Sensor device
First Claim
1. A sensor device including a resistance layer arranged on a substrate, the sensor device having a moisture-sensitive hydrophilic surface, the sensor device comprising a plurality of interdigital electrodes with recesses formed between the interdigital electrodes, the surface comprising thaw-detecting condensation cores sintered onto the interdigital electrodes and the recesses, wherein the recesses extend through at least a portion of the resistive layer and at least a portion of the substrate.

Abstract
A sensor device is provided for detecting thawing on surfaces with interdigital electrodes formed in a resistance layer which is formed on a substrate. In order to develop the sensor device further so that the measuring speed of the sensor device is further increased, the disclosure proposes that the interdigital electrodes and recesses between the interdigital electrodes have a moisture-sensitive hydrophilic surface through condensation cores applied to it.
