Bionic finger makes amputee feel texture on his phantom hand
Someday, amputees might be able to get prosthetics that can discern shapes and feel texture, thanks to the Swiss Federal Institute of Technology in Lausanne (EPFL). Its scientists have succeeded in designing a bionic fingertip (PDF) that can make amputees feel textures and even differentiate between rough and smooth surfaces. The team asked Dennis Aabo Sørensen, who lost his left hand in an accident, to test it out. He said the sensations it gave him were almost like what you'd feel with your own hand.
