Effects of ground electrode on signal transmission of human body communication using human body as transmission medium

Abstract

In this paper, the measurement results on the effects of ground electrode according to the transmission distance are presented. A biological tissue-equivalent phantom has been used in the measurement of a previous paper, but a real human body is used in this paper. Also, the measurement results are analyzed by EM simulation. In the previous papers K. Fujii et al. (2003)-(2002), the simulation model for human body has been composed of only muscle tissue. In this paper, a more accurate model composed of muscle and other tissues is used during the simulation. Finally, the method by which a ground electrode can be used more efficiently is proposed based on the measurement results
