Abstract

The electrical impedance of a living tissue reflects its cell construction and physiological activity. For this purpose we developed an automatic sensing device of electrical tissue characteristics. The system is composed of a part measuring impedance at multifrequency points and a part analyzing parameters of dispersion of bioelectrical impedance, impedances are measured at eight frequency points of 1 kHz-500 kHz. The parameters for Cole-Cole arc´s law are determined automatically by a personal computer program
