About two million people in the U.S. have lost an arm, a hand, a leg or other limb. Many opt to use a prosthesis -- a fabricated upper or lower limb. Luke Osborn, a graduate student in biomedical engineering at Johns Hopkins University, tells us about an electronic skin that can create the sensation of touch for the user of an upper-limb prosthesis. And George Levay, a research participant who lost his arms to meningitis, describes what it was like using the electronic skin on his prosthetic hand.
