Kevin describes his implants

This is implants, 1998. The doctor putting it in my left arm, implant on the right hand side. This was like an identification device. It was implanted in my upper left arm, and ah, essentially the computer opened doors for me, switched on lights. For some reason, I received criticism when this happened.

This is from my 2002 implant. This was carried out at the Radcliff Infirmary in Oxford. The operation took two hours, and there were a whole group of neurosurgeons involved because no human had had this implant before, so they actually practised on lumps of meat from the supermarket in North Oxford before they tried it out on me so I was quite confident they knew what they were doing. Most of the time it worked in the lump of meat. This is what the implant actually looked like. You can see there. There are 100 very, very small electrodes. The 100 electrodes are about one and a half millimeters long so they’re very, very small. This was fired into my medium nerve. There are about 10,000 nerve fibres running down your arms, or in my case my arms, and they’re about 4 mm in diameter, this whole bunch of nerve fibres, so these electrodes were fired in almost half way into the nerve fibres, ah making electrical contact.
