Human body communication system and communication device
First Claim
1. A human body communication system for communicating data via an electric field formed by intervention of a human body, said human body communication system comprising:
- a transmitter for generating said electric field by transmitting a potential difference signal corresponding to transmission data from a transmitting electrode; and
a receiver for receiving the data by reading the potential difference signal in said electric field by a receiving electrode;
wherein said transmitter and said receiver use the potential difference signal in a frequency band such that a quasi-electrostatic field formed within the human body is dominant over a radiation field formed outside the human body when said transmitting electrode and said receiving electrode are each disposed in very close vicinity to the human body.
