How to describe the skin’s electrical nonlinear response

Abstract

The skin’s electrical nonlinearities found experimentally arerelated to stratum corneum and modeled by the parallel resistance (Rp) as a linear current dependence in conductance (1/Rp). We show that such dependence could occur because the skin’s current-voltage characteristic has a non-ohmic linear portion at large voltage, due to pores’ conduction, that can be detected as a constant dynamic resistance (dU/dI).
