bebionic has just released this promotional video showing off its next generation of fully articulated myo-electric prosthetic hands, due to launch in May 2010.
Being myo-electric, as opposed to cable operated, means that the prosthesis can be moved in accordance with the muscles of the upper arm. When the muscle is contracted the bebionic hand picks up the electrical signal (EMG) via electrodes attached to the skin.
The blurb on the bebionic site reads "complete with a range of naturally compliant grip patterns that provide repeatable accuracy, our powerful new hands combine innovative technology with life-like appearance".
In the video the hand is shown carrying out tasks such as pulling out a Twenga brick and picking up a small ball using just thumb and forefinger, leading us to believe that the hand is pretty dexterous.
Thanks Dave for the tip.
