Created a prosthesis with artificial skin that conveys sensations

Researchers from Johns Hopkins University have created an artificial skin (e-dermis) that, when applied to a prosthesis, allows you to feel the shape of objects, their temperature and relieves phantom pain in a lost limb.

Artificial dermis is created from a combination of special fabric, rubber and a layer of sensors that mimic the receptors of human skin. They can transmit tactile sensations, for example that an object is sharp, and then send them through wires to peripheral nerve tissues in the rest of the limb..

The transmitted signals must be configured individually for each. To do this, researchers use subcutaneous electrical nerve stimulation and study brain activity to determine what signals need to be generated to convey specific sensations. They actually train artificial skin to encrypt a variety of signals, similar to human skin..

Although the invention does not yet fully convey all feelings, volunteer Luke Osborne says that thanks to the invention he felt that his hand «full of life». In the future, e-dermis can help even robots feel the world in the same way as humans..
