Flexible wireless charging sheet could eventually turn your skinny jeans into power pants (video)
If you haven't already heard, wireless charging is all the rage -- cars, cameras, and, of course, cellphones have all benefited from the burgeoning technology. Now a team of researchers at Japan's National Institute of Information and Communications Technology (NICT) are showing off a 2D power transmission system that could turn your pockets into wireless charging stations. According to its creators, "When a 2.4GHz high frequency signal is transmitted through the sheet, it becomes a wireless conductive object." Electromagnetic waves are captured in the sheet and can be concentrated in particular areas, allowing for individual activation of multiple devices, and thus increasing efficiency -- systems like Qi currently require a dedicated transmitter per device. The NICT says the power it provides is still relatively weak -- about 1W -- but it has plans to eventually bring the technology to soft fabrics. So maybe that Snuggie charging station you've been dreaming of isn't so impractical after all.
NHK's flexible OLED is both literally and figuratively green (video)
When it's not pushing Super Hi-Vision, the hopeful 7,680 x 4,320 successor to HD, NHK also dabbles in small, flexible OLED panels. The Japanese public broadcaster recently showed off a 5-inch prototype display that, while bearing a heavy green tint and very noticeable rows of dead pixels, was still a significant improvement over a similar screen it demoed in 2009. Sure, it's not quite as flexible or vibrant as Sony's rollable OLED from last year, but it does seem to suffer from fewer bad pixels -- an important step towards maturation. Don't miss the video after the break which offers some pretty nifty glimpses at a number of bendable OLEDs. It's clear the tech is still a little wet behind the ears, but we're definitely getting closer to a future populated with TVs that roll up for storage and e-readers that fold like a paperback.
Sony unveils flexible color e-paper, new glasses-free 3D LCD displays at SID 2011
We saw some fancy panels and flashy lights on the show floor at SID this week, but Sony decided to keep its latest display offerings tucked away in an academic meeting. We're getting word today from Tech-On! that the outfit unveiled a 13.3-inch sheet of flexible color e-paper as well as two new glasses-free 3D panels in a separate session at the conference. New e-paper solutions loomed large at SID, but we were surprised by the lack of flexible screens. Sony's managed to deliver both on a display that weighs only 20 grams and measures a mere 150-microns thick, a feat made possible by the use of a plastic substrate. The sheet boasts a 13-percent color gamut, 10:1 contrast ratio, and 150dpi resolution. As for the 3D LCD displays, Sony joined a slew of other manufacturers in showing off its special brand of the panels. These new displays, ranging from 10-inches to 23-inches, apparently employ a new method for delivering 3D to the naked eye. This particular method uses a backlight positioned between an LCD panel and another backlight for 2D images, and can be easily be switched off for 2D viewing. Of course we would have liked to see these screens in the flesh, but alas, Sony decided to play coy. Hop on past the break for a shot of the new 3D panel.
UDC shows off serpentine OLED lamp concept at SID 2011 (video)
We've seen flexible OLEDs and OLED lighting solutions before, but none of them conjured our sweaty club-hopping fantasies quite like this concept from Universal Display Corporation (UDC). The flexible OLED makers weren't particularly forthcoming on the specs for this color-changing apparatus, but we can tell you that it uncoils and recoils with the help of a motion sensor, and requires very little energy to power -- note that tiny wire supplying 100 percent of the required juice. UDC used this flashy lamp specifically to show off its own brand of low-energy flexible white OLED lighting, which means you won't see it popping up in B.E.D. anytime soon (if ever), but it certainly has us thinking of new ways to light up our nights. Gratuitous amounts of bouncing and beaming can be found after the break. %Gallery-123940%
Flexible PaperPhone wants to get bent out of shape (video)
We love our smartphones (in part) because they're flexible, in the sense that they are mighty multitasking machines. Researchers from Queen's University in Ontario Canada, however, want flexible phones in a literal sense -- less five-tool player, and more master contortionist. Using a ductile e-ink display and elastic electronic underpinnings, they created a device called the PaperPhone that literally bends to its user's will. Curling the corners of the device isn't just for show, either, as folding the phone is how users navigate menus and make calls. We aren't completely sold on the idea of a bend-based UI, but we're definitely digging the lithe and lightweight phone form factor. Video of the new flexi-phone is after the break. Update: A second video showing the same 3.7-inch display in a wearable computer project dubbed, "snaplet," has been added after the break.
Scosche freeKEY Bluetooth keyboard: A hands-on test
A few days ago I highlighted a new flexible and water-resistant Bluetooth keyboard from the folks at Scosche. As many of the people commenting on that post noted, flexible "chiclet-type" keyboards of this type have a reputation for being difficult to type on. TUAW blogger Erica Sadun mentioned that when she's used chiclet keyboards, her fingers have actually started to hurt after a short amount of time due to the extra pressure required to depress the key switches. After hearing that from Erica, it was with a great deal of skepticism that I opened a box from Scosche the other day that contained one of the freeKEY Bluetooth keyboards. Is the US$59.99 ($49.99 through Amazon.com) freeKEY a good portable keyboard for iOS device owners who want to travel light, or does the design of a keyboard like this keep it from really being useful? In the following review (see next page), I'll provide a hands-on test of the freeKEY with an iPad 2 and let you know how it held up to my lightning-fast typing.
New silver-packing transparent conductive film could mean more durable touchscreens
We first heard of the wonders of silver ink back in 2009, but it wasn't until earlier this year, with talk of 3M's new capacitive touchscreens, that we experienced its real-world potential for display technology. Well, it looks like 3M's not the only name in the Ag game, in fact Tokyo-based Toray Industries recently announced the development of a transparent conductive film that ditches the traditional ITO (indium tin oxide) for silver wire. In order to produce this new material, a layer of Ag wires, measuring several hundred nanometers, is applied to a polyester (PET) film by way of a wet method. The result, the company said, is a more flexible, durable, and transparent film that is well suited to touchscreens of just about any size. There's no word yet on when the film will appear on real-deal devices, but we'll definitely keep an eye out for the silver screens. Full PR after the break.
Flex testing iPad glass
The folks at iFixYouri had some glass panels from an iPad 1 and an iPad 2 laying around the shop and did some informal tests to see which panel would break under stress. An earlier analysis by iFixit revealed the glass in the iPad 2 was 27% thinner than the iPad 1. The California repair company questioned whether this would affect the durability of the iPad 2's display. Boston repair shop iFixYouri tries to answer this question in a video that features extreme bending, breaking glass and a catchy soundtrack. Read on to watch the iFixYouri video and let us know in the comments which display you think holds up better under pressure. Hint: bigger isn't always better. [Via 9to5mac]
Apple patent woos with tales of ultra-slim audio connectors for lusciously thin devices
We're still a long way from reaching the point where our gadgets can't get any thinner and, while the 8.7mm iPod Shuffle is just about king of the hill for the moment, Apple is already envisioning a future where where the humble 3.5mm audio jack is too thick. A recently revealed patent application called "Low Profile Plug Receptacle" describes a number of different ways to create audio ports that are thinner than current models but yet won't take us back to the sinister miniUSB adapter days of yore. One of the potential solutions has a "semi-flexible" housing that expands willingly to receive your headphones' clumsy attentions, while another is recessed beneath a pair of doors that flip open to make room when the plug is inserted. As always with these applications there's no reason to believe they'll be ever appearing in a consumer device, but that doesn't mean we can't dream of a future where the gold-plated jack on your buds is thicker than the bulkiest part of your phone.
NanoPhotonica develops S-QLED, OLED to develop inferiority complex soon
Ahh, the wonders of OLED -- flexible displays, great viewing angles, and low power consumption. However, the folks at NanoPhotonica have "perfected" a quantum dot display technology called S-QLED that allegedly has superior picture quality, uses 30 percent less power, and costs three-quarters less than its OLED competition. The company is gearing up for mass production and is in talks with several OEMs to start producing S-QLED displays, but unfortunately there's no timetable for when they'll get to market. Guess we'll have to wait a bit longer to see just how perfect these QLEDs really are.
Flexible batteries get the graphene treatment, could be cheaper than other bendy batts
We've been talking about flexible batteries for years now, but a team of Korean researchers have presented a new solution to bendable energy sources that is not only more powerful than standard lithium-ion batteries, but also potentially cheaper to produce than its malleable predecessors -- and unsurprisingly, everyone's favorite wonder material, graphene, is at the heart of the innovation. The rechargeable battery contains a vanadium-oxide cathode, grown on a sheet of graphene paper, an unidentified separator, and an anode made of lithium-coated graphene. According to the folks behind the new power source, it sports higher energy and power density, as well as a better cycle life than the literally stiff competition. Similar advances have also out-performed rigid lithium-ion batteries, but have enlisted carbon nanotubes, a material more expensive to produce than graphene. Of course, like all technological advances, we won't be seeing these things for years, if not decades, so you might as well get used to ye olde standard bearer.
Samsung buys Liquavista, dives headfirst into electrowetting displays
Samsung's got a reputation for building crazy awesome display technologies, and it just added another one to the stack -- with the buyout of Philips-spinoff Liquavista this December, it's gained quite the foothold in electrowetting. In case you're not familiar, electrowetting has been repeatedly pitched to us as pretty much the Holy Grail of displays: flexible, colorful, unbreakable, outdoor-readable e-paper screens with high refresh rates and low-power consumption that can be manufactured on existing assembly lines. We'll have to see if the theories equate to meaningful products, but we imagine ownership by Samsung can't hurt one bit, especially as the company says it will "expand its leadership in next generation display technologies by pioneering the application of electrowetting in e-Paper and transparent displays." Sounds like a commitment to us. PR after the break. Update: Seems that The Digital Reader actually figured out about the deal yesterday -- read the original scoop at our more coverage link!
Reebok sets sights on flexible computing sportswear, partners with startup team
Science has prototyped flexible versions of just about everything a ever-loving geek needs: displays, memory, batteries, LEDs, speakers and an input device or three. Now, Reebok's looking to put some of that computing power up our sleeves. The apparel manufacturer's teamed up with MC10 -- a startup founded by our old friend John Rogers, who helped pioneer the field -- with the intent to build "conformable electronics" into high-performance clothing for athletes over the next couple of years. Though the company told MIT Technology Review the devices typically consist of thin silicon strips printed onto flexible materials, and that they might they might measure metabolism and performance using embedded sensors, hard details are few -- the only thing we know for sure is that a flexible tech scientist just scored a partnership with a major company, and we're hopeful they'll make something neat. PR after the break.
NEC develops thin, flexible and 'practical' Organic Radical Battery
NEC first announced its super-thin Organic Radical Battery (or ORB) technology a full five years ago, but it's now finally back with what it describes as the first "practical" prototypes of the batteries. While these new batteries are about twice as thick as NEC's first such units, they're still only 0.7 mm thin, and are apparently much more reliable while also delivering 1.4 times more output (specifically, a capacity of 5mAh). The key to that boost, it seems, are some newly developed, highly conductive cathodes, which consists of some solid organic radical material that were turned into a gel and then uniformly compounded with carbon materials. What does that mean for actual consumers? Well, if NEC has its way, the batteries could be a thin, flexible power source for things like smart cards, wearable devices, and flexible e-paper displays. Full press release is after the break.
Flexible metamaterial could make your next invisibility cloak rather more comfortable
Metamaterials have a lot of potential future applications, but only one of them really gets our geeky senses tingling: invisibility cloaks. Previous theoretical examples we've seen were built upon rigid silicon substrates, meaning they'd be about as comfortable to wear as a motherboard jacket with ISA sleeves. But, a new material at the University of St. Andrews has been created that offers similar light-bending properties in a flexible package, crafted by the formation of a membrane upon a release layer, etching microscopic gold bars upon it, and then removing the release layer to have just the blingy membrane left behind. It can be tuned to bend various wavelengths, with the team having success working at wavelengths as short as 620nm -- you know, red. If there's one problem it's the size of the thing, with current prototypes measuring just 5 x 8mm, but it is said to be "scalable to industrial levels," meaning next-year's Harry Potter costume could be the best one ever.
Samsung showcases 4.5-inch flexible AMOLED, may actually mass produce this one
For all intents and purposes, every single flexible display we've seen over the past few years has eventually been filed in the "awesome things that'll never materialize" drawer. There are exceptions to that rule, mind you, but we've largely been frustrated by how often these things pop up at trade shows and then vanish forever. Samsung Mobile Display, however, is hoping to change that. According to reports stemming from FPD International 2010, this here 4.5-incher is dangerously close to production, and given the lustworthy 800 x 480 resolution, we couldn't be more excited about the possibilities. We're told that Samsung is eschewing the traditional glass substrate in favor of a newfangled plastic version, and evidently it's a heck of a lot easier to mass produce. After all, we're still waiting for this thing, guys.
Liquavista displays get flexible, 'unbreakable,' still rather theoretical (video)
The next generation of display technology is still that, next, but despite being a future away it continues to get better. Liquavista keeps wowing us with various demonstrations of its electrowetting technology offering full color, high refresh rates, visibility in all lighting conditions, and low power consumption to boot. Now they're bendy too, with the company releasing footage of a prototype that's flexible. It's also said to be "unbreakable," demonstrated by a person wearing latex gloves gently tapping on the screen -- because, you know, that's about as tough as it gets outside of the lab. Video is after the break, along with full PR, but in neither will you find any hope of seeing this tech for real before the second half of next year.
Flexible, implantable LEDs look set to start a new body modification craze
LED lights are cool, you're cool, why not combine the two, right? We doubt that's quite the reasoning that led to this international research project, but it's certainly an appealing way to look at it. Our old buddy John Rogers from the University of Illinois at Urbana-Champaign has headed up a research team with participants from the US, China, Korea, and Singapore, who have together produced and demonstrated a new flexible and implantable LED array. Bettering previous efforts at inserting lights under the human skin, this approach allows for stretching and twisting by as much as 75 percent, while the whole substrate is encased in thin silicon rubber making it waterproof. Basically, it's a green light to subdermal illumination, which could aid such things as monitoring the healing of wounds, activating light-sensitive drug delivery, spectroscopy, and even robotics. By which we're guessing they mean our robot overlords will be able to color-code us more easily. Yeah, that must be it.
TDK flexes its transparent OLED muscles with CEATEC demonstrations
Finally a bit of competition to pep up the transparent OLED market. Samsung and LG seem to have had this party all to themselves until now, but TDK is stepping in with a 2-inch passive matrix screen and a humble QVGA (320 x 240) resolution. Sure, those aren't groundbreaking specs, but a claimed 50 percent transmittance -- meaning that half of what's behind the screen can be seen through it -- beats its Korean competitors rather handily. Another prototype being shown off by the company is a 3.5-inch flexible OLED panel that redefines thinness with a slinky 0.3mm profile. It's made using a resin substrate and covers an unimpressive 256 x 54 pixels at the moment, but again, that's just how good things get started: with small steps of awesome. We'll keep an eye out for both of these as we prowl the halls of CEATEC 2010.
Sony demoes flexible electronic paper display, tickles our fancy
Say, did the air just get a little richer in vapor? Sony has titillated its home nation with a demonstration of a new flexible e-paper display, which looks set to compete with LG's, HP's, Toshiba's, and hell even Sony's own, flexi-display ventures. Employing a plastic substrate, the above prototype is apparently capable of being rolled up like a regular old newspaper -- presumably fly-swatting is not a problem either -- but we have our usual reservations about yet another flexible display teaser. Oh, they're all gorgeous and revolutionary, it's just that we're not seeing too many of them in our local Walmarts, you know?
