Patent attributes
Disclosed herein is a human body communication system for communicating data via an electric field formed by intervention of a human body, the human body communication system including: a transmitter for generating the 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 the electric field by a receiving electrode; wherein the transmitter and the 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 the transmitting electrode and the receiving electrode are each disposed in very close vicinity to the human body.
