Description of a method for the measurement of electric skin impedance.

A device for analysis of electric skin impedance has been build, which determines quantitatively the constituents of electrical skin model as proposed by Philipson. It measures impedance modulus and phase angle with different frequencies, then it calculates impedance skin locus on complex plane. In this pattern the choice of frequencies is not critical. It can work with two, three, or four electrodes. Precision achieved and great simplicity of use, allows it ideal for clinical applications, despite the theoretical complexity of measurements.
