An interdigital H2O sensing structure applied on a ceramic element provides the possibility to determine the water condensation process in the exhaust system of an internal combustion engine during cold-start. In lab tests, a clear correlation between capacity change and water droplet size was found. In engine cold start tests it was proven that the start and the end points of the water condensation processes can be detected.
