Summary:
We studied MHz-band communication between a TRX on the surface of the human body (wearable TRX) and a TRX embedded in the environment (embedded TRX). In this work, we propose a medical application to take advantage of MHz-band characteristics on the human body by embedding a TRX into the human body (in-body TRX) and examined the feasibility of in- and on-body communication. We also fabricated an electrically isolated probe (E/O-O/E probe) because conventional probes overestimate the received signal due to additional capacitance. The E/O-O/E probe eliminates this additional capacitance and can measure the received signal precisely. We measured the path loss around a phantom equivalent to a human and found that the proposed application is very useful in terms of engineering output power and received sensitivity.
