• Red Tacton is a new human area network technology.• It gives us safe and high speed network transmission.• RedTacton is a technology developed by Japanese company Nippon Telegraph and Telephone Corporation (NTT) • 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.

Introduction

• RED TACTON meaning: tacton: touch-act-on (action triggered by

touching) red: symbol of warmth and love

conveying the cordiality of interpersonal communications

• Red Tacton works on HAN. (Human area networking)

• Red Tacton uses the surface of the human body as a safe, high speed network transmission path.

• Red Tacton uses the minute electric field emitted on the surface of the human body for the data transfer.

What is RedTacton

Transmits data utilizing body’s electric fieldThe body becomes its own Ethernet cable

High speed – up to 10 mbpsVery secure

Uses a Uses a transmitter and transmitter and a receiver, or a a receiver, or a transceiver, transceiver, which provides which provides both functionsboth functions

Red Tacton – Working Principle

Point to 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

Working Mechanism

• 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

Red Tacton Transceiver

Features

Touch

Communication with just a touch or stepTouching, gripping, sitting, walking, stepping and other human movements can be the triggers for unlocking or locking, starting or stopping equipment, or obtaining data.

Broadband & Interactive

Because the transmission path is on the surface of the body , transmission speed does not deteriorate in congested areas where many people are communicating at the same time

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.

Safety

•Electric field intensity is less than 82.4 V/m • Displacement current is less than 45mA at a frequency of 10MHz.

Applications One to One Services

Intuitive operation of Personal Information

Device Personalization

New behavior patterns

Marketing Applications

Security Application

Military Applications

Prototype Devices

Advantages & Disadvantages

Advantages•Data transfer is faster and easier through this technology.• Data loss during transfer is less.• Use of minimum amount of power (of some mili volt range).• Security is more.Disadvantages• It can be useful within few centimeters.• Effects on human body is still under research.
