A Mind Controlled Arm

Otto Bock Healthcare, has developed a mind-controlled technology, which is ready to leave the laboratory and be put to everyday use. It involves a new technique known as targeted muscle reinnervation (TMR), where nerves that once controlled a lost limb are used to control a prosthesis. The transplanted nerves allow electrical impulses from the brain to reach the muscles in the chest. The muscles act like a booster, amplifying the signal to a level that can be picked up by electrodes on the surface of the chest. These signals are interpreted by a micro-computer, and used to control a prosthesis which responds in real time to thoughts from the brain.
