The Ossur system uses implanted sensors sending wireless signals to the artificial limb’s built-in computer
Biomedical engineering company Össur has announced the successful development of a thought controlled bionic prosthetic leg. The new technology uses implanted sensors sending wireless signals to the artificial limb’s built-in computer, enabling subconscious, real-time control and faster, more natural responses and movements.
Prosthetics controlled by muscle impulses have been around since the late 1960s, but the technology has severe limitations. It works by laying sensors on the skin of the vestigial limb, which picks up electrical impulses that control, for example, an artificial arm. The trouble is, these sensors pick up electric impulses from more than one muscle. This degrades performance, requires a lot of practice to operate properly, and makes the prosthesis slow, Imprecise, and frustrating to use. .
