Today, the University of Utah announced a $10 million contract, as part of the overall project, to develop a "peripheral nerve interface." The implanted device would relay nerve impulses wirelessly from what?s left of a limb to a computer worn on the person?s belt. From there, the signals would be routed to a bionic arm and back to the remainder of the amputated arm, where they would then flow naturally back to the brain.
Researchers at the university have already developed a pill-sized array with 100 tiny electrodes. Now they?ll seek to improve on the arrays so they can be implanted in up to four of the major nerves in a patient?s residual arm. Each electrode would communicate with a small number of fibers within a nerve.
"Imagine an artificial arm that moves naturally in response to your thoughts, that allows you to feel both the outside world and your own movements, and that is as strong and graceful as an intact, biological limb," said bioengineer Greg Clark, the University of Utah's principal investigator on the project. "That's what our researchers, teaming with others around the world, are setting out to achieve.?
Over the next four years, other scientists will build a next-generation mechanical arm designed to work like the real thing.
