly pull energy from the ether materialized into this light-up Christmas tree. Still, we'd be happy to forgive and forget if meaningful products emerged instead, and that's why we're moderately happy the company's announced a nice big development kit. $1,250 buys your firm or deep-pocketed hobbyist the spread pictured above, with a wireless transmitter to throw three watts and a pair of receiver boards to catch them from over 40 feet away, plus a low-power development board from Microchip equipped with that company's proprietary short-range wireless protocols and ZigBee functionality. We can't wait to see what people build, but we won't be snapping one up ourselves -- we're still holding out for the firm to go open-source and build an Arduino version. PR after the break.

Fujitsu says new wireless, contact-less charging system could hit products by 2012

Donald Melanson — Tue, 14 Sep 2010 16:39:00 EST

There may be an increasing number of wireless charging devices available these days, but actual contact-less charging systems have so far been confined to experiments and slightly disconcerting demonstrations. It looks like Fujitsu could be set to change that, however -- the company has just announced that it will unveil a new system later this week that can charge several gadgets simultaneously over a distance of "several centimeters," and it says that it could hit cellphones and other products as soon as 2012. That system is apparently based on magnetic resonance technology, which Fujitsu notes can in theory work over distances as great as "several meters," although the efficiency is greatly diminished -- it reportedly has an efficiency of 85 percent at 15 centimeters. Details are otherwise still a bit light at the moment (including word of any actual products), but you can be sure we'll be keeping a close eye on this one.

Global Qi wireless power standard released, Energizer and Sanyo announce products

Tim Stevens — Fri, 03 Sep 2010 10:02:00 EST

It's no good buying an eCoupled inductive charger if it won't work with your Powermat, or your Touchstone. Non-standard chargers suck, so we're glad to see that the Global Qi wireless power standard has been released, and the first products have been announced. A number of companies, Nokia and RIM to name but a few, have signed on their support, with Energizer stepping up first with the Energizer Inductive Charger. When it releases this fall it will initially work with charging sleeves for the iPhone 3G/S and BlackBerry Curve 8900, but we presume others will be coming. More promising is Sanyo, which is designing battery packs "without making any change in designs and aspects of existing mobile devices." In other words: they'll look and act like a normal battery pack, but also be able to be charged wirelessly. Beware, ubiquitous micro-USB charger: your days are numbered.

Evatran's Plugless Power gives your wheels a wireless proximity-based charge

Sean Hollister — Wed, 28 Jul 2010 22:10:00 EST

Trading gas nozzles for electric sockets may be the green thing to do -- in more ways than one -- but wouldn't plug-in hybrids and electric vehicles be that much sweeter if you could just forget about the plug? That's what Evatran is trying to do with its Plugless Power technology, shown off at Plug-In 2010 in San Jose, which charges your car automatically when you pull up to the company's specially-designed curb. The "station block" above is a wireless induction charger (yes, a car-sized Powermat) that beams electricity to a shoebox-sized device you mount to the undercarriage of your vehicle, magnetically detecting and gravitating towards said shoebox even if you park somewhat crooked. The system presently works with 80 percent efficiency when firing electrons across a two-inch gap (engineers are shooting for 90 percent by the time it hits production) but of course the base station itself doesn't get power from the ether -- it requires one of the company's own Level 2 wired chargers (and compatible wiring) to run. Should your residence or place of business be equipped, the 240 volt towers will set you back $3,245 this December, and the proximity charger will be available to early adopters in Q2 2011 (we're hearing April) for the bargain price of $800.

Qi wireless power standard finalized, universal contactless chargers look closer to reality than ever

Vlad Savov — Mon, 26 Jul 2010 02:34:00 EST

The Wireless Power Consortium took a big step forward this past week with the confirmation that its precocious Qi interoperability standard has been finalized. Composed of three documents setting out the interface, performance and compliance requirements, the new dictum has set itself the not inconsiderable challenge of making wireless charging universal, so that any Qi-approved phone can soak up juice from any Qi-verified base station, dock or omnitool. This first spec is limited to devices requiring no more than 5 Watts, an appropriately humble early goal, though cauldrons are already bubbling with ideas for laptops and the like. We just hope the impressive list of big time companies on the Consortium will succeed in taking Qi into the mainstream -- who here hasn't dreamt of their phone being compatible with the Touchstone?

MIT researchers demonstrate more efficient wireless power

Donald Melanson — Wed, 14 Apr 2010 13:13:00 EST

MIT researchers have been working on wireless power longer than most (Nikola Tesla aside), and it looks like they've now made a somewhat surprising discovery that could lead to more efficient wireless power. In addition to reducing the size of the transmitters and receives used in their system to something approaching practical, the researchers found that the system's efficiency at transmitting energy increased "significantly" if multiple devices are charged at the same time. What's more, while the amount of power transmitted in the latest experiment only amounted to 100 watts, MIT's André Kurs says that is only limited by the amplifier used for the transmitting coil, adding that the system could easily "feed power to a medium-sized room and power a dozen devices."

Case-Mate's Hug wireless iPhone charging solution shipping now for $100

Darren Murph — Tue, 09 Mar 2010 07:38:00 EST

Remember that wireless induction charger that we saw poking around at the CES iLounge Pavilion earlier this year? Seems that Case-Mate has finally given that little doohickey a name, a price and a ship date. The aptly-titled Hug (which consists of the Hug Case and Hug Pad) slips onto one's iPhone 3G or iPhone 3GS and allows Apple's darling to get recharged by simply laying on the aforementioned platter. Of course, the case itself is distractingly bulky, and this whole thing relies on the same eCoupled technology that we've been seeing for years now -- though, the fact that this pad will charge any other case that utilizes the same standard is worth noting. Is the ability to never need your dock connecting cable for rejuvenation purposes really worth the $99.99 asking price? We're guessing not, but those that disagree can get their own shipped out this very moment.

MIT jumps straight to wirelessly powering multiple devices

Darren Murph — Wed, 24 Feb 2010 00:40:00 EST

Ah, wireless power. One of those mythical mysteries that are far more likely to remain "something to strive for" rather than "the next big thing." Oh sure, we've got Palm's Touchstone and the Powermat, but until we can hang a 50-inch plasma from our bedroom ceiling and power it up without a single wire, we'll remain firmly unsatisfied. Thankfully for those of us in that camp, MIT exists, and a few of the school's best and brightest are toiling around the clock in order to develop a technology that would power not one, but multiple devices sans cabling. Thanks to the wonders of coupling resonance, we're told that the "overall power transfer efficiency of the wireless system could be increased by powering multiple devices simultaneously, rather than each device individually." In theory, the system could be implemented by "embedding a large copper coil in the wall or ceiling of a room," but there's obviously no set time frame for release. We'll be looking for you geeks at CES next year, okay?

Wireless power takes another baby step at CES 2010 with Qi standard

Nilay Patel — Tue, 12 Jan 2010 18:01:00 EST

It's our third year visiting with Fulton Innovation and the eCoupled wireless power booth at CES, and once again there's significant progress to be seen -- this time in the form of actual shipping products like the Case-mate Hug and the Dell Latitude Z. Fulton's really pushing the industry standard angle with eCoupled -- it's a founding member of the Wireless Power Consortium, which is just a few months away from finalizing a standard based on eCoupled called Qi. Qi's going to be backed by some pretty big names: Motorola, Nokia, RIM, Energizer, Duracell, Samsung, and Philips are all members of the WPC, along with several others, and the goal is for all this stuff to seamlessly play together. Fulton had some pretty hot demos to show off of the standard in action, including a Toyota Avalon interior with functional spots for two phones, a GPS, a Bluetooth headset, and a netbook, a slick first-class airline seat with a charging table, and a hotel room with several power points -- including a slick motorized dock built into the desk for the Dell. Our favorite demo, however, was a wall sconce: an eCoupled point in the wall was used to power a light fixture, which was then swapped for a digital photo frame. Nifty stuff, indeed.

Still, the big challenge for Fulton and the WPC is going to be actually shipping a bunch of these products this year -- standards are nice, but without gear in hand they're meaningless, and the rival PowerMat crew has been making a pretty big push of its own. We'll see what happens in the next few months -- and how much has changed at CES 2011. Check a couple videos after the break!

Fulton Innovation shows off mid-range eCoupled wireless power

Donald Melanson — Tue, 29 Dec 2009 20:16:00 EST

Fulton Innovation has made some fairly impressive demonstrations of its eCoupled wireless power technology (along with a few less than impressive ones), but most of those have left little space between the power source and the device being powered. As you can see above, however, that's now changed in pretty a big way, with Fulton taking to YouTube to show off a new mid-range inductive power system. While it's obviously not quite ready for home use, this slightly unnerving contraption does indeed appear to work as promised, with it able to power a 12 watt lamp at a distance of 35 inches, or light up an LED at various points in between. Head on past the break to check it out this bit of black magic for yourself.

Swarm robot project sounds ominous, uses open source

Vlad Savov — Mon, 16 Nov 2009 10:44:00 EST

Why would you want to build a 100-strong swarm of mini robots? Well, aside from having them as your minions, you might be able to learn about "artificial self-organization," and "control in large robotic groups," which should come in useful during the inevitable robot insurrection. The swarm robot project, undertaken by the Universities of Stuttgart and Karlsruhe in Germany, aims to produce mini drones that can communicate with one another to avoid collisions, while keeping to a volume of less than three centimeters cubed. Built using open source software and hardware (full list of components is available under the GPL), the latest prototype, titled Jasmine III, achieves those goals while also being able to run "perpetually" thanks to a wireless charging platform. You can see it in close-up after the break, or hit the read link for all the geeky details.

Nokia plugs itself into the Wireless Power Consortium

Donald Melanson — Fri, 02 Oct 2009 20:17:00 EST

The Wireless Power Consortium has already managed to attract some pretty big players in the industry (including Philips, Sanyo and Duracell), but it's now bolstered its roster with one of its biggest heavyweights yet by announcing that Nokia has signed on as a full member. Of course, Nokia isn't making any firm promises about incorporating the Consortium's Qi wireless power standard into its products just yet, but it does say that the technology "carries significant potential to enhance consumer experience of battery charging," and that it "aims to meet these consumer expectations." For its part, the Wireless Power Consortium is unsurprisingly thrilled to have Nokia on board, noting that the move "significantly expands the potential market traction of the Qi wireless charging standard."

Sony dives into wireless power game, makes it way more interesting

Darren Murph — Fri, 02 Oct 2009 02:17:00 EST

We've been watching wireless power startups spin their wheels for years on end, and while we've netted a few contact-charging solutions along the way, there's still a dire need for bona fide wireless power. A most unlikely candidate has just shown up to deliver that very need, with Sony's wireless power supply system reportedly pushing some 60 watts of juice across 50 centimeters (nearly two feet) of crisp, cool air. Currently, the magnetic resonance setup is running at about 60 percent efficiency, but we're sure the engineers behind the breakthrough aren't satisfied yet. So, should we expect to see a prototype BRAVIA HDTV at CES 2010 that needs no AC cable to function? Please Sony, say yes. Say it emphatically.

Video: WiTricity is back, promises wireless power within 18 months

Vlad Savov — Fri, 24 Jul 2009 08:02:00 EST

What started out as an MIT project two years ago has now progressed into a full-fledged company -- ladies and gentlemen, meet WiTricity Corp. Auntie Beeb (that's the BBC for you Yanks) has grabbed the firm's CEO Eric Giler to discuss some pretty aggressive plans for bringing wireless power to the masses. Yes, we're talking actual through-the-air wireless as opposed to something like Palm's Touchstone, which requires physical contact between charger and chargee. Based on magnetic induction, the magical technology is apparently mature enough to be deployed in the relatively near future, and if all goes to plan, "near future" could translate into "18 months from now." Also of note, Intel is hard at work developing the original concept, and if the parallel engineering of the same idea by two companies isn't enough to get your skepticism dialed down and your browser to the video past the break, what is?

Nokia hopes to one-up Touchstone, harness wireless power for "ambient" phone charging

Paul Miller — Tue, 09 Jun 2009 16:14:00 EST

Like a page torn right out of the government's top secret files on Nikola Tesla, a Nokia research team is working on a wireless energy harvesting mechanism, which sucks up all that cancer-giving RF floating through the air and turns it into electrical current. Their goal is about to capture about 50 milliwatts of power for "ambient charging" -- which would at least be enough to top off the battery while the phone is off. Unfortunately, right now their current prototypes are only pulling down 3 to 5 milliwatts, and many in the industry are convinced it can't be done (don't worry, Nokia, that's just The Man, keeping you down). To be honest, we're not totally sure were comfortable with the thought that there's enough RF floating around to make this even theoretically possible, but as we slowly come to grips with our own mortality, we imagine we'd gladly pay an extra $70 or so for the privilege of never having to charge our phone again. Nokia itself isn't over promising: they plan on supplementing this juice with solar power, and thinks it'll be three or four years until it makes its way into a handset -- probably around the time your existing iPhone contract dries up.

Palm Pre Touchstone to be an entire product line, not just a charging dock

Nilay Patel — Sun, 12 Apr 2009 17:11:00 EST

Although Palm's reps basically stick to the same script when giving out those lengthy Pre walkthrough demos, every now and again they'll let something interesting slip -- like the fact that the Touchstone inductive charging dock is just the first product in an entire line of Touchstone wireless products. It's not clear if that simply means that "Touchstone" will be Palm's wireless power branding, or if there will be Touchstone products that do more than simply charge devices, but we're certainly eager to find out more -- and hopefully soon. Video clip after the break.

Fulton Innovation has a wireless power coming out party at CES

Nilay Patel — Thu, 08 Jan 2009 22:56:00 EST

It was just a short year ago that we went to Fulton Innovation's tiny booth at CES and failed to get a working wireless power demo, but a lot's happened since then -- the company is at CES 2009 in force, with a much larger, swanker booth, partners like Energizer and Motorola demoing working products, and tons of working real-world examples of the tech in action. We were particularly taken with the modded Dish DVR that automatically turned itself on and off when the remote was placed on top of it to charge up -- oh, and the remote featured super-capacitors instead of batteries that charge fully in 10 seconds. There were also a ton of cell phones (including a modded iPhone, of course), new cooking demos featuring a blender, and a super cool Leggett & Pratt power tool charging workbench. Extremely impressive, all in all -- we're starting to think that 2009 could be the year that wireless power could really take off. Gallery below, video after the break!

P.S.- We asked if Fulton had anything to do with the Palm Pre's sexy Touchstone wireless charger, but the guys in the booth didn't know. We'll let you know if we find anything out.

Powermat hands-on

Ross Miller — Tue, 06 Jan 2009 23:58:00 EST

Remember the Powermat? Unlike other induction-based "wireless power" contraptions we've seen, this one came out earlier this year as total vaporware and has now resurfaced as a collaborative effort by Michigan-based HoMedics Powermat North America (HPNA). We finally got a chance to see it work in person and, much to our surprise, it seems to have delivered on its promised... at least in part. We saw three pads that touched base with six different mediators for charging various cell phones, laptops, and handheld games. The devices magnetically "lock on" to the mats and a light comes on to indicate its working. The rep told us devices charge just as fast with the mat as they would via the traditional "plug" method, but it's not like we waited around long enough to see for ourselves. No price or date, but we're a lot more excited about it knowing this thing might actually work. We're hearing some more interesting developments will be shown off later this week, from both Powermat as well as a few of the other companies here showcasing wireless power technology, which we'll be keeping an eye out for. Hit up the gallery for some sexy recharging imagery.

Mojo Mobility's induction charging tech: best thing to happen to discs since Tron

Tim Stevens — Thu, 13 Nov 2008 10:19:00 EST

We are absolutely, completely ready for wireless induction charging to make it big. Have you seen our gadget charging station? It's like some Lovecraftian nightmare; our latest intern went over to plug in his BlackBerry two days ago and we haven't seen him since. For years we've been getting teased with limited, proprietary solutions (mostly for sweaty videogame controllers) but we seem to be firmly and disappointingly locked in the competing standards phase. While we hate to see yet another contestant enter the fray, Mojo Mobility Inc. might just have a winner with its Near Field Power technique, relying on thin, inexpensive coiled discs to both send and receive up to 4 watts of power with 70 percent efficiency. Unlike the competition no exposed contacts are required, and while it looks like you'll still need to place the device onto a charging pad, with multiple transmission discs that pad could charge all your gadgets at once. Mojo plans to supply the receiving discs to battery and device manufacturers in the near future, and to that we can only say hurry up. Think of the interns!
