The artificial hand picks up electrical signals from artificial tendons controlling the movement of its fingers, which are sent down fine wires to four electrodes implanted in sensory nerves in the upper arm. This is the first time in neuroprosthetics that sensory feedback has been restored and used by an amputee in real-time to control an artificial limb, said Silvestro Micera, of the Federal Polytechnic School of Lausanne, Switzerland, who leads the Life Hand 2 project. Dennis Sorensen, from Denmark, felt the shape and texture of objects during a months trial in Rome of the robotic hand developed by Swiss and Italian scientists. The sensory feedback was incredible, said the 36-year-old, whose experience may help pave the way for artificial feeling limbs. When I held an object I could feel if it was soft or hard, round or square. theguardian/science/2014/feb/05/bionic-hand-limb-sense-touch-artificial?CMP=fb_gu
