From Engadget that links to the story above...
A team of researchers from the Tokyo Institute of Technology (TIT) claim to have developed the world’s first electromechanical prosthetic hand with a grip strong enough to crush an empty beverage can.
This bionic hand weighs a little more than 300 grams and has a grip strength of around 15 kg (33 lbs), which is about half that of the average adult male. The hand also features four quick, nimble fingers that take as little as 1 second to flex and extend. When used in combination with the hand’s opposable thumb, each finger can deftly pinch and pick up small objects of various shapes.
