In addition to becoming bionic, prostheses may soon help a person feel bionic too. Bionic hands with gelled fingertips may be the answer to giving the wearer a sense of touch and sensitivity. It may even help them instinctively hold objects. That’s because humans have a reflexes that respond to vibrations. The top part of the bionic hand would consist of a rubber skin filled with silicon gel.

When an object slips, the skin transmits the vibrations through the gel to acoustic sensors, giving the wearer feedback so that the motors can tighten their grip. Also, the finger is also covered with electrodes, which change the electric conduction to accompany the pressure. So now they will be able to feel as well as function.
