(a) EQS-HBC Measurement set-up with the shielded transmitter in the wrist (device arm) and (b) its corresponding circuit model. The impedances for the skin and tissue layers26 are modelled, along with the signal sources, copper electrode coupler (band) and the measurement probes, to form the complete circuit model for EQS-HBC. Note that the probe is directly connected (d = 0) to the human body to measure the signal level from the source of the leakage. The EQS-HBC received voltage is measured from the fingers of the device hand.
