Abstract

Intra-body communication has a serious problem with the noise via the human body. In this system, the noise via the human body is transmitted along the same path as a signal because of capacitance coupling among nodes. These are transmitted in a coordinate phase as common-mode, but the distinction between the signal and noise is difficult. We present an analysis of the noise from an approach to clarify the method of measurement. A measurement of the noise was done by assuming the noise source via the human body and an electric light. To determine the noise to maintain the influence in a signal electrode, we connected an additional electrode to a ground electrode. The noise level was almost unchanged. Thus, the noise was influenced more by the signal electrode than by the ground electrode in this measurement system
