AMBALA COLLEGE OF ENGINEERING SEMINAR ON TOPIC RED TACTON (HUMAN AREA NETWORK) Department of Computer Science and Engineering Presented by: Prarthana 7th Semester
CONTENTS 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 TECHNOLOGY RED -> Warmth TACTON ->Action Triggered By TouchDeveloped by JAPANESE company NTTCan transmit data over the surface of body at a speed of upto-10MbpsUses 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)

EXPERIMENT ON HUMAN BODYTRANSMITTER RECIEVERFIG :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)
