Defense Advanced Research Projects Agency have been working to field a brain-controlled prosthetic arm that the wearer can operate by thought.

 But DARPA’s current version of the prosthesis — not ready for prime time — requires a hard-wired interface, a brain sensor and clunky plug inserted into the head and connected by wires to an external computer that controls the arms.

A breakthrough announced Tuesday by the National Institutes of Health may propel the DARPA Revolutionizing Prosthetics program closer to its ultimate goal: a bionic arm that works like a real one, controlled by thoughts and as nimble as Luke Skywalker’s in “The Empire Strikes Back.”
