Abstract

The electrical impedance of a living tissue reflects its cell construction and physiological activity. For this purpose was developed automatic sensing device of electrical tissue characteristic. The system is composed of a part measuring impedance at multi-frequency points and a part analyzing parameters of dispersion system of bio-electrical impedance. Electrical impedances are measured at eight frequency points between 1 kHz to 500 kHz. The parameters for Cole-Cole arc´s law are determined automatically by personal computer program. If the cell constant dependent electrode size and electrode form are given, resistivity and dielectric constant can be calculated
