Artificial hand is subject to the thoughts ( videos )
Swedish engineers have created a robotic arm that is implanted directly into the patient's bone and attached to his muscles and nerves. It allows the wearer of the prosthesis to control a prosthetic limb by thought.
In the past other researchers have already created artificial limbs, which were implemented using placed on the skin electrodes that cause muscle fibers to contract. However, so-called osteointegration system, which was developed by the specialists of the Technical University of Chalmers, promises a wider freedom of action, increased stability and more precise control thanks to the direct contact with the "biofeedback system" of man, according to the resource Re/code.
Formed by the Union of the human body and machine, biology and mechatronics, — said researcher Max Ortiz Catalan from Chalmers University in Gothenburg (Sweden).
At the beginning of last year, a new prosthesis was surgically implanted in the body of a truck driver from Sweden, who lost his arm ten years ago. Today this man confidently handle all day to day tasks: for example, automatically unpacks the food, tying the laces of their children or manage work equipment, regardless of the environmental conditions, the report said the researchers.
Currently, scientists are studying the possibility of sending signals back from the prosthetic to the brain. In other words, they're trying to give people with an amputated arm to feel again his fingers.
The video below demonstrates the capabilities of the bionic arm.
