Pulsed polarization measurements were performed on Pt | YSZ sensors. These consist of four interdigital electrodes (IDEs), two on the upper and two on the lower side of the YSZ-substrate. IDEs with an electrode gap and width of 150 and 300 μm were tested. The sensors were operated one-sided and double-sided. It was found that the sensors operated on one side showed a significantly better symmetry in the signal path. This symmetry, in turn, makes it possible to halve the measuring time. In general, the sensitivities were very similar in all operating modes and show no dependency on the investigated gap.
