An Artificial Hand with Sense of Touch

There have been excellent advances in prosthetic limbs in some previous years. But with all such advancements it is still not possible for prosthetic limbs to send information back to the wearer and its making it harder for them to do a pick up object task without crushing them and losing their grip.

Now researchers have developed  a new interface that can convey a sense of touch from 20 spots on prosthetic hand by directly stimulating nerve bundles also known as peripheral nerves in the arms of patients. So this interface can let user feel what they are picking up.

There is a video shown below of a 48 year old man who lost his right hand in a accident but now using a prosthetic hand to pick up and remove stems from cherries without crushing and squeezing them.
