Electromagnetic Field Analysis of Human Body Communication between Wearable Device Mounted on Human Arm and Stationary Equipment Considering Effect of the Earth Ground

Abstract

　Investigating the human body communication between a wearable device mounted on the human arm and a stationary equipment on or without the earth ground, we have reported the transmission characteristics and the electric field distributions around the human body and the stationary equipment on or without the earth ground. We have also shown that those characteristics and field distributions were different between the case with or without the earth ground. In this paper, the surface current distribution on the human body and the stationary equipment on or without the earth ground were numerically analyzed, and the relationship between the surface current distribution and the transmission characteristics were investigated and clarified.
