Will the human body become the next data conduit? NTT, a Japanese communications firm, has developed a technology called RedTacton that makes that seem not so far fetched.

RedTacton, [...] (NTT) claims can send data over the surface of the skin at speeds of up to 2Mbps — equivalent to a fast broadband data connection.

…

RedTacton doesn’t introduce an electric current into the body — instead, it makes use of the minute electric field that occurs naturally on the surface of every human body. A transmitter attached to a device, such as an MP3 player, uses this field to send data by modulating the field minutely in the same way that a radio carrier wave is modulated to carry information.
