  • For the first time, a person who lost his hand has had a near-natural sense of touch restored thanks to a prosthesis that delivers electrical signals straight to individual nerves. The approach is the most significant step yet on the road to creating prostheses that feel indistinguishable from real limbs. Dennis Aabo Sorensen, who used the prosthesis for six weeks, says the feeling is very close to the sensation he gets when he touches things with his normal hand. To restore Sorensen's sense of touch, Silvestro Micera at the Swiss Federal Institute of Technology in Lausanne and his colleagues implanted tiny electrodes inside the ulnar and median nerve bundles in Sorensen's upper arm.
