2. 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

3. DON’T YOU HAVE A LAN
CONNECTION
USE YOUR BODY!!!!!!

4. 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

5. WHAT RED TACTON
AN INNOVATIVE NETWORK TECHNOLOGY
RED -> 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.

6. 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)

8. BLOCK DIAGRAM OF RED TACTON
TRANCIEVER

9. FEATURES

10. TOUCH

11. BROADBAND AND INTERACTIVE
Transmission speed does not deteriorate in congested areas

12. ANY MEDIA
CONDUCTORS
SIGNALS TRAVEL ALONG THE SURFACE OF THE MATERIAL

13. CONTINUED..
ANY MEDIA
DIELECTRIC
SIGNALS PASS THROUGH THE MATERIAL

14. Continued…
ANY MEDIA
CONDUCTOR+DIELECTRIC
COMBINATION OF TRAVELLING ALONG AND PASSING THROUGH THE MEDIA

15. EXPERIMENT ON HUMAN BODY
TRANSMITTER
RECIEVER
FIG :EXPERIMENTAL SET UP TO SHOW INTRABODY COMMUNICATION

16. 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

17. 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)
