Researchers in Europe are working to create a prosthetic hand with a sense of touch.
The prototype lets an amputee feel differences in the shape and hardness of different objects, and adjust grasp in response.
Dennis Sorensen of Denmark lost his hand in a fireworks accident more than a decade ago.
He was allowed to experiment with the prosthetic hand for a week.

The artificial hand picks up electrical signals from artificial tendons controlling the movement of its fingers, which are sent down fine wires to four electrodes implanted in sensory nerves in the upper arm.
It’ll take years of additional research before prosthetics that feel become a widespread reality, but the research shows it’s possible.
