Abstract
This paper presents a novel electrically isolated measuring system for evaluating signal attenuation on the human body and designing a stable MHz-band human-area network system that uses the surface of the human body as a data transmission path. We developed an electrically isolated probe consisting of an electrical-to-optical (E/O) converter and an optical-to-electrical (O/E) converter because there was a requirement for a tool to measure signal loss that did not affect our communication system. We modeled the communication path consisting of a transmitter, a receiver, and the human body. And we measured signal intensity to ensure an effect of the probe. As a result, the measurement system using an E/O and O/E conversion probe is effective to achieve a stable communication system.
