Technology that restores the sense of touch in nerves damaged as a result of injury

Researchers have developed a sensor that can be implanted anywhere in the body -- for example, under the tip of a severed finger. The sensor connects to another nerve that functions properly and restores tactile sensation to the injured nerve. The development is biocompatible and does not require electricity, wires, or batteries.
