Voltage distribution of two thin polymeric film surface resistance measurement systems

Two different methods for measuring the surface resistance of thin polymeric films are presented. The first method is the standard method and utilizes concentric ring metal electrodes. The second one is a novel method and uses instead concentric cylindrical metal electrodes. Both have been studied analytically and experimentally. The voltage distributions that are developed in both methods are calculated, plotted using three-dimensional graphs, and finally compared in order to analyze the advantages and disadvantages of the two measuring systems (acetate is the dielectric). The cylindrical electrodes, which give lower stresses around the outer electrode, seem to be more suitable for the measurements of the surface resistance of thin polymeric films
