The Wearic wetness sensor can detect small amounts of water or other liquids and ice on its substrate. The most common measurement principle for textile wetness sensors is a resistance measurement between two conductive electrodes. The support fabric on which the electrodes are built is an insulating material (e.g., polyester, cotton, polypropylene).

In the “dry” state, the textile wetness ...
