Nippon Telegraph and Telephone Corporation: RedTacton
REDTACTON::
• Technology is making many things easier.
• Nippon Telegraph and Telephone Corporation(NTT, headquartered in Chiyoda-ku, Tokyo. President and CEO, Norio Wada) is pursuing research and development of an innovative Human Area Networking technology called “RedTacton”.
• REDTACTON safely turns the surface of the human body into a data transmission path at speeds up to 10 Mbps between any two points on the body.
• REDTACTON uses the minute electric field emitted on the surface of the human body.
• REDTACTON enables the first practical Human Area Network between body-centered electronic devices and PCs or other network devices embedded in the environment .
• REDTACTON can be used for intuitive operation of computer-based systems in daily life, temporary one-to-one private networks based on personal handshaking, device personalization, security are enabled by the redtaction.
WORKING PRINCIPLE
• “RedTacton” takes a different technical approach. Instead of relying on electromagnetic waves or light waves to carry data.
• RedTacton uses weak electric fields on the surface of the body as a transmission medium.
• “RedTacton relies upon the principle that the optical properties of an electro-optic crystal vary according to the changes of a weak electric field”.
• A RedTacton transmitter couples with extremely weak electric fields on the surface of the body.
• The weak electric fields pass through the body to a RedTacton receiver, where the weak electric fields affects the optical properties of an electro-optic crystal.
• The extent to which the optical properties are changed is detected by laser light which is then converted to an electrical signal by a detector circuit.
