We may have imagined the future as a place crawling with antennas and emitters, due to the huge growth of wireless communications and it gives an idea of using our body as a data transmission. Thus NTT labs, the Japanese telecom group had developed a revolutionary technology called “Red Tacton”.
“Red Tacton” gives a whole new meaning to the term “networking”. It is a new Human Area Networking technology which uses the surface of the human body, as a safe and high speed data transmission path. Red Tacton is a new technology that is completely different from wireless and Bluetooth or Infrared, as it does not rely on electromagnetic or a light wave to transmit data, also users can narrowly limit signal recipients rather than broadcasting to all devices within given range . It makes use of weak electric fields on the surface of the body. Here, the human body acts as a transmission medium supporting IEEE 802.3 half-duplex communication at 10Mbit/s.
Focusing on the natural feeling of life, inevitability and sense of security conveyed by touching, Red Tacton (Red-Warmth, T-Touch, and Acton-Action) lets people transfer data to each other by means of handshake or a slap on the back and relief by touching in daily life.
A transmission path is formed at the moment, when a part of the human body is get contact with a Red Tacton transceiver. On separating the ends, the contact between the receiver and body, ends the communication. The Red Tacton chips, which will be embedded in various devices, contain a transmitter and receiver build to send and accept data stored in a digital format. The chips can take any type of file such as mp3 music file or mail and convert it in to the digital format (in the form of digitals pulses) that can be passed and read through a human being. The chip in receiver decodes these tiny pulses and converts the file back into its original form. The main component of the transceiver is an electric-field sensor implemented with an electro optic crystal and laser light.
Through Red Tacton our body can be used for linking our mobile phone or MP3 player to a cordless headphone, digital camera to a PC or printer, and all the accessories we carry around. This network linking is possible using any body surfaces, such as the hands, fingers, arms, feet, face, legs,etc . Red Tacton works even through shoes and clothing. Using Red Tacton enable devices, music from our digital audio player in our pocket would pass through our clothing and suits over our body to headphones in our ears. Instead of fiddling around with the cable to connect your digital camera to your computer you could transfer pictures just by touching the PC while the camera is around your neck and since data can pass from one body to another you could also exchange electronics business cards by shaking hands, trade music files by dancing cheek to cheek or swap phone numbers just by kissing.

RedTacton is a new Human Area Networking technology that uses the surface of the human body as a safe, high speed network transmission path. The name “Tacton” has originated, as the technology involves touch and action. The word “red” indicates warm and cordial communications.
TECHNICAL APPROACH OF REDTACTON:
RedTacton takes a different technical approach. Instead of relying on electromagnetic waves or light waves to carry data, RedTacton uses weak electric fields on the surface of the body as a transmission medium. A RedTacton transmitter couples with extremely weak electric fields on the surface of the body. The weak electric fields pass through the body to a RedTacton receiver, where the weak electric field affects the optical properties of an electro-optic crystal. The extent to which the optical properties are changed is detected by laser light which is then converted to an electrical signal by a detector circuit.
HOW RED TACTON WORKS??
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.
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.
5) Security applications:
RedTacton 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.) could be logged by the security system.

1.1 WHAT IS REDTACTON?
Human society is entering an era of omnipresent computing, when networks
are seamlessly interconnected and information is always accessible at our fingertips.
The practical implementation of omnipresent services requires three levels of
• Wide Area Networks (WAN), typically via the Internet, to remotely connect
all types of severs and terminals;
• Local Area Networks (LAN), typically via Ethernet or WiFi connectivity
among all the information and communication appliances in offices and
• Human Area Networks (HAN) for connectivity to personal information, media
and communication appliances within the much smaller sphere of ordinary
daily activities-- the last one meter.
HISTORY OF HAN
In the past, Bluetooth, infrared communications (IrDA), radio frequency ID
systems (RFID), and other technologies have been proposed to solve the "last
meter" connectivity problem. However, they each have various fundamental
technical limitations that constrain their usage, such as the precipitous fall-off in
transmission speed in multi-user environments producing network congestion.
• The concept of intra-body communication was first proposed by IBM in 1996.
• This communication mechanism was later evaluated and reported by several
research groups around the world.
OVERVIEW OF REDTACTON
• RedTacton is a new innovative Human Area Networking technology that
turns the surface of the human body as a safe, high speed network
• RedTacton takes a different technical approach. Instead of relying on
electromagnetic waves or light waves to carry data, RedTacton uses weak
electric fields on the surface of the body as a transmission medium.
• 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.
• Communication is possible using any body surfaces, such as the hands,
fingers, arms, feet, face, legs or toes. RedTacton works through shoes and
clothing as well.
