In recent years, researchers devote much time to the improvement of the prosthetics of people with disabilities. Scientists have created a prosthetic that gives man some tactile sensations. However, a group of researchers managed to create a prosthesis, which not only made it clear the person holding the object or not, and also provided a sense of what the user holds in his hand.
Scientists in 2012 were implanted subject is Igor, Spetic the electrodes in the nerve bundles of his hand. In total, there were added 19 different points for stimulation. For a start, researchers have developed special algorithms that stimulated the electrodes sending signals to the brain of man, so that he could not only distinguish between the shape of the object but also its texture.
After that, the scientists disconnected the external stimulation, and the electronic signals are sent to the prosthesis. The subject noted that he was using the prosthesis could feel the same sensations as in the process of stimulating, according to the resource Gizmag.
In addition to the functions of sensation, the prosthesis has one positive side effect. According to Igor, Specic, during the experiment he almost lost the phantom pain of an amputated hand.
The creators report that they are going in the next five years to adapt this technology to be able to use it at home. In addition, in the future they plan to create sensitive prosthetic legs to allow the user to determine on what surface he's moving.
