Overview• Introduction• History of Redtacton• HAN• Working principle and procedure• Features• Applications• Advantages and Disadvantages• Conclusion

Introduction• RedTacton is a new human area networking technology that uses the surface of the human body as safe, high speed network transmission path.• RedTacton uses the minute electric field emitted on the surface of the human body.• It is developed by japanese technology NTT lab.

History• The concept of intra body communication was first

proposed by IBM in 1996.• The IBM technology had two limitations: The operating range through the body was limited to a few

tens of centimeters. The top communication speed was only 40Kbits/s!!.• These limitations were overcome by NTT(Nippon Telegraph

and Telephone Coperation) located in tokyo, Japan by using Photonic electric field sensors and finally in 2005 they came up with a HAN technology called “RED TACTON”.

Human Area Networks(HAN)

• HAN uses human body as communication network and uses the concept of Redtacton to transmit the data.

• HAN transmits the data between the human centered electronic devices and computers and other network devices via total human natural physical activities.

Working Principle• Redtacton is based on the principle that optical properties of electro-optic crystal can vary according to changes in electric fields.• Redtacton allows information to be exchanged

between two transceivers without the need for a server to store or process information.

CONTI……..

• Redtacton receiver and transceiver are two major devices in the transmission.• Redtacton majorly depends on the human natural physical movements.

Working Procedure• Transmitter sends data .• Transmitting transceiver creates a change in the field.• Field from human body dissipates into earth.• Electric field is received using sensing technology.• Receiving transceiver recognizes the change in the electric field.• Sensing technology measures the weak electric fields induced.• Electro-optical crystal uses laser to convert and read the signal.

Features Redtacton has three main functional features.

Touch:

• Touching, gripping, sitting, walking, stepping and other human movements can be the triggers for unlocking or locking , starting or stopping the device.

Broadband and Interactive:• Bandwidth does not deteriorate even with duplex

operation and simultaneous access by many years!

Duplex communication is possible. The transmission speed does not deteriorate in congested areas.

Any Media:• 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.

Applications1)Elimination of human error which means an alarm

sounds automatically to avoid accidental medicine ingestion.

2)Marketing application(context awareness) which means touch advertising and receive information.

CONTI……..

3)Personalization of mobile phones which means just touching a phone makes it your own.

4)Personalization of automobiles which means just sitting in the seat trigger the car to load all its presets, just the way you like.

5)User verification and lock management at entrances which means users verify’s and unlock with a touch.

Advantages • Data transfer is faster and easier through this

technology.• Data loss during transfer is less.• Use of minimum amount of power(of some milli volt

range) .• Security is more.

Disadvantages• Complex in design.• Too costly.• It can be useful within few centimeters only.

Conclusion• We conclude that, when we compare Redtacton with

other technology present today it can give a better performance over others.

• And we can say that to connect the network with in short distances Redtacton is best.

• In this technology there is no problem of hackers as our body itself a media.
