A body impedance measurement apparatus and method as well as the transmitter and receiver of a body impedance measurement apparatus are provided. A body impedance measurement apparatus includes transmitter means configured to provide an amplitude modulated signal via a transmitting electrode means to a body to which the transmitting electrode means is applied. The body impedance measurement apparatus also includes receiver means for receiving signals, responsive to the amplitude modulated signal, via a receiving electrode means that is configured to be applied to the body and to be remote from the transmitting electrode means so as to be a wireless communication with the transmitting electrode means via the body. The receiver means is configured to process the received signals to determine a measure of the body impedance.
