Sensitivity of Galvanic Intra-Body Communication Channel to System Parameters

Abstract

In this paper, we investigate the sensitivity of the galvanic coupling Intra-Body Communication (IBC) channel to the variation of the basic parameters - being them electrical, geometrical or biological - of the main blocks of the IBC system; the transmitter and receiver nodes, the electrodes used, and the communication channel itself being the human body in this case. The study is performed over the frequency range 100 kHz–100 MHz, providing the system designer with a unique guide for the relationship between the system parameters, thus facilitating the design of an efficient and better matched system components.
