Clever Artificial Hand Developed
AccUser writes "The BBC is reporting that scientists have developed an ultra-light limb that they claim can mimic the movement in a real hand better than any currently available. Researcher Dr Paul Chappell, a medical physicist who worked on the device, said, 'With this hand you can clutch objects such as a ball, you can move the thumb out to one side and grip objects with the index finger in the way you do when opening a lock with a key, and you can wrap your fingers around an object in what we call the power grip - like the one you use when you hold a hammer or a microphone.'"
It's not the hand, or motor/servo, or interface that needs improving, it's the Power Source ! Without long-lasting (much better than iPod!) batteries, this technology will go nowhere. I did research in prosthetics back in '75 and won quite a few awards and acclaim for the work, but had the same problem. One solution that was presented back then, but not much work has been done on it since, is a blood-powered fuel cell. It is implanted in the body and derives power from sugar and oxygen. Next best thing would be a pee-powered battery (grin).
Chaos maximizes locally around me.
