REDTACTON

Abstract

RedTacton is a new innovative Human Area Networking technology that turns the surface of the human body as a safe, high speed network transmission path. 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. Using RedTacton, communication starts when terminals carried by the user or embedded in devices are linked in various combinations according to the user's natural, physical movements. Communication is possible using any body surfaces, such as the hands, fingers, arms, feet, face, legs or toes. RedTacton works through shoes and clothing as well. A transmission path is formed at the moment a part of the human body comes in contact with a RedTacton transceiver, physically separating ends the contact and thus ends communication. 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 affect 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. NTT developed super sensitive Photonic electric field sensor for detecting minute electric field emitted on the surface of the human body.
