Conveying information through

exchange of thoughts , speech ,

visuals etc.,

Usually occurs between a sender and a

receiver.

Communication

Wired communication

Wireless communication

Electronic Communication

LAN cables ,OP fibres

Bluetooth,infrared port

Wifi,Gifi,Zigbee,NFC

Present Technologies

Wired communication though interception is difficult and

security is high people often find it cumbersome and

enangle.

Wireless communication creates connections when signals

arrive, allowing for easy connections because

connectors are unnecessary. However, seen from

another aspect, the arriving signals can be intercepted,

so security becomes an issue.

Problem With Present Technologies

WHAT DO WE DO TO OVERCOME ??

Developed by NTT

• Red-T-acton: Red = a warm color

T = touch

Acton = action

• technology belonging to HAN (Human Area Network)

• RedTacton technology promises to transfer data between computers and the human body at 10Mbit / s

• IEEE – 802.3

Basic Concept

Intra body communication methods

There are 2 basic methods:

• Electric current method

• Electric field method( Redtacton)

When electric current method is used the whole current is lost to the ground, so we cannot use electric current method. This also goes to the electric field method.

Proposed by IBM and it had two limitations.

Problem With Electric Current Method

One Point Network

Transceivers exchange

information – no server

Optical properties of electro-optic

crystal –varies based on electric

field

Data received using photonic electric field sensor combined with electro-optic crystal and laser light

HOW IT WORKS

WORKING OF TRANSCEIVER

Working Of Transceiver

INTERFACING WITH HUMAN BODY

HUMAN SAFETY

RedTacton device is fully insulated.

So the current wont flow inside a persons body

Displacement currents are induced due to weak

electric fields which are common in every day

life.

RedTacton conforms to the “Radio Frequency-

Expo- sure Protection Standard (RCR STD-38)”

issued by the Association of Radio Industries

and Business- es (ARIB). The levels produced

by RedTacton are well below the safety limit

specified by this standard.

FEATURES

APPLICATIONS

Our future of communication is more between

machines than humans itself.

So this technology will help paving the way for

the future technology by making our lives easy.

Since RedTacton electric field can pass

through conductors and dielectrics we can

believe without any doubt that this is the future

our technology.
