We've seen some very cool prosthetic arms recently, including ones people are able to control—just as they control biological arms—with their thoughts. So what's one of the next great frontiers for prosthetics? Letting people experience touches through them, too.
The human sense of touch does a lot more than let people enjoy fresh sheets or soft kitties. It's also crucial for helping people judge how hard to hold stuff they want to pick up, or whether they've got a good grip on something slippery. In a feature published earlier this year, Nature News talked with one prosthetic arm user, Igor Spetic, who accidentally broke dishes and bruised fruit he tried to hold with his device.
