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.
UCLA / Caltech researchers help patients move mouse cursors with their brains
It's certainly not a revolutionary new concept -- whiz kids have been tinkering with brain-controlled interfaces for years on end -- but a collaboration between UCLA scientists and colleagues from the California Institute of Technology has taken the idea one leap closer to commercialization. Itzhak Fried, a professor of neurosurgery at UCLA, kept a close watch (via embedded electrodes) on how a dozen humans reacted to certain images, and eventually, Fried and co. were able to show that Earthlings can "regulate the activity of their neurons to intentionally alter the outcome of stimulation." In other words, they were able to move a mouse cursor with just their mind, and brighten a test image with a 70 percent success rate. By honing the process of controlling what actions occur when focused on a given subject (or input peripheral), it opens up the possibility for paralyzed individuals to not only check their email, but also control prosthetic limbs. It's hard to say when this stuff will be put to good use outside of a hospital, but the video after the break definitely makes us long for "sooner" rather than "later."
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.

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.
Touch Bionics i-LIMB Pulse, the Bluetooth bionic hand, makes your meaty one obsolete
Let's say you got in a fight with your dad. You said some things, he said some things, and then he cut your hand off. Don't go all emo: Touch Bionics has a new product that will have you overthrowing empires again in no time. A successor to the company's revolutionary i-LIMB Hand, the i-LIMB Pulse is a more streamlined version meant to look more natural, also offered in two sizes, and comes complete with Bluetooth that allows prosthetists and users to tweak settings easily. The device's name comes from its "pulsing technology" that boosts strength, enabling it to handle up to 90kg (about 200lbs), which is a lot more than our crippled carpal tunnels can manage these days. The Pulse starts shipping to would-be chosen ones on June 1 -- just in time for Father's Day. %Gallery-92450%
Energy-recycling foot makes it easier for amputees to walk
What's better than an artificial nose? Why, an artificial foot, of course! University of Michigan researchers have developed a new prosthetic foot that could one day make it much easier for amputees to walk. Put simply, this new prototype drastically cuts the energy spent per step, as it harnesses the energy exerted when taking a step and enhances the power of ankle push-off. The device is able to capture dissipated energy, and an inbuilt microcontroller tells the foot to return the energy to the system at precisely the right time. Tests have shown that those using this here foot spent just 14 percent more energy to walk than one would spend when walking naturally, which is a rather significant decrease from the 23 percent uptick experienced with conventional prostheses. If you're still baffled, there's a pretty wicked video demonstration waiting for you after the break. %Gallery-86121%
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.

EU scientists develop LifeHand thought-controlled prosthesis
We've seen plenty of developments in neurology and robotics over the years, including the Smart Hand prosthesis and targeted muscle reinnervation, and now researchers at the Bio-Medical Campus University of Rome have announced LifeHand. Connected via electrodes to an amputee named Pierpaolo Petruzziello, the device is able to perform complex movements and is controlled by thought alone. "It's a matter of mind, of concentration," said Petruzziello. "When you think of it as your hand and forearm, it all becomes easier." The five year project, funded to the tune of about $3 million by the European Union, is just the beginning -- they still have to figure out how to make the implants permanent. Get a closer look below.
Video: doctors implant tooth into eye, restore sight, creep everyone out
Osteo-odonto-keratoprosthesis. It's a real procedure that really does revive people's ability to see, yet we get the feeling that people will be more, um, excited about how it's done than why it's done. The seemingly Mary Shelley-inspired doctors extract a tooth from a blind person and drill a hole through it, where a prosthetic lens is placed, and the resulting macabre construction is implanted into the blind person's eye. The tooth is necessary as the body would reject an artificial base. It's not at all pretty, and it cannot repair every type of blindness, but it's still a major step forward. To hear from Sharron Thornton, the first American to have undergone the procedure, check the video after the break, but only if you can handle mildly graphic content -- you've been warned.

Brain Carpet microelectrodes could help translate thoughts into actions more effectively
Researchers at the University of Utah have developed a new, more precise way of placing microelectrodes on the surface of the brain to enable patients to turn thoughts into action. Led by Bradley Greger, a professor of bioengineering, the "Brain Carpet" as it's called, represents a "modest advance" in techniques already in use. The Brain Carpet makes use of smaller microelectrodes, and also employs many more than are usually used. The method involves sawing off the skull of the patient, then placing 32 electrodes about 2mm apart on the surface of the brain. Though they've conducted tests on just a handful of patients -- all epileptics -- the technique, they believe could also be used to help people control their prosthetic limbs much more effectively. The electrodes allow detection of the electric signals in the brain which control arm and hand movements. In the tests, patients have successfully controlled a cursor on a computer screen following the operation, and they see applications for brain-machine interface devices in the future. There's no word on when the Brain Carpet will move from the research to reality phase, but the group's findings have just recently appeared in the journal Neurosurgical Focus.
Ossur's new POWER KNEE prosthesis sports A.I., motorized actuators
Perhaps it's a sobering reminder of the world we live in, but we've seen prosthetic technology grow in leaps and bounds over the last couple years. Continuing the upward arc, Ossur has just announced its second generation POWER KNEE device. Developed in partnership with Victhom Human Bionics, the device is billed as "the world's first and only motor-powered, artificially intelligent prosthesis for above-knee amputees." Features include: advanced torque and accelerometer sensors that keep an eye on the ground level and compensate accordingly; actuators that actively lift and stimulate the users own muscles for walking up stairs, inclines and ramps; and what the company is calling its "artificial intelligence" features, which allow the device to "observe the whole state of the respective human-system interface." Currently in use at Walter Reed Army Medical Center, a full commercial release is expected by 2010.
USB finger drive concept attempts to keep up with reality
Yanko Design is certainly home to many far-fetched, never-to-be-realized gadgets, but this so-called You-SB finger drive isn't one of them. In fact, it's already a bit behind the curve. Apparently, after losing a finger in a motorcycle accident last year, Jerry Jalava took advantage of the situation to get a 2GB USB drive installed in his new prosthetic finger, which he's happy to inform us stores the Billy Linux distribution and the movie Freddy Got Fingered. The drive is even removable to allow for upgrades or different drives for different tasks. Can a pico-projector finger be far behind?Read - Yanko Design, "You-SB"Read - Jerry Jalava's Flickr page[Via Grinding.be]
DIY prosthesis all the rage in Tasmania
When the doctors told amputee Mark Lesek that the severity of his injury made him ineligible for a prosthesis, he refused to give up. Left with nothing but his own welding and engineering business, several hundred thousands of dollars, and an indomitable spirit, the Tasmanian gentleman began the quest for an artificial arm. First, he shopped around until he found a doctor who agreed to order an $80,000 prosthesis from Germany -- which eventually broke down (but not before he shelled out $6,000 for repairs on the thing). His next stop was the Branemark Osseointegration Centre in Sweden, where he was fitted with an $80,000 bolt that works as a sort of "artificial shoulder." Still unable to find a suitable arm, the guy teamed up with one of his employees to design and build his own lightweight magnesium "body powered" prosthesis. But that's not all -- he's also working with the University of Tasmania to develop a more agile computer-controlled arm, controlled with "a cap with electrodes which will be interfaced into the computer." Let's hope that all his hard work pays off -- and that he teaches those doctors a thing or two in the process.[Via Switched]
Immaculate prosthetic limb concept makes combines fun again
We never thought it would it come to this, but damn if that image above doesn't make the idea of having a prosthetic limb attractive. A pang first felt at the sight of Oscar Pistorius' Cheetah prosthetics is now fully engorged with visions of reckless play around farm equipment. The concept "immaculate" from Hans Alexander Huseklepp explores the idea of turning a handicap into a high-performance, cybernetic fashion statement. The neurological prosthetic is clad in technology-packed corian plates with dome-joints that offer a larger degree of freedom than that motherly-issued arm of yours. So enough with the flesh-colored plastics already, this is the biomechatronic future of the proud naturoid we'd like to see. Hell, we have to do something now that tattoos and piercings have gone mainstream.
