Luke Skywalker's Prosthetic Arm Inspired This Electronic Skin

Remember the robotic prosthetic arm the Rebel fleet replaced Luke Skywalker's hand with after Darth Vader severed it in an epic lightsaber duel in The Empire Strikes Back? Of course you do--and so do scientists. Luke's cybernetic replacement limb was pretty badass, but not exactly replicable in the medical world at the time, or even now. But a team of researchers at the National University of Singapore are hoping to change that with a new kind of artificial nervous system. Think of it as electronic "skin."
