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)

BROADBAND AND INTERACTIVE
Transmission speed does not deteriorate in congested areas
ANY MEDIACONDUCTORS
SIGNALS TRAVEL ALONG THE SURFACE OF THE MATERIAL

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)
