Effect of Electrode Size on Signal Attenuation in Intra-Body Communication

Article Preview

Abstract:

In the galvanic coupling intra-body communication, transmitting and receiving of signals require coupling between electrodes and human tissue. Electrode size has a direct effect upon signal attenuation so as to influence signal transmission. To analyze the exact effect of electrode size on signal attenuation, the volume conductor model of human forearm is built with COMSOL Multiphysics 4.2a.It can be found from the simulation experiment that, signal attenuation declines with the increase of electrode size, which lays the foundation for subsequent experiments.
