Electrode Impedance Modeling for Channel Characterization for Intra-body Communication

This paper discusses techniques for modeling the electrode/human contact impedances for Intra-body communication applications. Factors that affect the electrode impedance are considered and tuned in order to study their impact on the channel model (gain/attenuation profile). Finally, an explanation is provided for the relation between the different basic impedances and blocks that are considered in the channel model, and the sensitivity of the channel gain to the variation in such parameters.
