This seminar discusses Red Tacton technology, a new human area networking technique developed by NTT that can transmit data through weak electric fields on the surface of the human body at speeds up to 10 Mbps. It relies on changes in the optical properties of electro-optic crystals caused by electric fields. Prototypes include PC card and hub transceivers. Red Tacton has advantages like wireless data transfer with just a touch and strong security since the human body is the transmission medium. However, its design is complex and expensive compared to other technologies.
