There's a long history of scientists and inventors who experimented on themselves. Back in 1998, Professor Kevin Warwick at the University of Cybernetics in Reading, UK, had a silicon chip implanted under his skin. It had an RFID tag attached to it and sent radio signals to different devices all over the campus. Warwick could be tracked everywhere he went, doors opened seemingly miraculously as he approached, and lights switched on in labs. The simple processes of his day-to-day life were controlled by the technology inside his body.
