Abstract
A sensor format is based on impedance analysis of polymer coatings of electrodes. A detectable signal is produced by the effect of a reactive or catalytic species at or very near the polymer coated electrode. The reactive or catalytic species directly or indirectly effects a reaction with the polymer layers, whereby the polymer layer becomes porous and thus causes a measurable change in electrical properties of the electrode surface.
