Red Tacton is a new human area network technology developed by Japanese company NTT that uses weak electric fields on the surface of the human body for high-speed network transmission. It works by creating changes in electric fields from a transmitting transceiver that are received by a sensing receiving transceiver. Data transfer is faster and more secure compared to other technologies, though it has a limited range of a few centimeters and is more costly. Potential applications include touch-based controls and transferring various media types through the human body.

5. Principle

6. How it works
Red Tacton relies upon the principle that the optical
properties of an electro-optic crystal can vary
according to the changes of a weak electric field.

transceiver

8. Working Procedure
• Transmitting transceiver creates a change in the
field
• Some field from human body dissipates into
earth
• Electric field is received using sensing
technology
• Receiving transceiver recognizes the change in
the electric field
• sensing technology measures the weak electric
fields induced.
• Electro-optical crystal uses laser to convert and
read the signal

9. Security
 The transmitting and receiving electrodes
of the RedTacton transceiver are completely
covered with insulating film
 When communication occurs , displacement
current is generated by the electrons in the
body because the body is subjected to
minute electrical fields. However, such
displacement currents are very common
everyday occurrences to which we are all
subjected.
 You decide what to share with whom and
what devices you communicate with

10. Features
• Touch
• Broadband & Interactive
• Any Media

11. Touch
Touching, gripping, sitting, walking,
stepping and other human movements can
be the triggers for unlocking or locking,
starting or stopping equipment, or
obtaining data

12. Broadband & Interactive
• Duplex, interactive communication is possible
at a maximum speed of 10Mbps. Because
the transmission path is on the surface of the
body, transmission speed does not
deteriorate in congested areas where many
people are communicating at the same time.
• Maximum communication speed may be
slower than 10Mbps depending on the usage
environment.

13. Media
In addition to the human body, various
conductors and dielectrics can be used as
transmission media. Conductors and
dielectrics may also be used in
combination

14. Advantages
• Data transfer is faster and easier through this technology
• Data loss during transfer is less
• Use of minimum amount of power(of some milli volt
range)
• Security is more
Drawbacks
• It has no compelling applications that aren’t already
available
• Too costly
• It can be useful within few centimeters only

15. Applications

16. Conclusion
• We conclude that, when we compare
Red Tacton with other technology
present today it can give a better
performance over others
• And we can say that to connect the
network with in short distances Red
Tacton is best.
• In this technology there is no problem of
hackers as our body is itself a media.
