Human Area Networking (HAN) is a technology that safely turns the surface of the human body into a data transmission path at speeds up to 10 Mbps between any two points on the body.
HAN Technology ,Transmitting data usingelectric field on the surfaceof the body
Transmitter induces a weak electric field on surface of the body. Receiver senses changes in the weak electric field on the surface of the body caused by the transmitter. Optical properties of Electro-optic crystal vary according to the changes of a weak electric field. Changes in the optical properties of an electro-optic crystal is measured using a laser and converts the result to an electrical signal in a optical receiver circuit
Communication starts when terminals carried by the user orembedded in devices are linked in various combinations throughPHYSICAL CONTACT according to the human’s naturalmovements.
Duplex, interactive communication is possible at a maximumspeed of 10Mbps
Human body, various conductors and dielectricscan be used as transmission media.

The evolution of RedTacton, technology is a big achievement, which will likely be targeted for use in applications such as wireless headset, medical application , security applications, wireless transmission by applyingdifferent actions. No Problem of Hackers User convenience is vastly enhanced Speed Enhance,ment for short distance Communication, of about 10Mbps Electric-field communication is secure because it does not emit signals over a wide area, unlike wireless communication.
For long term plans the size of the transceiver should be reduced. NTT is committed to quickly identifying and opening up those application areas with the most commercial promise for RedTacton , a business development process to be coordinated under NTT’s Comprehensive Product Function program RedTacton looks remarkably like a big pot of kryptonite is said to allow over 200kbps of data through th10 human hands or feet. Telecom giant Nippon Telegraph and Telephone Corp (NTT) is planning a commercial launch of a system to enter rooms that frees users from the trouble of rummaging in their pockets or handbags for ID cards or keys.

Lets use this meeting room to demonstrate how authentication is implemented.With conventional ID card authentication systems, ID cards must be waved over a touch plate each time you want to access a room.With this electric-field communication touch plate, however, communication andauthentication can be intuitively implemented in the natural flow of office activity. This card you see here is a transmitter on which my information has been registered.To use the system, all I have to do is put the transmitter in my pocket or bag. Now lets see what happens when I touch the plate.When I make contact, the lamp at the top of the touch plate changes color and authentication is instantaneously implemented. Information is transmitted via the electric field generated on the surface of my body, so authentication is possible even if the transmitter is in a bag, as Ive done here.However, if the transmitter is not contacting the body, such as when I put the bag down, authentication is not executed. Electric-field communication is secure because it does not emit signals over a wide area, unlike wireless communication. Of course, it also can be used for control similar to conventional security systems.If a user is holding a transmitter that does not have access authority, that user cannot gainto the roommatter how many times they touch the plate. The system can be tailored to meet a companys special needs, such as a grip-type system built into a doorknob or a step-type system embedded in a floor.
