For the past 7 years, researchers in Sweden have been studying a new type of mind-controlled prosthetic arm that could drastically improve the lives of people who’ve lost a limb.
The arm prosthesis is implanted through a process called osseointegration, in which the prosthesis is surgically attached to the bone, muscles, and nerves.
The technology involves implanting electrodes that pick up on the brain’s signals and allows people to move, feel, and use the new limb in an intuitive, natural way.
“I usually say that with a traditional sleeve prosthesis, you wear the prosthesis — it is a medical device. But with osseointegration, the medical device becomes a part of you. You don’t feel that you are wearing the prosthesis; rather, it’s a part of you,”
The key difference is that the electrical sensors used with myoelectric prostheses are attached to skin from the outside socket, whereas the new mind-controlled osseointegrated prosthesis has all the wiring under the skin
