human body as a media

Communications path by simple touch

RedTacton is a Human Area Networking technology developed by NTT Docomo, that uses the surface of the human body as a network transmission path. Communication starts when the skin comes in contact with a transceiver and ends with physically separation.
The system works through shoes and clothing as well.

Human skin data transmission technology
Matsushita Electric Works has developed the human skin data transmission technology and started selling it to manufacturers of mesuring apparatuses including Teraoka Seikou.
Teraoka Seikou will be able to build a system for sales agents who sell, for example, meat by weight. They will wear a wrist-band that accumulates information. When a customer orders, say, ground beef, a sales agent touches a corresponding digitally-enhanced product information card. This data is transmitted through the sales agent's skin and stored in his wristband. When he puts some ground beef on an electronic scale and touches it the data in thewrist band are transmited to the scale.

The technology can be used both for "human-human communication " and "human-machine" communication.
