A method for identification of the parameters of the nonlinear equivalent circuit of electric admittance of skin is proposed. The circuit is represented by parallel connection of power-polynomial approximated nonlinear admittance and linear capacity in the presence of free-form current signal. A hardware-software system for nonlinear electrical skin admittance measurement is described. The range of linear and nonlinear skin admittance components was estimated using this system and polynomial approximation of degree three for test audience skin reflexogenic zones. The suggested method of verification for parameter identification of electrical skin admittance nonlinear equivalent circuit is accomplished.
