Prosthetic
The prosthetic electric hand was created in 1971 by Helmut Lucas. The electric prosthetic detect signals from the users nervous or muscles systems, this then leads to a controller located inside the devise that processes feedback such as position and force ("Robotic prostheses."). With many people living with no hand from trauma or disease, Helmut Lucas was able to help them to live their life as normally as possible again. Nowadays, prosthesis are not only used for livability but also movies.
