Abstract
RedTacton is a human area network technology that uses the surface of the human body as a safe high-speed network transmission path. The technology is called TACTON because this influences communication that starts by touching leading to various actions. RED is used to convey the meaning of warmth in communication. Instead of relying on electromagnetic waves or light waves to carry data, 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. Physically separating ends the contact and thus closes the communication. The RedTacton chips will be embedded in machines and contain a transmitter and receiver built to send and accept any form of data stored in digital format.
WORKING PRINCIPLE:
1. How Red Tacton works?
Using a new super-sensitive photonic electric field sensor, RedTacton can achieve duplex communication over the human body at a maximum speed of 10 Mbps.
1. The RedTacton transmitter induces a weak electric field on the surface of the body.
2. The RedTacton receiver senses changes in the weak electric field on the surface of the body caused by the transmitter.
3. RedTacton relies upon the principle that the optical properties of electro-optical crystal can vary according to changes of a weak electric field.
4.Redtacton detects changes in the optical properties of an electro-optic crystal using a laser and converts the result to an electric signal in an optical receiver circuit.
It is to be noted that Redaction transceivers which integrate transmitter and receivers, are also available. The physical layer enables half-duplex communication(transmission and reception are done alternatively)using proprietary CSMA/CD protocol. As with Ethernet cards, each transceiver card has a unique address. The upper layer above this is compliant with TCP/IP protocol.
2.Method of communication with RedTacton
The transmitter sends data by inducing fluctuations in the minute electric field on the surface of the human body. The surface of the human body loses some field due to the returning to ground and electric field dissipated to the earth from legs. Data is received using a photonic electric field sensor that combines an electro-optic crystal and a laser light to detect fluctuations in the minute electric field. This sensor measures faint electric field by using a laser beam to detect fluctuations in the optical properties of electro-optic crystal that are caused by peripheral electric fields.
The illustration is as shown in the figure. It clearly depicts various paths of the field.
the crackling sensation one feels when shocked by static electricity is caused by an electric current of several dozen milli-amperes suddenly flowing into the body from the outside. The RedTacton electrode is covered with an insulating material, no current flows into the body from the RedTacton transceiver. As a result, there is no shock caused by the inflow of electric current from the outside. However, as in mobile phones, a weak induction current is created in the body owing to the minute electric filed created near the body when the movement occurs. This induction current is very weak and similar to those occurring in everyday life. The size of the induction current emitted on the body with RedTacton is in conformity with the "Radio Frequency-Exposure Protection Standard <RCR STD-38> established by the Association of Radio Industries and Businesses (ARIB).

RedTacton uses the human body as a path for the electric signals that are communicated to represent data. The transmitter worn on a body uses the body’s electrical field to transmit digital messages. For example, by shaking hands two people can exchange business cards. When a user touches a door handle, the system realizes who the person is and gives the authorization. By holding a camera in one hand and touching the printer with the other the photographs can be printed. By touching a mobile phone, the address book can be downloaded. However, a distinction between an electric sensor and a photonic electric field sensor is also illustrated. Photonic electric field sensors used in RedTacton can measure stand-alone contacts without being influenced by grounds. As a result, the received waveform is not distorted, regardless of the receiver location. This makes long-distance and high-speed body surface transmission possible.
