Abstract
Human body communication (HBC) has the advantages of low power consumption, low radiation and anti-interference ability, which has broad application prospects in entertainment and health care. Accurate human channel characteristics will contribute to the development of HBC. This paper explores the effect of channel length and electrode size on human body channel phase characteristic. A galvanic coupling human body communication experimental platform was built. The measurement results show that in the low frequency band, the phase transition is less than the high frequency. When the frequency is in the range of 200 kHz to 300 kHz, the phase will oscillate. Increasing the electrode size can improve phase oscillation. This paper provides a reference for the application of human body communication in long channel and the miniaturization design of transceiver.
