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%
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]
Dean Kamen's "Luke" artificial arm gets demoed on video
It's still awaiting formal clinical trials, but Dean Kamen's so-called "Luke" artificial arm has already gone through its share of tests, which we can now thankfully catch a glimpse of courtesy of a new video from the folks at IEEE Spectrum Online. That same video also helpfully provides a few more details on the arm, including word that it can be controlled through a variety of means including foot pedals, nerves or muscles, and that it packs force feedback to give the wearer an indication of grip strength, among other suitably sci-fi-like things. Of course, none of this exactly does the arm justice, so be sure to check out the video at the read link below to see it in action for yourself.[Thanks, Sarah]
First woman gets bionic arm
As The Washington Post reports, 26-year old Claudia Mitchell has become the fourth person and first woman to get outfitted with a bionic arm (well, besides Lindsay Wagner), with which she's able to perform functions simply by thinking about them. The arm was designed by researchers at the Rehabilitation Institute of Chicago -- who are part of a larger project funded by DARPA -- and works by detecting the movement's of Mitchell's chest muscle, which has been rewired to the nerves that once served her left arm. Eventually, researchers say, the arm could even give Mitchell the sense of touch, with electrodes in the hand sending signals to her chest skin, which her brain would recognize as a sensation. This being part of a DARPA project though, we're sure they're also working on things they're not telling us, like crazy swinging grappling hook action.[Thanks, Spluch]
