Rohm Wireless Power Transmission system hands-on (video)
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.%Gallery-135773%
Murata Wireless Power Transmission System supports laptops, we go hands-on (video)
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.%Gallery-135770%
Evatran's Plugless Power wireless EV charger gets smaller, conscripts Chevy Volts for testing
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
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)
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. %Gallery-124958%
Power Matt joins the Wireless Power Consortium, gains the power of Qi
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
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
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
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
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! %Gallery-114400%
Texas Instruments ups the wireless power game with industry's first Qi dev kit
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
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
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 3GS. 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
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
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
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
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
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? [Thanks, MrStringTheorist]
MIT researchers demonstrate more efficient wireless power
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
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.
