Every day your fingers, wrists and forearms conduct the symphony of motor movements that allow you to click a mouse, type on a keyboard or swipe a screen. But what if you lost your hand? What kind of machine could restore your abilities to grip, click, tap or touch? > In a new study, a group of researchers at the University of Utah have re-engineered a prosthetic system to let a man whose hand was amputated feel a wide range of sensations, helping him physically grasp a variety of delicate objects, from a glass of wine to a single grape. Although other prosthetics have enabled wearers to receive sensory feedback, the modified system ramps up the subtle detection of sensation in the hand.
