Studies of wearable computers have attracted public attention in these days. And one of the area of interest is the communication system adopted in those wearable computers. As an example, wearable devices which use the human body as a transmission channel, have been developed. However, little is known about the transmission mechanism of such devices in the physical layer. In this paper, we proposed calculation models of the transmitter and the receiver attached to the arm using the FDTD method. From this model, we estimated the difference in the received signal level due to the electrode structures of the transmitter and the receiver under various conditions. Moreover, in order to verify the validity of these calculation models, we compared the calculated received signal levels to the measured ones by using a biological tissue-equivalent phantom.
