In this paper, we report on time domain reflectometry (TDR) and transmission (TDT) measurement and characterization of skin using biosignal electrodes, normally used for monitoring of EMG biosignals. Basic principles of TDR and TDT methods are presented for various skin equivalent circuit configurations. Using the methods, the reflected and transmitted waves were measured at three different parts of the human body skin. The measured differences reveal differences in transient phenomena related to charging-discharging cells in a skin and underneath layers.
Keywords: Time domain reflectometry, reflection, transmission, biosignal electrodes, transmission line
