Analysis of Channel Characteristic for Body Channel Communication Transceiver Design

Abstract

In this paper, body channel communication and its channel characteristic are investigated through measurement. Previously, the body channel communication has limitation in channel bandwidth due to its fluctuation. To verify orientation, 4 independent systemic factors are under test; (1) the size of the signal electrode attaching on the skin, (2) the size of the ground plane (GND) electrode that is not attaching on the skin, (3) the channel distance between TX and RX through human body, and (4) the length of cable connecting between the transceiver hardware and signal electrode. The size of the electrode and channel communication does not have a high correlation, However, the cable length between electrode and device shows a large variation. The newly proposed results are useful for hardware design and allow larger utilizable channel bandwidth that is promising for future BCC hardware design.
