Matching network to improve the transmission level of capacitive intra-body communication (IBC) channels

Abstract

The method of conjugate-image impedance is used to design the matching network for the capacitive intra-body communication channel. Narrow passbands around 20 MHz are observed in the measured responses of the matched cases, where the transmission levels are about 20 dB higher than the unmatched ones. The method versatility is also validated.
