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. Taking advantage of this speed, device drivers can be downloaded instantly and Fig 7. Marketing execute programs can be sent.

Too costly. It can be useful within centimetres. Effects on human body is still under research. It is highly secure and impossible to get hacked. It is a high speed network and well suited for short distance communication. In future , where man is destined to reach new heights of technology ,a trend like RedTacton is likely to direct him in the right direction giving him hope and motivation than any other technology man is able to perceives on the human centered interaction.
It uses the minute electric fields emitted on the surface of the human body. Technically, It is completely distinct from wireless and infrared. A transmission path is formed at the moment a part of the human body comes in contact with a RedTacton transceiver. Physically separating ends the contact and thus ends communication medium. The weak electric fields pass through the body to a RedTacton receiver, where the weak electric fields affect the optical properties of an electro-optic crystal.
Fig 1. Using RedTacton, communication starts when terminals carried by the user or embedded in devices are linked in various combinations according to the user's natural, physical movements. RedTacton works through shoes and clothing as well. Chapter 2 HISTORY At the end of the Japanese telecommunications group NTT had announced that it would develop a new data transmission technology that uses the conductive properties of the human body to exchange information between electronic devices.
NTT reckons this latest advance on the wireless Personal Area Network concept - dubbed RedTacton- can transmit data over the surface of the skin at up to 2Mbps. Where it differs, though, from previous offerings, is that a RedTacton-enabled device does not have to be in direct contact with the skin - only within about 20cm.
RedTacton can achieve duplex communication over the human body at a maximum speed of 10Mbps. The RedTacton transmitter induces a weak electric field on the surface of the body. The electric field sensor transistor or photonic electric field sensor detects electric field that reaches the RedTacton receiver.
Signals are processed in the receiver circuit and the data is downloaded. Fig 3. The transmitter sends data based on fluctuations in the weak electric field induced in the body. The electric field is received using super-sensitive electric field sensing technology. The naturally occurring electric field induced on the surface of the human body dissipates into the earth. Therefore, this electric field is exceptionally faint and unstable.
The supersensitive electric Field sensing technology measures the weak electric fields induced by the superefficient alternating electric field induction technology developed by NTT. Instead of relying on electromagnetic waves or light waves to carry data. Using a new super-sensitive photonic electric field sensor, RedTacton can achieve duplex communication over the human body at a maximum speed of 10 mbps.
The RedTacton receiver senses changes in the weak electric field on the surface of the body caused by the transmitter. 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. Red Tacton detects changes in the optical properties of an electro-optic crystal using a laser and converts the result to an electrical signal in an optical receiver circuit.
The transmitter sends data by inducing fluctuations in the minute electric field on the surface of the human body. Data is received using a photonic electric field sensor that combines an electro-optic crystal and a laser light to detect fluctuations in the minute electric field.
Page 10 Human Area Networks — RedTacton Report A Seminar electric fields to be measured by detecting changes in the optical properties of an electro-optic crystal with a laser beam. We implemented a receive-first half-duplex enable two-way communication scheme that sends only after checking to make sure that there is no data to receive in order to avoid packet collisions between terminals in compliance with the IEEE Page 11 Human Area Networks — RedTacton Report A Seminar detector circuit that amplifies the minute incoming signal from the electro optic sensor and converts it to electrical signal.
Fig 4. A communications path can be created with a simple touch, automatically initiating the flow of data between a bodycentric electronic device and a computer that is embedded in the environment. 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.
RedTacton can utilize a wide range of materials as a transmission medium, as long as the material is conductive and dielectric, which includes water and other liquids. A communication environment can be created easily and at low-cost by using items close at hand, such as desks, walls, and metal objects. But there is one limitation on the length of the conductor to be propagated, on installation locations, and on the thickness of the dielectric to be passed through.
One-to-One Services With the ability to send attribute data from personal information devices worn on the body to computers embedded in the environment, one-to-one services could be implemented that are tailored to the individual needs of the user. Intuitive operation of personal information Communication is triggered by totally natural human actions and behavior, so there is no need to insert smart cards, connect cables, tune frequencies, or any of the other inconveniences usually associated with today's electronic devices.
Device personalization Setup, registration, and configuration information for an individual user can all be uploaded to a device the instant the device is touched, eliminating the need for the device to be registered or configured in advance. New behavior patterns Tables, walls, floors and chairs can all act as conductors and dielectrics, turning furniture and other architectural elements into a new class of transmission medium.
For example, a user could have instant access to the Internet merely by placing a laptop onto a conductive tabletop. Marketing applications When a consumer stands in front of an advertising panel, advertising and information matching his or her attributes is automatically displayed. Page 15 Human Area Networks — RedTacton Report A Seminar or standing in front of items they are interested in, consumers can get more indepth information.
Security applications Red Tacton could be installed on doors, cabinets and other locations calling for secure access, such that each secure access could be initiated and authenticated with a simple touch. At the same time, all the transaction details and relevant user attributes personal identity, security clearance, etc.
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. If the user touches the wrong medicine, an alarm will trigger on the terminal he is carrying. The alarm sounds only if the user actually touches the medicine bottle, reducing false alarms common with passive wireless ID tags, which can trigger simply by proximity.
By touching or standing in front of items they are interested in, consumers can get more in-depth information. Electronic exchange of business cards Communication can be kept private using authentication and encryption technologies. Automatic importing of personal address book and call history.

A network connection is initiated simply by placing a lap-top on the table. Using different sheet patterns enables segmentation of the table into subnets. Users can listen to music from a Red Tacton player simply by putting on a headset or holding a viewer.
Fig 5. Transmitter and receiver electrodes are covered with insulating films. No current flows into the body from the RedTacton transceiver. The focus on ubiquitous service has brought about the shortening of distances in communication. Red Tacton is positioned as the last 1m solution to ultimate close-range communication.
