Surface Resistance is the measure of currents per voltage. Surface Resistivity, the electrical property of a material, follows from multiplying the factor 53.4 times Surface Resistance. We tested the Surface Resistivity of different samples in which some
were doped and undoped. Our studies showed that the doped samples had a higher sensitivity to the different voltages and temperatures that were applied, than the undoped samples. Therefore, we can conclude that the Doped PVA films would be more efficient in use for different IR, (infrared) Chemical, and Motion sensors.
