British man's prosthetic arm doubles as Nokia C7 dock
Smartphones have changed our lives, sure, but for those with only one arm, the touchscreen-centric devices can be a downright nuisance. Trevor Prideaux of Somerset, England has worked out of a solution, with help from Nokia and some folks in the medical community. A prosthetist built the 50-year-old catering manager a limb with a cradle for his Nokia C7, allowing Prideaux to operate the phone with a single hand. Prideaux told The Telegraph that he'd initially approached Apple for assistance with the project, eventually settling on Nokia after the Finnish handset maker agreed to help out.

Eyeborg filmmaker fires up eye-cam to document cutting edge prosthetics (video)
In late 2008 filmmaker Rob Spence, caught our attention when he announced his plan to jam a video camera in his skull to replace an eye he lost to an unfortunate accident. Instead of connecting the camera to his brain, Spence sought to become a so-called "lifecaster," recording the feed on an external device. Now his bionic eye is up and running, and he's even partnered with a little company called Square Enix to create a documentary about state-of-the-art prosthetics and cybernetics. The short film, embedded after the break, was commissioned to celebrate the launch of Deus Ex: Human Revolution. But, this isn't just some over-long commercial for a game, it's a serious exploration of cutting-edge leg, arm, and eye replacement technology. Check it out below, but be warned -- there are a few images that might not sit well with weaker stomachs.
Bionic leg anticipates wearer's movements for more natural motion
Vanderbilt University researchers have debuted a new prosthetic leg that promises a more natural walking experience. Built-in sensors monitor the wearer's movement, data which is sent to a microprocessor, in order anticipate motion. The knee and ankle joints, meanwhile, work in unison, considerably cutting down on the sort of lag this is customary with more traditional prosthetic devices, a fact confirmed by tester Craig Hutto. The bionic limb, which took some seven years to develop, can increase the walking speed of its wearer by up to 25 percent, thanks to its need for considerably less energy from the user than passive prosthetic limbs. Check out a video of the leg in action at the source link below.
BBC shows us what it's like to live with a bionic hand
We've posted a fair share on bionic limbs and their advancements over the years, but rarely have we had the chance to see a video of one in real world use, on a real person. The BBC has shared a video of a man named Patrick using his bionic arm, which -- long story short -- was partially the result of being electrocuted at work. This is his second one to date and specifically, it's a prototype Otto Bock mind-controlled prosthetic arm equipped with six nerve sensors that let him use the hand as if it were his own -- it supports pinching and gripping with the fingers as well as lateral and circular movement of the wrist. Although the footage is a mundane roll of various day to day tasks -- gripping a bottle to pour a glass of water for instance -- it's quite amazing to realize technology is helping him do things he'd otherwise be deprived of. We'd suggest checking it out at the BBC by clicking the source link below.
Researchers take one step closer to neural-controlled bionic legs for safer mobility
We've seen our fair share of prosthetic arms and computer interfaces operated with little more than the firing of a synapse, but legs? They're a different story: balancing and propelling a sack of (mostly) flesh and bone is a much more complicated task than simply picking up a sandwich. Thankfully, the Rehabilitation Institute of Chicago's Center for Bionic Medicine is now one step closer to thought-controlled lower-limb prosthetics. As pictured here, the researchers' early simulations showed that amputees could control a virtual knee and ankle with 91-percent accuracy, by way of pattern recognition software to interpret electrical signals delivered through nine different muscles in the thigh -- patients think about moving, thus lighting up the nerves in varying patterns to indicate different motions. The ultimate goal is to hook up bionic legs through the same way, which would offer a greater range of motion than existing prosthetics, making tasks like walking up and down stairs safer. Now all we need is a quadruple amputee willing to pick up a badge and slap on an eye-tracking microdisplay.
AMO Arm pneumatic prosthetic does mind-control on the cheap
We're no strangers to amputees moving stuff with their minds -- for that matter, a thought-controlled prosthetic isn't really new to us, either -- but the pneumatic arm you see here isn't like other intelligent limbs. Unlike most mind-operated prosthesis, the Artificial Muscle-Operated (AMO) Arm doesn't require invasive surgery, and according to its inventors, it costs a quarter of the price to make. Here's how the thing works: the host human wears a headset that sends brain signals to a chip in the arm that then matches those signals to a database of related actions, triggering a series of pneumatic pumps and valves to move the limb. Thus, if the wearer thinks 'up,' the arm moves up. The AMO Arm's creators, a pair of undergraduate biomed students, say that not only is their invention a steal to produce, but it also takes just minutes to acclimate to, which has us wondering, do you have to be missing an arm to get a hold of one of these things? You know, we can always use an extra hand. Full PR after the break.
Power Knee motorized prosthetic officially available in US, Europe -- race of cyborgs still in infancy
We reported on Ossur's robotic prosthetic back in 2009, and now amputees in Europe and the United States have become the first official recipients of the Power Knee. According to the company, "the world's first and only motor-powered prosthetic knee" was recently approved for reimbursement by the German National Health System, covered by private insurance in France and the UK, and picked up by select healthcare providers in the US. Power Knee combines "artificial intelligence," motion sensors, and wireless communication to learn and adjust to the walking style of its users -- that's one small step for real-life cyborgs and one giant leap for prosthetic technology.
Dean Kamen unveils revamped bionic arm and water machine, LED light bulb powered by Cree
Segway inventor Dean Kamen just stole the show at TEDMED 2010, with both a far-reaching lecture on how technology can save the developing world, and a peek at his latest projects. We'll spare you the wave of guilt for now and get right to the cool stuff, like the latest rendition of his Luke prosthetic arm and Slingshot water machine. Dean admitted he's having difficulty finding companies interested in manufacturing the former, but it's looking snazzier than when it last grabbed Stephen Colbert, with components like this shoulder piece printed out of titanium in a custom 3D printer, and it's slated to look like this. The Slingshot's seeing even more action, as Dean and company have pulled it out of the ugly box into these svelte tubes, and finally has a distribution deal (with Coca-Cola, of all companies) to bring the clean-water-from-any-source machines to developing countries in trials early next year. Last but not least, the man's got a product you might be able to afford for your home. In the quest for an item for his FIRST young engineers to sell -- a la Girl Scout cookies -- he tapped LED manufacturer Cree to produce an 450 lumen light bulb that draws just 7 watts and will retail for about $25 door-to-door. In case you're wondering, that's cheaper and more efficient than most any lamp we've seen before. Dean says they've already produced several hundred thousand of the bulbs thanks to a surprise $3 million investment from Google, and plan to have them in the hands of every FIRST kid soon. Keep on fighting the good fight, Dean. %Gallery-106215%
Man with bionic arms dies after car crash
Otto Bock's mind-controlled bionic arms let Austria's Christian Kandlbauer work, play and even drive, but it seems the latter passion may have lead to the 22-year-old's untimely demise. Two days after a road accident where the young man's specially-modified Subaru crashed into a tree, Kandlbauer was pronounced brain-dead and taken off life support late last week. It's not known whether the prosthetic arms themselves had anything to do with the crash -- one was found ripped from his body at the scene -- but both he and his vehicle were cleared to drive by local authorities after passing a number of tests. Honestly, it's a tragedy for science and humanity either way.
SMU and DARPA develop fiber optics for the human nervous system
The Department of Defense and Southern Methodist University have teamed up to develop prosthetics that use two-way fiber optic communication between artificial limbs and peripheral nerves to essentially give these devices the ability to feel pressure or temperature. The technology is called neurophotonics, and it will someday allow hi-speed communication between the brain and artificial limbs. But that's just the beginning -- the work being done at SMU's Neurophotonics Research Center might someday lead to brain implants that control tremors, neuro-modulators for chronic pain management, implants for treating spinal cord injuries, and more. And since we can't have a post about DARPA-funded research without the following trope, Dean Orsak of the SMU Lyle School of Engineering points out that "[s]cience fiction writers have long imagined the day when the understanding and intuition of the human brain could be enhanced by the lightning speed of computing technologies. With this remarkable research initiative, we are truly beginning a journey into the future that will provide immeasurable benefits to humanity." Truly.
UC Berkeley researchers craft ultra-sensitive artificial skin, robots dream of holding eggs
Researchers and engineers have been toiling on synthetic skins for years now, but most of 'em have run into one major problem: the fact that organic materials are poor semiconductors. In other words, older skins have required high levels of power to operate, and those using inorganic materials have traditionally been too fragile for use on prosthetics. Thanks to a team of researchers at UC Berkeley, though, we're looking at a new "pressure-sensitive electronic material from semiconductor nanowires." The new 'e-skin' is supposedly the first material made out of inorganic single crystalline semiconductors, and at least in theory, it could be widely used in at least two applications. First off, robots could use this skin to accurately determine how much force should be applied (or not applied, as the case may be) to hold a given object. Secondly, this skin could give touch back to those with artificial hands and limbs, though that would first require "significant advances in the integration of electronic sensors with the human nervous system. Dollars to donuts this gets tested on the gridiron when UCLA and / or Stanford comes to town.
New prosthesis sends feedback to the brain, might alleviate phantom pain
Even as prosthetic technology advances, the problem of phantom limb sensation persists. Essentially pain, pressure, or some other stimulus attributed by the brain to a limb that has been lost, the exact cause for this is unknown -- and it's a very real problem for amputees. Hoping to better understand (and someday maybe eliminate) the phenomenon, researchers at the University of Jena in Germany have developed a prosthesis that uses sensors and a stimulation unit to send feedback from the patient's artificial hand back to the brain, offering some relief to the individual in the process. So far, the team has had some success, but as the school's Dr. Thomas Weiss points out, there is quite a bit of work yet to be done to determine if "the hand is helpful to only a few people or if it is a therapeutic for all wearers of artificial limbs."
DARPA-funded prosthetic arm reaches phase three, would-be cyborgs celebrate
Last we heard from Johns Hopkins University's Applied Physics Laboratory, it wanted a neurally-controlled bionic arm by 2009. Needless to say, the school overshot that goal by a tiny bit, and have now been beaten (twice) to the punch. But DARPA sees $34.5 million worth of promise in their third and final prototype, which will enable the nine pound kit (with 22 degrees of freedom and sensory feedback) to begin clinical trials. Rechristened the Modular Prosthetic Limb, it will be grafted onto as many as five real, live persons, the first within the year. Using the targeted muscle reinnervation technique pioneered at the Rehabilitation Institute of Chicago, patients will control these arms directly with their thoughts, and for their sakes and the fate of humanity, hopefully not the other way around. Press release after the break.
Amputee cat gets bionic back legs and a new attitude
When Oscar the cat got both of his back legs severed by a harvester, his prognosis was undoubtedly grim. Luckily for him, he was referred to a veterinarian, Noel Fitzpatrick, who had some pretty interesting ideas of his own. Dr. Fitzpatrick has successfully given the cat two back prosthetic legs, but they're completely unlike any prosthetic we've ever seen. Oscar's been given Itaps (intraosseous transcutaneous amputation prosthetics) which were developed at University College London. Itaps are custom made pegs which allow the bone and skin to grow to them, meaning that the "prosthetic" actually becomes part of the appendage itself. The surgery has been in testing for humans since 2005, and this one was the first performed on an animal. Hit up the BBC source link to check out a video of the kitty getting mobile.
BeBionic officially unveils its incredible myo-electric bionic hand
Back in February when we first caught wind of BeBionic's myo-electric, very realistic bionic hand, we were quite impressed. The finished product was just unveiled at ISPO World Congress in Leipzig Germany, and it's looking even better than our first glimpse gave away. We don't know a ton more about how the hand functions -- it boasts a fully integrated wireless chip, fully customizable functions to control speed, grip force, and grip patterns, plus aesthetic bonuses such as silicone skin overlays in 19 different tones. The BeBionic hand is now due for worldwide distribution in June of this year -- but check out the teaser video below if you're still curious.
Mind-controlled prosthetic arm moving to market in Europe
Germany-based Otto Bock Healthcare has announced that its prototype prosthetic arm which can be controlled by thought is ready to hit the market. The device has been in testing on Christian Kandlbauer -- who doesn't have any arms and has a conventional prosthetic on his right side -- for the past four years. He's the first person in Europe to have a thought-controlled prosthesis installed, but the research is complete and the finished product should soon be available to the public. The arm makes use of targeted muscle reinnervation (TMR), which uses nerves that controlled the lost arm to control the prosthesis. The nerves are transplanted to the chest in a six-hour operation and enable the prosthetic control. The full details of the arm's operation and controls have yet to be unveiled, but hit up the source link for more information.
Dean Kamen shows off his prosthetic arm on The Colbert Report
Dean Kamen showed up on The Colbert Report last night to show off Luke -- the advanced prosthetic arm he's been working on with DARPA and the Defense Department for the past few years. Besides the requisite Segway jokes (and Colbert's are pretty funny, we'll give him that), it's pretty heart-warming to see Kamen and his crazy awesome arm hanging out with our favorite faux Republican. Just more proof that Colbert is a major gadget nerd. The video's after the break -- hit the read link if you want to watch the entire episode.
BeBionic teases advanced bionic hand, Terminator 5 now has a prop supplier (video)
It won't officially launch until May, but we're already guessing that the folks over at DaVinci are casting quizzical glances towards BeBionic. The UK-based outfit is teasing what it calls the "next generation of fully articulated myo-electric hands," which are said to provide "a range of naturally compliant grip patterns that provide repeatable accuracy" to those who have lost their own hand(s). Better still, the functions (speed, grip force, grip patterns, etc.) can be customized to suit each individual user, and the integrated wireless chip means that said tweaking can take place sans any troubling USB cables. The company's also planning to reveal the planet's first powered wrist with rotation capabilities as well as flexion / extension, and the range just wouldn't be complete without silicone skin available in 19 tones. Hop on past the break for a couple of promo videos -- we get the feeling the world of prosthetics is about to take a huge leap forward.
Artificial muscles let cadavers (and someday paralyzed humans) wink with the best of 'em
The above contraption, aside from looking really uncomfortable, is the latest advance in electroactive polymer artificial muscle technology. Using soft acrylic or silicon layered with carbon grease, EPAMs contract like muscle tissue when current is applied -- making 'em just the ticket for use in UC Davis's Eyelid Sling. Billed as the "first-wave use of artificial muscle in any biological system," the device is currently letting cadavers (and, eventually paralyzed humans) blink -- an improvement over current solutions for the non-blinking, which include either transplanting a leg muscle into the face or suturing a small gold weight into the eyelid. Look for the technology to become available for patients within the next five years.
Touch Bionics offers ProDigits for those missing their amateur ones
Touch Bionics has been at this bionic prosthetics business for a while now, already providing i-Limb solutions to those deprived of the use of their hands or arms. The company's latest innovation is to reduce all that tech down to the level of individual fingers, with its freshly announced ProDigits being able to replace anywhere between one and all of your precious little piggies. Relying on a traditional myoelectric regime -- which reacts to muscle signals from the residual hand -- or pressure from the remnant finger for its input, this invention can even be tweaked by doctors (over Bluetooth) to adjust the finer motor functions on a per patient basis. Costing up to £40,000 ($65,000), these new prosthetics will be custom-built for each person, and there are plans to apply to have them made available through national health insurance -- in countries that are into that sort of thing. Video after the break.
