The bionic fingers look just like the real thing and they work extremely well. The bionic fingers can be controlled by measuring electric signals from nerves using pads on the skin. Touch Bionics has fitted more than thirty patients with the devices, each uniquely built to correspond to differing levels of amputation. The bionic fingers can detect objects as they close to prevent crushing something delicate and can be installed in different grips to help with tasks such as typing.
