The impedance spectroscopy method is unique in its ability in the investigations of conduction and polarization phenomena in testing material, which are connected with the structure of the material and its variation. In this paper, we propose the application of the impedance technique for the investigation of pathological changes of porpoise skin. The impedance measurements were performed using a frequency response analyser (Solartron Schlumberger 1172) covering a broad frequency range from 10^-4 Hz to 10⁴ Hz.
