Abstract All the user-friendly services require technologies that enable communication between people and objects are in close proximity. This paper describes a new technology for communication by touching called, a technology we call Red Tacton. It is a communication between mobile terminals and terminals that are embedded in the environment .The routing of cable is clearly inconvenient. When weal radio signals are used the data packets get collided which leads to lose of packets. In this technology the human area become the path of transmission. A transmission is formed automatically when a person comes into contact with a device and communication between mobile terminals begins. Here, the human body acts as a transmission medium IEEE 802.3 half duplex communication at 10Mbits/s.

Keywords Red Tacton, Human Area Networking, Communication through Touch Technology.

  1. INTRODUCTION

    In our modern world people can communicate anytime anywhere and with anyone with more convenient and in a simple way as we done in our real time. This technology that facilitate faraway communication with the people. Although many electronic devices had reduced. Wired connection between electronic devices in human area networks is easily tangled. Also the short range communication systems called Bluetooth also have some problems. Throughput is reduced due to packet collision and communication is not secure because signals are interpreted. The ultimate solution is the human area network to provide intra body communication, in which the human body serves as a medium of communication. This technology reduces the problem of throughput reduction, low security. The concept of intra body communication, which uses the minute electric field propagated by the human body to transmit information, was first proposed by first IBM. Red Tacton can be used for intuitive operation of computer-based systems in daily life, temporary one-to-one private networks based on personal hand shaking, device personalization, security and a host of other applications. With the Red Tacton system, we can envisage a future in which the human body acts as a non-stop conduit for information. The technologies had reported two limitation:1)The operating range through the body was limited to a few ten of centimeters 2) the communication speed was only 40kbits/s.

  2. HUMAN AREA NETWORK

    The electro-optic sensor combining an electro-optic crystal with laser light and recently reported an application of this sensor for measuring high frequency electronic devices. The electro optic has three key features: 1) It can measure electric

    fields from a device under test without contacting it, which minimizes measurement disturbances, 2) Ultra wide band measurement is possible, and 3) It supports one point contact measurement that is independent of the ground. NTT utilized this feature to fabric an intra-body communication receiver for its human area networking technology, which is called Red Tacton. The operating principle is illustrated below:

    Fig 1: Operating principle of Red Tacton

    We can represent the electric field induced towards the body by the transmitters signal electrode is represented by Ea. The system requires a ground close to the transmitter signal electrode, so the electric field Eb induced from body can follow a return path to the transmitter ground. Moreover, since people are usually people are standing on a floor or a ground, the electric field Ec escapes from the body to ground, mainly from the feet. The electric field Es that reaches the receiver is Es=Ea-(Eb + Ec). This change is detected by laser light and transformed into digital data by a detector circuit.

  3. TRANSMISSION STEPS

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

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

  3. It relies on th eprinciple that the optical properties of the electro-optic crystal varies according to the changes in the weak electric field.

  4. It detects the changes in the optical properties of an electro-optic crystal using an laser beam and converts the result into an electrical signal in a detector circuit.

    transceiver. When communication occur, displacement current is generated by the electrons in the body because the body is subjected to minute electric fields.

    Red Tacton subjects to the Radio Frequency Exposure Protection Standard (RCR STD-38) issued by the association of radio industries and business.

    1. FEATURES OF RED TACTON

      1. Touch

        It establishes the communication with just a touch which is the major feature of Red Tacton Device.

      2. Broadband and Interactive

        The transmission media is on our body surface, the speed does not get varies in congested areas where many people can communicate at the same time.

      3. Any Media

It is possible for the Red Tacton to work with any type of device.

          The signal from the interface is sent to the data sense circuit and the transmitter circuit. The data sense circuit senses the signal and if the data is present it sends control signal to the transmitter which activates the transmitter circuit. The transmitter circuit varies the electric field on the surface of our body. The change in the electric field is detected by the electro- optic sensor. The output of the electro-optic sensor is given to the detector circuit, which in turn given to the interface of the receiving Red Tacton device.

  2. HUMAN SAFETY

Although the transmission is taken place through human body it will not affect our health. Because the transmitting and the receiving electrodes of the Red Tacton receiver are covered with insulating film, so the body is perfectly protected. This makes it possible for the current to flow into our body from a
