Swedish scientists have connected the prosthetic hand directly to the nerves of the women, allowing her to move your fingers with your mind and even to feel tactile sensations.
This is a huge step forward compared to existing dentures, which often rely on electrodes located on the outside of the skin, informs Rus.Media.
Researchers from the Technological University of Chalmers (Gothenburg, Sweden) and biotech firm Integrum AB has created protezno hand an ambitious European research program on prosthetic limbs DeTOP.
Surgeons attached the prosthesis to the two bones of the forearm (radius and ulna) female with titanium implants and connected 16 electrodes directly to her nerves and muscles, which allowed her to control the arm with thoughts and use it to tie your shoes and typing on the keyboard. This is the first clinically viable, a deft and sensitive hand prosthesis, suitable for use in real life. This achievement was reported on the official website of the project.
“The breakthrough of our technology is to give patients the opportunity to use implanted neuromuscular interfaces for the management of their prosthesis, while experiencing feelings that are important in everyday life”, – says an employee of the University of Chalmers Ortiz Catalan (Ortiz Catalan).
Electronics connected to the human nervous system, allows you to create new ways of interacting with technology. In the video, which was released by Swedish scientists, shows how a woman uses the implant to manipulate a virtual arm on a computer screen, i.e. before you installed the prosthesis.
Conventional hand prostheses rely on electrodes located over the skin, for controlling signals from lower limb muscles of a person. These surface electrodes present limited and unreliable signals that allow you to control just a few rough movements, such as palm grip into a fist.
Modern prosthetic hands also have limited sensory feedback. They do not provide tactile or cinestation feelings, so people when using the prosthesis could rely only on vision: for example, their owners can’t tell you how much they compress the object. Vivsa electrodes into the nerves that had previously been associated with lost biological “sensors” hands, researchers can electrically stimulate these nerves, which leads to the fact that the patient perceives the sensation arising in the prosthesis.
New invention became a kind of harbinger of a future in which robotic devices easily interact with our bodies. For decades, these prostheses seemed possible only in the universe of “Star wars” and other works of science fiction, but this development shows that such a future has already arrived, despite the fact that the technology has not yet appeared in public.
