Abstract :
In this paper, we analyzed the effects of the ground electrode, especially the reverse effect in which the signal loss increases by the ground electrode. We measured how the signal loss varies in relation to the ground electrode. Furthermore, we simulated the current distribution to analyze the effects of the ground electrode. In other papers, the body has an artificial posture in which two arms and a shoulder formed a straight line. In our approach, we measured the signal loss of a person with a natural posture for actual human body communication; that is, the person´s two arms and shoulder did not form a straight line. Also, we reflected the modified posture of the body in the simulation model.
