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.
