- An Artificial Hand with Real Feelings
A new nerve interface can simulate a sense of touch from 20 spots on a prosthetic hand.
There have been remarkable mechanical advances in prosthetic limbs in recent years, including rewiring nerve fibers to control sophisticated mechanical arms (see “A Lifelike Prosthetic Arm”), and brain interfaces that allow for complicated thought control (see “Brain Helps Quadriplegics Move Robotic Arms with Their Thoughts”). But for all this progress, prosthetic limbs cannot send back sensory information to the wearer, making it harder for them to do tasks like pick up objects without crushing them or losing their grip.
