The transmission path of intra-body communication is composed of capacitance coupling among nodes. In this work, we used four nodes: body, signal and ground electrodes, and floor ground. It was reported that intra-body communication is affected by common-mode noise. As the impedance balance of the transmission path deteriorates, common-mode noise increases. The impedance elements can be replaced with the capacitance elements. We assumed approximate equations of capacitance elements and investigated them by changing the distance among the four nodes. We propose a 2-step procedure for estimating the equations of capacitance elements. It is confirm that the simulated results based on our model agree with the experimental results regarding common-mode noise, which validates the model.
