In 1998, a transponder or silicon chip was surgically implanted into the forearm of a British scientist. It sent identifying signals to a central computer that tracked his movements and allowed him access to his workplace, by opening doors and switching on lights. Professor Kevin Warwick has been speaking to Farhana Haider about becoming a more enhanced version of himself and as a result the world's first Cyborg: a man-machine hybrid.
