COMMUNICATION DEVICE AND METHOD USING HUMAN BODY

摘要

A communication method and a communication device using a human body are provided to minimize a signal loss by adjusting arrangement directions of signal electrodes and ground electrodes according to a signal transmission direction. A communication device using a human body includes an electrode unit, electrode selection switches(540,545), a transmitter(510), and a switch controller(555). The electrode unit includes at least one electrode pair having a signal electrode(530) and a ground electrode(535). The electrode pairs are arranged in at least one direction. The electrode selection switches select one of the electrode pairs. The transmitter outputs data signals to the human body through the selected electrode pair. The switch controller transmits a test signal to another communication device, which is connected to the communication device through the human body, through the electrode pairs, and a signal loss is measured. The switch controller controls the electrode selection switch to select the electrode pair with the minimum signal loss.
