Researchers have developed a prosthetic skin that may, if it works, allow amputees to regain a sense of touch in the missing limb. (And because it's a skin, it may also make the prosthetic limb look more realistic. Unless, of course, the person wants a bright purple one or one that looks like Bucky's). It's still in the early stages of animal testing and we won't know until somebody makes one and puts it on a volunteer - but I suspect they won't have a shortage of people willing to try it.
