Model of the Current-Voltage Relation for a Skin Pore

摘要: Using a Nernst-Planck model, we show that the current density in membrane’s pore as function of voltage has three types behavior: quasi-ohmic behavior at low voltages, with small slope, non-ohmic linear dependence large and nonlinear transition region intermediate voltages. The magnitude from voltages depends mainly on height energy barrier inside pore, w, through an exponential term, e w . domain is experimentally accessible almost unexplored, despite fact it can offer direct information about pore. model only two assumed parameters, height, relative size entrance r, clear physical meaning, important advantage for fitting interpreting experimental data. This simple current-voltage nonlinearity good starting point explaining electrical skin
