Georgia Tech develops self-charging battery that marches to the owner's beat
One of the last times we saw the concept of a self-recharging battery, it was part of a high-minded Nokia patent whose ideas still haven't seen the light of day. Researchers at Georgia Tech are more inclined to put theory into practice. Starting from a regular lithium-ion coin battery, the team has replaced the usual divider between electrodes with a polyvinylidene difluoride film whose piezoelectric nature produces a charging action inside that gap through just a little pressure, with no outside voltage required to make the magic happen. The developers have even thumbed their noses at skeptics by very literally walking the walk -- slipping the test battery under a shoe sole gives it a proper dose of energy with every footstep. At this stage, the challenge mostly involves ramping up the maximum power through upgrades such as more squeezable piezoelectrics. Georgia Tech hasn't progressed so far as to have production plans in mind; it's nonetheless close enough that we could see future forms of wearable computing that rarely need an electrical pick-me-up.
Adidas Social Media Barricade shoe concept moves tweets to the track (video)
Adidas is known for making connected shoes -- but never quite as linked-up as a Nash Money concept making its appearance late into the London Olympics. The Social Media Barricade weaves the guts of a phone and a basic two-line LCD into a running shoe, letting the footwear take Twitter updates very literally on the run through a public account. Even the signature Adidas stripes change their hue through remote control. Before anyone gets visions of athletes checking congratulatory tweets after the 100-meter sprint, just remember that it's an idea rather than a production blueprint: although Adidas is quick to call the Social Media Barricade the "future of athlete connectivity," the only athletes putting eyes on a pair right now are those swinging by the Olympics' media lounge for interviews. Knowing this, we can still imagine some future shoes padding runners' egos at the finish line during the 2016 Rio games.
NCSU creates stretchable conductors from silver nanowires, lets gadgets go the extra inch
As often as we've seen flexible electronics, there haven't been many examples that could stretch -- a definite problem for wearables as well as any gadget that could afford to take a pull or squeeze. North Carolina State University's Yong Zhu and Feng Xu may have covered this gap through a form of silver nanowire conductor that keeps the energy flowing, even if the wire is stretched as much as 50 percent beyond its original length. By coating the nanowires with a polymer that traps the silver when solid, the researchers create an elastic material that can crumple and let the nanowire take the strain without interruption. Although the stretchy conductor's nature as a research project could put any practical use years into the future, Zhu notes that it can take loads of abuse, making it a perfect fit for rugged mobile devices. It should also allow for robots with a gentler touch and a more natural look... although we'll admit we're skittish about the creepy androids likely to follow.

Google unveils $1,500 Project Glass Explorer Edition, takes pre-orders for 2013 only at Google I/O
We've been wondering when non-Googlers could get their hands on Project Glass in earnest, and now we know: the company is opening up pre-orders for Glass Explorer Edition, a developer version of its heads-up display glasses. How much it's changed from the prototypes isn't yet known, but Google has said that it's been steadily working on refining the hardware along with the software. Sadly, the first crack at the wearable technology isn't coming to the broader masses just yet. Orders are only available to Google I/O attendees, and they cost a pretty hefty $1,500 for their release sometime next year. Check out our full coverage of Google I/O 2012's opening keynote at our event hub!
PLX's XWave Sport gives brainwave interfaces a casual look, triggers '80s flashbacks
Brainwave-guided interfaces are common. Most of the time, though, they're not what we'd call subtle. PLX Devices hopes to have that licked through the XWave Sport, a brain interface that disguises all its sensors through a fuzzy, exercise-friendly headband. Underneath the incredibly 1980s-retro (but washable!) look, you'll get about six hours per charge of tracking for concentration, relaxation and other noggin-related data that can transmit over Bluetooth to apps for Android, iOS or old-fashioned PCs. An SDK is available now, but pre-orders for the $100 XWave Sport won't ship until September 20th. That should give us enough time to perfect our Flashdance reenactments.
Sony patent filing for glasses would share data face to face, carry more than a hint of Project Glass
Google might not realize it, but Project Glass isn't alone in the patent race these days. Sony has quietly applied for a patent on a familiar-looking smart glasses system whose advantage over Mountain View would be an emphasis on things in twos. Eyepieces are the most obvious, but Sony is also keen on sharing data between two friends: transmitters on a pair of glasses would send personal info through a likely very uncomfortable glance at someone else with the same eyewear. If your friends are more than a little weirded out from sharing by staring, the proposed glasses could still pick up information from visual tags on posters, products and virtually anything else. There's even the obligatory connection to a watch for sharing data with the rest of the world. Whether or not the patent leads to Sony head-mounted technology more advanced than a personal 3D TV is still up in the air, especially with Google currently hogging the spotlight... not that existing, more conservative designs have ever stopped Sony from rolling out wild concepts before.
Copper-nickel nanowires from Duke University could make ubiquitous printable circuits
Nanowires, although they're building steam, still have to overcome the not-so-small problem of cost -- they often have to use indium tin oxide that's not just expensive, but fragile. Duke University has developed copper-nanowire films that could remedy this in style. The choice of material is both a hundred times less expensive to make than indium and is much more durable. It's flexible, too: if layered on as a coating, the nanowires would make for considerably more viable wearable electronics that won't snap under heavy stress. The catch, as you might suspect, stems from the copper itself, which doesn't conduct as much electricity as indium. The nickel will keep your copper electronics from oxidizing faster than the Statue of Liberty, however. Any practical use could be years away, but further successes from Duke could quickly see printable electronics hit the mainstream power and power our dreams of flexible displays.
Custom-made Aperture Science gas mask will make sure you're still alive, won't open portals
Valve's Portal series has been used as the pretext for many achievements outside of puzzle gaming, including getting hitched. Keeping you from shuffling off this mortal coil, however, is still new. Two Horns United has given a gas mask a decidedly nerdy visual upgrade that resembles the game's iconic Aperture Science Portable Quantum Tunneling Device, right down to the light-up energy chambers. Best of all, unlike some homebrew projects, you'll have a (probably limited) chance at buying one yourself after June. Coworkers might look at you oddly as you strap a portal gun to your face during a safety drill, but you'll have the quiet satisfaction of knowing you're truly ready for a neurotoxin attack, not to mention taking the title of a Jonathan Coulton song very literally.
Google patent application could give Project Glass one true ring controller to rule them all
Let's face it: right now, the head nods and other rudimentary controls of Google's Project Glass are mostly useful for looking good, sharing photos and not much else. A US patent application submitted last September and just now published, however, raises the possibility of more sophisticated control coming from your hands. A ring, a bracelet or a even a fake fingernail with an infrared-reflective layer would serve as a gesture control marker for a receiver on heads-up display glasses. Having this extra control would give the glasses-mounted computing room to grow by learning gestures, and it could even depend on multiple ornaments for more sophisticated commands -- at least, if you don't mind looking like a very nerdy Liberace. We can imagine the headaches a hand-based method might cause for very enthusiastic talkers, among other possible hiccups, so don't be surprised if Project Glass goes without any kind of ring input. That said, we suspect that Sauron would approve.
FCC wants to set aside wireless spectrum for medical body area devices, our hearts are literally aflutter
The FCC has been making a big push towards freeing up the airwaves for medical uses, and it just took one of its biggest steps on that front by proposing to clear space for wireless body area networks. Agency officials want to let devices operate in the 2.36GHz to 2.4GHz space so that patients can stay at home or at least move freely, instead of being fenced in at the hospital or tethered to a bed by wires. Devices would still need the FDA's green light, but they could both let patients go home sooner as well as open the door wider for preventative care. Voting on the proposal takes place May 24, which leaves our tech-minded hearts beating faster -- and if the proposal takes effect, we'll know just how much faster.
Microsoft granted patent for wearable EMG device
Those muscle spasms? They're now good for something. Okay, so Microsoft's just-granted patent for a wearable EMG device doesn't really thrive off of involuntary twitching and such, but it does use your movements to control your smartphone, notebook and other gadgets. The "Wearable Electromyography-Based Controller," which we first glimpsed back in 2010, uses sensors to interpret the electrical signals generated by a user's muscles, and then communicates with the wearer's computer via a wireless (or wired) connection. Redmond envisions the wearable device in various incarnations: as an armband equipped with sensors, a shirt, eyeglasses and even nodes attached directly to the user's body. In the armband example, motion control could be used to interact with a PMP while the user is jogging. No matter the setup, a calibration process allows the system to locate specific sensors and collect information based on specific gestures or movements, which means playing Guitar Hero with only an air guitar may someday be a reality after all.
Microsoft Research's shoulder mounted system makes anything a multitouch display
Remember the nifty new 3D transparent display, augmented reality mirror, and remote sharing technology that Microsoft revealed just over a week ago? Turns out that Redmond's research arm wasn't done doling out the gadget goodies, as it's now showing off a new Wearable Multitouch Projector that turns any surface into a gesture-sensitive display. Using Kinect-style motion and depth sensing cameras in concert with a pico projector and a PC, you can tap, swipe and pinch-to-zoom to your heart's content on the nearest flat surface. It's currently a rather clunky, cabled contraption, but the touch input does appear to work pretty well, and the researchers who built it think that the tech can be miniaturized to a more user-friendly size in the future. See for yourself in the video after the break.
Lumus' OE-31 optical engine turns motorcycle helmets, other eyewear into wearable displays
After showing off a duo of wearable, see-through displays at CES, Lumus is back with a second optical engine -- one that could be used in any style of frames, from prescription glasses to ski goggles. Available in binocular and monocular configurations, the tiny OE-31 sensor weighs just 10 grams (.35 ounces), allowing it to accommodate a variety of form factors besides your run-of-the mill (and quite dorky-looking) 3D glasses. As always, Lumus' hook is its ability to combine head up content, augmented reality and see-through displays, though this time around the sensor allows for a 19-degree field of view and a full-color, 640 x 360 picture. Though that's not as impressive as the 720p, 3D-capable frames on offer at CES, the company argues it should be adequate for reading text, particularly since the viewing experience will be comparable to staring at a 40-inch screen from 10 feet away. No word, of course, on what products might incorporate these discreet head up displays, though maybe, just maybe, we'll catch a demo in Barcelona. For now, we've got photos below along with a handful of demo videos after the break.
AR goggles take crime scene technology to CSI: Miami level
Dutch researchers are looking to catapult crime scene investigation into the 21st century through the use of augmented reality (AR). The prototype system, designed by the Delft University of Technology, employs a pair of AR goggles, two head-mounted cameras and a portable laptop rig to allow investigators to build virtual crime scenes by tagging evidence and placing objects they are viewing. After mapping an area, additional law enforcement personnel can review the investigator's work and request additional information -- asking the CSI to define or place additional objects. Researchers hope that the 3D renders will be used as court-admissible evidence in the near future; the technology is set to be tried on a real Dutch crime scene later this year. We can see it now: Lieutenant Horatio Caine whips off his shades and tosses on a pair of (equally stylish) crime-fighting goggles... YEAAAAAAAAH!
New Year reveler crafts Kanye-approved EL Wire glasses: light up as the bass pounds (video)
The bar-laden spectacles that Kanye West popularized have just been reborn, and dare we say, they're harder, better, faster and stronger. YouTube user ch00ftech decided to borrow a few good great ideas while adding in a few twists of his own, resulting in the creation of EL Wire Kanye glasses that actually light up when the beat pulses. There's a deep, deep dive into the technicalities down in the source link, but for the 99 percenters in attendance, the video just below says it all.
Click KeyPad Watch is the timewasting retro-timepiece you've been waiting for
We do like a good indecipherable timepiece 'round these parts and Click's KeyPad certainly fits the bill. Resembling an old-school mechanical numerical keypad, each button packs an LED -- press any number and it'll blink out the time in single digits, so if it was 9:15am, the zero, nine, one and five buttons would flash in sequence. Push the hash key and the watch will oblige you for today's date. If you enjoy frustrating colleagues who ask you for the time, then you'll be delighted to hear that it costs $90 and is shipping now. However, we're not sure we could pull one off -- maybe the hipster down the street will have better success.
Scientists testing HUD contact lenses on rabbits, hope to bring augmented reality to your eyeballs
Scientists at Washington University are a step closer to bringing us all some sweet information displaying contact lenses. The team has been successfully testing prototype lenses on rabbits -- though there are some major caveats here. First, due to limits of circuitry, they can only display a single light-emitting diode at a time. Also, the scientists have yet to figure out a workable energy source -- at present, they need to be within centimeters of a wireless battery. The researchers have big plans, however, including the display of holographic images -- and, no doubt, information about which targets to destroy.
Nike teases Back to the Future shoes, creepily leaks the contents of Marty McFly's closet (video)
What's this? Nike is rounding up shoe-nerds (and Back to the Future fans) to taunt them with futuristic metal shield glasses, 1980s candy, and a personal messages from Doc Brown? Could this shoe-filled YouTube tease (uploaded by DocEmmettBrown88) mean that Nike is bringing nerdom's coolest kicks back from the future? Probably. After all, you don't patent power-laces just to make a normal shoe, do you? [Thanks, Rob]
