HUMAN AREA NETWORK What is RED TACTON ? Principle Involved Block diagram of Red Tacton transceiver Experiments on Human body Features of Red Tacton Obstacles

DON’T YOU HAVE A LAN CONNECTION

USE YOUR BODY!!!!!!

HUMAN AREA NETWORK

• Interconnection of information technology devices within the range of an individual person.

• HAN technology creates an external electric field that passes an incredibly tiny current through the body.

• The current used is one-billionth of an amp

WHAT RED TACTON

AN INNOVATIVE NETWORK TECHNOLOGYRED -> Warmth

TACTON ->Action Triggered By Touch

Developed by JAPANESE company NTT Can transmit data over the surface of body at a speed of upto-10Mbps Uses weak electric field on the surface of body to transmit data.

PRINCIPLE OF RED TACTON

Ea: ELECTRIC FIELD induced towards the body

Eb: ELECTRIC FIELD

Induced from body

Ec: ELECTRIC FIELD

escaping from body to ground

Es: ELECTRIC FIELD that reaches receiver i.e. ES=EA-(EB+EC)

FIG :EXPERIMENTAL SET UP TO SHOW INTRABODY COMMUNICATION

HUMAN SAFETY• Transceiver ends are completely insulated• Displacement current generated by electrons are present everywhere in

human body. • Body is subjected to minute electric fields so such displacement currents

are common everyday occurrences.• The current used 1 Nano amp which is lower than the natural currents

already in the body

OBSTACLES• Needs a lot of research and development.• Many popular technologies exist in the marketplace e.g.: Bluetooth• Cost and time to develop Personal Area network technology is very

expensive• This technology will not likely be very useful until a large number of

people and devices have adopted it which means a significant time investment

• Touching a body in PAN could be as good or as bad as tapping into a telephone line (therefore a security method using encryption should be adopted that makes the PAN data look like a stream of random bits to would-be eavesdroppers)
