Scientists have created a bionic arm that could "feel"

The work, carried out by researchers at the Swiss Federal Institute of Technology in Lausanne, Switzerland,  developed a bionic prosthesis human hand, which allows its owner to feel varying degrees of pressure, which are called tactile sensations, reports MIT Technology Review .

Novelty, which became a sensation in Biomechatronics, has been successfully tested Dutchman who after an accident with fireworks left without a left hand.

After implantation of the prosthesis to this man took over a month to once again feel the touch, as it was before the accident. Swiss scientists created a prosthesis not only receives signals from the brain, but also gives him the feeling that occur at different degrees of pressure.

Opportunity to relive tactile sensations appeared after the nerve endings during surgery were connected to the electrodes. Once touch sensor bionic prostheses strength to various substrates, the electrical signals received by electrodes implanted. Those are in turn influenced by the central nervous system of man.
Recall that in the United States was developed bionic prosthetic leg, which the patient experienced a rather extreme way - man walking climbed the stairs to the 103rd floor of a skyscraper.



Details of the Swiss implant are published in the journal Science Translational Medicine.
