DATA TRANSFER THROUGH SKIN


  DATA TRANSFER.ppt (Size: 789.5 KB / Downloads: 0)

INTRODUCTION

Mobile & Internet networks are used for transmission over distant terminals but not a right option for transmission between wearable devices and other embedded systems.
Drawbacks in blue tooth & WAN in crowded places ,made to use INTRABODY COMMUNICATION ,in which the body is used as a transmission medium.
The concept involves transmission of minute electric field through body.
The technique is called ELECTRIC FIELD PHOTONICS , where a laser is used to detect the variation of the electric field and converted back.

HUMAN AREA NETWORKING

Electro-optic sensor combining Electro-optic crystal with laser is used.
Key features of SENSOR:
measure electric field from device without contacting it.
ultra wide band is possible.
one point contact measurement ,independent of earth.
Ea is electric field induced through body by transmitter signal electrode, this require a ground close to electrode.
Eb can have return path to transmitter ground.
Ec escape from body to ground through feet.

HUMAN SAFETY

Electrodes are covered by insulating films , preventing body from flow of current.
Electrons in body generate displacement current because it is subjected to minute electric fields.
This current intensity is far below safety limit given by “Radio frequency-exposure protection standard(RCR STD-38)issued by “Association of radio industries and business(ARIB)”.

conclusion

They are easy to use but they are still under study.
The technology like Redtacton is under development.
Our human body has the hardware and software to be used over a large network and this interface is under experimental stage.
