Method and apparatus for communication between inside and outside of transmission medium such as human body utilizing itself as a communication line

The present invention damage to the medium by to receive it by as the medium for communication methods and apparatus for medium naeoegan using a communication line, in particular, by placing the transmitter within the medium, energizing the electric signal the transmitter via the medium without causing, the present invention relates to a medium for improving the reception of signals in a communication method and apparatus using the medium naeoegan communication line. The communication method of the medium using the present inventors naeoegan medium as a communication line comprising the steps of receiving an electrical signal containing information regarding the medium from a number of sensors in the internal medium and; And the step of energizing the electrical signal directly to the medium; Medium and a step of detecting the electric signals flowing to the outside. The invention without causing damage to the media, there is an effect that it is possible to reduce the power consumption in the transmitting step and downsizing solve the directional problem of the antenna, and.
