LG Chem develops very flexible cable batteries, may leave mobile devices tied up in knots
The world is no stranger to flexible batteries, but they've almost always had to be made in thin sheets -- that doesn't amount to a long running time if you're powering anything more than a watch. LG Chem has developed a flexible lithium-ion battery that's not just better-suited to our bigger gadgets but could out-do previous bendable energy packs. Researchers found that coating copper wires with nickel-tin and coiling them briefly around a rod results in a hollow anode that behaves like a very strong spring; mating that anode with a lithium-ion cell leads to a battery that works even when it's twisted up in knots. Join multiple packs together, and devices could have lithium-ion batteries that fit many shapes without compromising on their maximum deliverable power. Some hurdles remain to creating a production-grade battery, such as a tendency for the pack to shed a small amount of capacity whenever it's put under enough stress. LG Chem is fully set on turning these cable batteries into shippable technology, however, and could ultimately produce mobile devices and wearables that really do bend to their owners' every whim.
Apple seeks patent for Smart Cover with embedded secondary display
According to a patent application made public by the USPTO this morning (and originally filed a year ago), Apple believes it's possible to build a flexible display into an iPad cover in order to "greatly enhance" the functionality of the tablet itself. Taking power and data from a dedicated connector on the side of the slate, at least one segment of the name-deserving Smart Cover could be used to augment the main display with space for extra icons, or operate as a separate media control interface, or simply display notifications. Drawings collected in the gallery below also hint at using the entire inner surface of the cover as a keyboard (ala Microsoft Surface) or as a drawing area. As with all patent applications, there's nothing to say such an idea will ever see Californian sunlight, but it'd be crying shame if it didn't.%Gallery-161615%
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.
Corning unveils slim, flexible Willow Glass (video)
That is not plastic in the image above, it's glass. In particular it's a sheet of Corning's new 100-micron-thick Willow Glass, a new ultra-thin and flexible substrate for LCDs and OLEDs. The extreme thinness of the glass should lead to lighter, svelter devices, but it also means that shape is no longer a barrier for design. In fact, Corning expects Willow Glass will eventually lead substrates to be manufactured "roll-to-roll" instead of "sheet-to-sheet" -- similar to how newspapers are printed. Even though the glass is as thin as paper (literally) it doesn't give up its patented Corning toughness. Though, we wouldn't subject this to the same sort of abuse that the more brolic Gorilla Glass is built to withstand. Willow will start showing up in smartphones first, but the company is already looking into additional applications, such as solar cells and lighting. For more, check out the video and PR after the break.
Sharp shows off IGZO LCD and OLEDs including a 13.5-inch QFHD screen
Sharp announced earlier this year that it was starting to crank out LCD panels based on new indium gallium zinc oxide (IGZO) technology and now it's ready to show some off at the Society for Information Display show in Boston. Currently sized for phones and tablets, the first prototypes include a pair of LCDs, one a 4.9-inch 720x1280 display, and the other coming at 6.1-inches with a resolution of 2560x1600. As an example of what will be possible further down the line, it also has a pair of OLED panels, one 13.5-inch 3840x2160 QFHD panel based on White OLEDs with RGB color filters (similar to the LG HDTV recently introduced), and a flexible 3.4-inch 540x960 screen (shown above). According to Sharp the new tech means screens with higher resolutions, lower power consumption, narrower bezels and higher performance touch screens because it enables even smaller thin-film transistors than the ones currently in use. The Associated Press reports it expects to apply the upgrade to production lines in this fiscal year, for now you can hit the source link for a few diagrams and examples of crystalline structures or check the gallery for pics of the other displays. %Gallery-156633%
Insert Coin: Twig, the tiny iPhone cable that's also a tripod (video)
In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. Imagine an iPhone cable that was only four-inches long, doubled as a tripod and could bend to your every whim? That's the idea behind Twig, designed by former WIMM engineer Jason Hilbourne, who wanted something sturdier, smaller and more portable than Cupertino's "limp noodle." In partnership with an iOS accessory maker, the cable's three sturdy prongs will transform into a dock, wrap around objects or create a free-standing tripod for your FaceTime needs. It needs $50,000 to turn from dismembered action-figure prototype to reality, with an $18 pledge enough to secure you one of the first to leave the factory. After the break we've got the pitch footage, which includes what happens when you start prototyping with your Speed Racer dolls.
NZXT's Cryo E40 laptop cooler sends a pleasant breeze wherever you like
NZXT is pretty good when it comes to avoiding unnecessary flourishes and providing straight-up PC hardware. Its Cryo E40 laptop cooler is no different, forgoing HDD slots and magic elixirs in favor of two 80mm fans that clasp magnetically to the underside of its steel mesh. These can be plucked off and moved around to suit your lappie's particular hotspots -- so long as you're using a 15-incher or smaller. The E40 rises to 60mm above the surface of your desk, covers an area 420mm wide by 300mm deep, and is powered via a USB cable that can also be shifted to the left or right to suit your ports. The price of all this flexibility? That'd be $28, please, with availability from next month.
Nokia Morph patent application raises hope well beyond expectation
Remember Nokia Morph? It's the Finnish manufacturer's long-standing project to build a transparent, flexible phone that you can contort to your hearts content. Now the company's submitting a second missive to the Patent and Trademark office in the hope of claiming dibs on the IP contained therein. While it's very broadly written (and doesn't commit to anything), it's interesting to note that the phone would switch between the leaf-shaped candybar (we played with it at MWC) and a wristband you can wear on the go. The patent also talks about a "remote processing unit," in a nearby device or in the cloud, so, if the company can ever turn the dream into reality, the real action will be handled elsewhere. Then again, it's equally as likely to never appear in our lifetimes, you just never can tell with patents.
Cambridge researchers translate graphene into printable circuitry material, bring basic 'Skynet' factory to you
Yes, graphene is amazing and possesses many useful / otherworldly properties. The ability to use graphene itself to print flexible, transparent thin-film transistors via an inkjet printer is just another one of them. Over at the University of Cambridge, researchers have discovered that it's possible to print standard CMOS transistors using a graphene component. Provided the graphene is chipped off a block of graphite using a chemical solvent and the larger (potentially print-head blocking) chips are removed, it can be turned into a polymer ink which can then run through a conventional inkjet printer. The potential result of this is flexible, transparent and wearable computer circuitry coming from ordinary printers as opposed to several multi-million-dollar machines in a factory, which has long been the historical standard. Besides, who wouldn't want to print their own circuitry on a PhotoSmart MFP rather than whatever report might be due the next day?
Nokia's Humanform concept phone, not shaped like us (video)
We barely recovered from Nokia's futuristic concept buffet at Nokia World, but a new video has unearthed the deceptively named Humanform. Fortunately not shaped like a dolly, this teardrop device cooked up Nokia's in-house labs supposedly uses some as-yet unexplained nanotechnology, with a bendable transparent display and a fully touch sensitive casing. The segmented design also channels some Wiimote-esque gesture features and twist controls seen on the phone behemoth's Kinetic Device. An inert Humanform shell was also on show alongside it last month, although it didn't do much aside from bending. See if you agree with Nokia's vision of the mobile future after the break.
Korean bendy memory could make plenty of trendy tech
Flexible displays aren't much good unless there's flexible memory alongside. It's been attempted before, but bending memory pushes the individual transistors so close that they begin to interfere with one another -- causing degradation and shortening the device lifespan to just a single day. The Korea Advanced Institute of Science and Technology (KAIST) has solved the problem by pairing transistors with memristors, which are immune to such annoyances. By fixing both inside a flexible substrate, you can push them as near as you like without any electo-radiation spanners jamming up the works. This also means that the flexible RRAM behaves just like flash memory; maybe in the future it won't just be antennas sewn into our clothes.
Warhammer 40K planning multiple payment options
Despite being one of THQ's biggest projects, the upcoming Warhammer 40,000: Dark Millennium Online won't be hemmed in with a single subscription option. Instead, the company said that it is investigating a wide range of possible payment options to be as flexible as possible for players all over the world. Speaking at a recent earnings call, CEO Brian Farrell addressed what model WAR40K would adopt. "What we've done is make the business model within Dark Millennium Online flexible so we can use different business models in different territories and exploit the game on a worldwide basis," he said. "We will have not just one business model, like subscriptions. There will be other monetisation mechanisms in the game... The team there is being very thoughtful about how we maximise monetisation in this game." Seeing as how WAR40K is costing the company over $50 million to create, it seems wise to offer multiple options in order to draw in the largest amount of players possible. The title is being developed by Vigil Games and is slated to release in 2013.
Nokia's kinetic future: flexible screens and a twisted interface (video)
Hidden within Nokia's Future Lounge, this very flexible display offers up a glimpse of what sort of thing we could possibly be dealing with when we roll up to Nokia World in 2021. The prototype Nokia Kinetic Device, including its display, can be flexed across both the vertical and horizontal planes -- with bending and twisting motions controlling the interface. If you bend the screen towards yourself, it acts as a selection function, or zooms in on any pictures you're viewing. In music mode, you can navigate, play and pause with the tactile interface. It's still a way off from arriving on phones, though Nokia is aiming to whet developers' appetites with this prototype. We may have seen some twisty interfaces already, but nothing packing a four-inch screen and built-in functionality like this. Nokia couldn't confirm the screen technology being used. Could that be a flexible AMOLED display? See those impressive viewing angles and contortions after the break and judge for yourself.%Gallery-137602%
Murata Tactile Controller TV remote hands-on (video)
What's that, you're not into changing the channel with that boring old remote, or even with your voice? Murata's ground-up Tactile Controller brings a real twist to every couch potato's favorite gadget. Quite literally. The company's prototype remote uses touch-pressure pads and pyroelectricity to analyze the position of a piezoelectric film. In English: a plastic film produces tiny amounts of electricity at various voltages (output as data) when it's forced into a variety of positions, letting you change the channel simply by twisting the controller in either direction, or flexing to adjust volume. The model we saw was a plastic sandwich of sorts, and also included four solar cells, capable of producing one milliwatt of electricity -- just enough to power the device. We put the controller through its paces at the company's CEATEC booth, adjusting a TV's volume and channel up and down, and, well, up and down, since that's just about all you can do with the thing. The model we saw only supported five twist positions and four bending positions in each direction, so it could theoretically adjust those two basic settings more quickly based on how much pressure you put on the film, but realistically can't do much beyond that. The Tactile Controller on display here is more of a proof of concept of sorts -- with the concept being the plastic film technology itself, and not the battery-free remote control, which the company decided would be the most visual application for testing its new film, though not necessarily the most practical. Understandably, Murata doesn't have any plans to release the remote that we saw today, but you can jump past this to see us do the twist.%Gallery-135771%
Murata wants to take couch potatoes by the hand and do the remote control twist
We've seen Murata's marketing future, and it involves either Chubby Checker or that '90s Helen Hunt movie. The Japanese electronics maker's cooked up a flexible sensor device that'll let you twist and shout bend your way to remote television control. Dubbed the Leaf Grip Remote Controller, the prototype UI design makes use of a special pyroelectric effect-free piezoelectric film that translates twisting into channel changing, rapid twisting to swap video inputs, bending for volume control and rapid bending to power the set on / off. The company's also outfitted the non-clicker (which we'll henceforth refer to as "the Twister") with a photovoltaic cell, giving it the ability to charge -- from your man cave? Kinks in its planning aside, sample shipments are expected to be delivered sometime next spring. But, before they rush this product out to market, may we suggest the inclusion of a sports-induced rage-proof mode?
Polymer Vision drops the ball on its flexible display, literally
Flexible displays may well be the future, but it's not hard to see that they won't truly be practical unless they're also as durable as they are flexible. Polymer Vision is well aware of that fact, of course, and it's now gone to some "extreme" lengths to demonstrate the progress it's made on that front. See the results for yourself in the video above.
Engadget Primed: all mobile displays are not created equal
Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com. The quality of a mobile phone's display is arguably the most important factor to consider when you establish a relationship with a handset. It's inescapable, really. Whether you're playing a rousing game of Robot Unicorn Attack or (regrettably) drunk-dialing an ex, it's the one interface element that you're consistently interacting with. It's your window to the world and your canvas for creation, and if it's lousy, it's going to negatively influence everything you see and do. Today, we're delving into the world of mobile displays, where we're aiming to entertain and edify, and hopefully save you from making regrettable decisions -- when it comes to purchasing new phones, anyway. In this edition of Primed, we'll be examining the different qualities and underlying technologies of several displays, starting with the ubiquitous TFT-LCD and moving through the nascent realm of glasses-free 3D and beyond. We'll also be addressing the importance of resolution and pixel density. Finally, we'll be scoping out a handful of upcoming technologies -- while some are thoroughly intriguing, others are just plain wacky. Go ahead... buy the ticket, take the ride, and join us after the break. It's Primed time.
MIT researchers revolutionize solar cell printing, fold the power of the sun into your everyday home (video)
Wouldn't it be neat if you could power a few gadgets around the house with some tastefully chosen, solar cell-embedded curtains? Alright, so this MIT-pioneered tech's not quite that advanced yet, but it's destined to have a Martha Stewart Living future. By eschewing liquids and high temperatures for gentler vapors kept below 120 degrees Celsius, researchers were able to cheaply print an array of photovoltaic cells on "ordinary untreated paper, cloth or plastic." And here's some additional food for thought -- the vapor-deposition process used to create these cells is the same as the one that puts that "silvery lining in your bag of potato chips" -- science, it's everywhere. Despite the tech's home furnishing friendly approach, this breakthrough printing technique can't be done with your everyday inkjet, but it will make the cost of solar energy installations a bit cozier. Its flexible durability aside, the cells currently operate at only one percent efficiency -- so you might want to buy those drapes in bulk to see a real bottom line kickback. Foldable paper video demonstration after the break.
Samsung to finally roll out flexible AMOLED displays for public consumption in 2012?
Samsung's been a frequent source of frustration, teasing us with its fabulous flexible displays for years, while never giving us a date when we could buy one for our very own. However, word on the web suggests that Sammy is finally ready to unleash its pliant panels upon the world in Q2 of 2012. Apparently, the company's mobile display division opened a new manufacturing plant with Ube (who produces the plastic substrate for the screens) last month to mass-produce bendy AMOLEDs for watches and phones. Let the countdown to the ductile display revolution begin.
Conductive nanocoating could lead to flexible, wearable devices, Lady Gaga sticks with meat suit
Flexible is the new rigid in the gadget world, from OLED panels and e-paper displays to, of course, the adorable PaperPhone. Now researchers at North Carolina State University are hoping to take flexible to the next level by applying a conductive nanocoating – thousands of times thinner than a human hair – to ordinary textiles. Their technique, called atomic layer deposition, grows an inorganic coating atop cloths like woven cotton. The treated fabric conducts electricity, opening the door to thin, wearable devices with the flexibility of everyday clothing. The technology's still in its nano-infancy, but who knows: maybe a few years from now you'll be sporting a genuinely playable Angry Birds shirt.
