Up here you have a simple explanation in English of the invention. Patients can move their arm , thanks to redirected nerves that send electrical signals to sensors placed on their chest . In addition, they can perceive certain sensations in this area, but it is intended to go much further. Advances indicate that in the future the arm could be controlled with thought , and even transmit complex sensations (pressure or temperature, for example).
The first prototype was implanted in the American Jesse Sullivan four years ago (2002). Jesse is an electrician and suffered a tremendous accident in May 2001 when he touched a wire with a voltage close to 7,500 volts . According to local6.com, our friend has a gossip that costs six million dollars .
The second person to receive one of these prostheses was the young Claudia Mitchell (27 years old). The ex-marine lost her left arm in a motorcycle accident and has been working with her robotic limb since August 2006 . Now Claudia can put on her shoes, wash or peel a banana.
The arms were designed and implanted at the Chicago Rehabilitation Institute under the supervision of Dr. Todd Kuiken and are part of a project funded by DARPA.
The reality again than fiction. A few years ago, a bionic arm was something that we could only imagine in the Terminator (now turned Governator ) movies or in Star Wars.

Returning to the real world, now two people with amputated limbs have improved their quality of life after their accidents thanks to these artificial arms .
