Forget about optical fibres. IBM has come up with a brand new data transmission medium - the human body.
At Comdex last week, researchers from IBM's Almaden research labs demonstrated tiny computers that can send and receive data through the human body at speeds of around 2400 bps. IBM demonstrated the technology by using it to read data from an electronic card when one person shook hands with another. The second individual was holding a receiver that picked up the text data transmitted by the card.
Those worried about the possibility of electric shocks from the system need not be alarmed. According to IBM, the current used is one thousandth of that created when a balloon is rubbed against a sweater to make it stick on a wall. Someone had better tell the kid in this picture.
