Theoretical Model for the Electrical Resistance of Skin

The kinetic change of electrical resistance of hairless mouse skin as a function of ionic strength of the bathing medium was determined from impedance measurements. After increasing (decreasing) the ionic strength of the bathing medium, resistance decreased (increased) continuously with time, finally reaching an equilibrium value. We have modelled this process, using nonsteady-state diffusion kinetics. The results show semi-quantitative correlation between theoretically derived and experimentally obtained values. Overall, this work provides further mechanistic insight into ion-conduction through the skin.
