Red Tacton is a technology that allows for communication between devices through human contact using electric fields on the surface of the skin. It works on the principle that changes in a weak electric field induced on the human body can be sensed. A Red Tacton device consists of a transmitter that induces an electric field and a receiver that senses changes in the field. This allows for duplex communication at speeds up to 10 Mbps through touching any part of the body. Potential applications include controlling devices with touch and creating secure personal area networks through handshakes.

4.  RED TACTON meaning:
tacton: touch-act-on (action triggered by touching)
red: symbol of warmth and love conveying the cordiality of
interpersonal communications
 Red Tacton works on HAN. (Human area networking), as a safe,
high speed network transmission path.
 RedTacton uses weak electric fields on the surface of the body as a
transmission medium.
 Technically its completely distinct to wireless and infrared.
 Communication possible through any part of the body.
 Red Tacton can achieve duplex communication over the human
body at a maximum speed of 10 mbps.

5.  Major components of device are a red Tacton transmitter and a
receiver.
 Transmitter induces a weak electric field on the surface of the body.
 Receiver senses changes in the weak electric field on the surface of
the body caused by the transmitter.
 Red Tacton works upon the principle that the optical properties of
an electro-optic crystal can vary according to the changes of a weak
electric field.
 using a laser and converts the result to an electrical signal in a
optical receiver circuit.

8.  There are 2 basic methods:
1. Electric current method
2. Electric field method( Red Tacton)

9. A communications path can be created
with a simple touch.
 Two-way communication is supported
with speed 10 Mbps & Frequency less
than resonant frequency of human(70-
100 Mhz)
RedTacton can utilize a wide range of
materials as a transmission medium.

10.  The naturally occurring electric field induced on the surface of the
human body dissipates into the earth.
 Photonic electric field sensors are developed which bounces a
laser beam off of a crystal (electro-optic crystal) and measures the
reflected beam.
 Opto-electro sensors has two features :
1. Should measure electric field from a device without contacting it.
2. Ultrawide band measurement possible & Should support one
point measurement independent of ground.

11. MECHANISM OF COMMUNICATION WITH
REDTACTON

12.  In addition to the WANs (Internet) and LANs, there are applications best
served by Human Area Networks (HANs) as well.

14.  Many human movements like touching, gripping, walking, stepping
etc. can lock or unlock equipments or start or stop an equipment or can
result in data transfer
 Communication starts when any body part or embedded system gets in
contact through various physical contacts according to human natural
movements .

15.  Bandwidth is not at all affected with the variations in the number of
users and also not affected with the use of duplex operation.
 Because the transmission path is surface of the body, the speed is not
compensated in congested areas.

16.  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.

17.  Safety is obviously the primary concern before the implementation of
this technique.
 The transmitting and receiving electrodes of the Red Tacton transceiver
are completely covered with insulating film.
 So the body of the person acting as the transmission medium is
completely insulated.
 When communication occurs, displacement current is generated by the
electrons in the body because the body is subjected to minute electrical
fields.

22. 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.
DISADVANTAGES
 It can be useful within few centimeters.
 Effects on human body is still under research.
 Cost of development.

 a cabinet that opens only to authorized people
 a television control that automatically chooses favorite programs.
The system also improves security.
 It can dominate Bluetooth technology in future
 It ensures that only drivers can open their cars by touching the doors if
the keys are in their pockets, not people around them.

25.  Red Tacton is an exciting new technology for Human Area
Networking.
 It is best to connect network within short distances with speed of
10Mbps.
 There is no any type of problem of hackers as our body itself is the
transmission media.
 It can dominate Bluetooth technology in the future and can end the use
of cables.
 It supports personal devices like PDA’s and notebooks.
 Since it provides high speed communication, it can provide seamless
service wherever, whenever and whoever uses it.
