3. INTRODUCTION
Developed by NTT.
Known as REDTACTON technology.
Sending the data over the surface of skin.
Human body as a data transmission path.

4. REDTACTON
“RED + TACTON = REDTACTON”
Use of H.A.N.
Communication is through touching, walking etc.
Uses human body as a transmission medium.
Uses weak electric field.
• Details of assignments and project will be announced in the class & on course web
page.
• 5 Assignments – best 4 will be considered for final grading; mix of theoretical
(paper presentation) and practical – with Demo
• Project involves three demos (1) feasibility (2) proof of concept (3) Complete
demo with weightage of 4%, 7% and 9% respectively.

5. HOW REDTACTON WORK
 By the human body contact with RED
TACTON transceiver.
 Communication occur through the surface of
body.
 Production of minute electric field by the
transmitter.
 Electric field sensor as the sensor of electric
field on the receiver.
