RED TACTON

RED TACTON

RedTacton is a new Human Area

Networking technology that uses the

surface of the human body as a safe,

high speed network transmission

path.

It uses the minute electric field emitted

on the surface of the human body.

A transmission path is formed at

the moment a part of the human

body comes in contact with a

RedTacton transceiver.

Communication is possible

using any body surfaces, such

as the hands, fingers, arms,

feet, face, legs or torso.

The transmitter sends data by inducing fluctuations in the minute electric field on the surface of the human body. 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.

COMPARISON WITH OTHER HUMAN COMMUNICATION METHODS

Touching, gripping, sitting, walking, stepping etc can be the triggers for unlocking or locking, starting or stopping equipment, or obtaining data.

In addition to the human body, various conductors and dielectrics can be used as transmission media.

Duplex, interactive communication is possible at a maximum speed of 10Mbps.

APPLICATIONS AT A GLANCE

The transmitting and receiving electrodes

of the RedTacton transceiver are completely

covered with insulating film, so the body of the

person acting as the transmission medium is

completely insulated. This makes it impossible

for current to flow into a person’s body from

the transceiver.

RedTacton conforms to the “Radio

Frequency-Exposure Protection Standard (RCR

STD-38)” [6] issued by the Association of

Radio Industries and Businesses (ARIB). The

levels produced by RedTacton are well below

CONCLUSION

RedTacton is an exciting new technology for human area networking.

While our immediate objective is to implement a RedTacton system supporting two-way intrabody communication at a rate of 10 M bit/s between any two points on the body.

Our longer-term plans include developing a mass-market transceiver interface supporting PDAs and notebook computers while continuing efforts to reduce the size and power consumption of the transceiver to enhance its portability.
