Measurement results of human body's signal loss with multiple subjects for human body communication

Human body communication is being recognized as a new communication technology that can replace wire and wireless technologies in a body area network (BAN). In this approach, the body is used as a medium for transmitting data between mobile devices or between a mobile device and a peripheral device. A user simply touches the devices, and then the devices are connected to each other via the body of the user, and they can then communicate without using a wire or wireless technology. This paper presents a measurement result on signal losses of the human body. Signal losses were obtained from measurements of multiple subjects. In the measurements, the grounds of a transmitter and a receiver were properly isolated from each other and from the earth ground for an accurate measurement. Finally, channel properties were analyzed by using the measured signal losses.
