The passive electrical properties of the living tissue are essentially important in biomedical measurements, and often expressed in the bioelectrical impedance. It is also well known that the bioelectrical impedance of the skin is subject to physiological and psychological fluctuations. However, a lot of phenomena, concerned with bioelectrical impedance, are still left unanalyzed. In this study, a new method of measuring bioelectrical impedance, not only its absolute value but also its real and imaginary parts or its phase angle, is introduced. Moreover, it is proposed that the time course of impedance changing is measurable corresponding to the change of mental and physical conditions. It is also proposed that new non-invasive methods of acquiring biological data are possible making use of the impedance measurement.
