Vivsa electrodes in the nerves, researchers can electrically stimulate them.
Swedish scientists first connected the prosthetic hand directly to the nerves, allowing him to move your fingers with your mind and even experience tactile sensation. Said this yesterday, the website of Naked Science.
Researchers from the Technological University of Chalmers in Gothenburg and biotech firms Integrum AB has created a prosthetic arm as part of an ambitious European research program on prosthetic limbs DeTOP.
Surgeons attached the prosthesis to the two bones of the forearm (radius and ulna) female with titanium implants and connected 16 electrodes directly to her nerves and muscles, which allowed her to control the arm with thoughts and use it to tie your shoes and typing on the keyboard.
This is the first clinically viable, a deft and sensitive hand prosthesis, suitable for use in real life. In the published video shows how a woman uses the implant to manipulate a virtual arm on a computer screen, i.e. before you installed the prosthesis .
Conventional hand prostheses rely on electrodes which serve a limited and unreliable signals that allows you to control just a few rough movements, such as clenching your palm into a fist. Modern prosthetic hands also have a limited sensory feedback. They do not provide tactile or kinesthetic sensations, so the person when using the prosthesis could rely only on vision.
Vivsa electrodes in the nerves, researchers can electrically stimulate them, which leads to the fact that the patient perceives the sensation arising in the prosthesis.
