Red Tacton is a new Human Area Networking technology that uses the surface of the human body as a safe, high speed network transmission path.

Red Tacton uses the minute electric field emitted on the surface of the human body.

Communication is possible using any body surfaces, such as the hands,fingers, arms, feet, face, legs .

1. The RedTacton transmitter induces a weak electric field on the surface of the body.

2. The RedTacton receiver senses changes in the weak electric field on the surface of the body caused by the transmitter.

3. RedTacton relies upon the principle that the optical properties of an electro-optic crystal can vary according to the changes of a weak electric field.

4. RedTacton detects changes in the optical properties of an electro-optic crystal using a laser and converts the result to an electrical signal in a optical receiver circuit.

• 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 .

• 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.

• 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.

Touching advertising & receive information:

When a consumer stands in front of an advertising panel, advertising and information matching his or her attributes is automatically displayed.

Touch printer to touch: Print out where you want just

by touching the desired printer with one hand and a PC or digital camera with the other hand to make the link.

Just touching phone makes it your own:

Your own phone number is allocated and billing commences. Automatic importing of personal address book and call history.

Instataneous private network via personal handshake:

By shaking hands, personal profile data can be exchanged between mobile terminals on the users.

Wireless handset:Red Tacton can carry music or

video between headsets, mobile devices, mobile phones, etc. Users can listen to music from a Red Tacton player simply by putting on a headset or holding a viewer.

User verification & unlocking with just touch:

Carrying a mobile RedTacton-capable device in one's pocket, ID is verified and the door unlocked when the user holds the doorknob normally.

• 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.

• Security Devices (Development Completed)

Portable Card-Size Transmitter Embedded Receiver USB Transciever

• Data Transmission Devices (in

development)

Transciever Receiver

• We conclude that, when we compare Red Tacton with other technology present today it can give a better performance over others .

• 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.
