Abstract

We propose a signal channel model that involves using a wearable transmitter for an intra-body communication system. The impedance components regarding the wearable transmitter were added to our previous noise channel model to construct new model. The transmitting voltage through the human body was measured at the embedded electrodes by using a spectrum analyzer and compared with the circuit simulation. We found that the impedance components between the human body and the embedded electrodes agree with experimental results. However, the experimental results from between the wearable transmitter and human body differ from those of the circuit simulation. This means that the capacitance between the wearable transmitter and human body should be measured precisely.
