Abstract
A sensor device is for determining moisture using an electrical conductivity measurement. A non-conducting support has individual electrical conductors. The electrical resistance between the electrical conductors is dependent upon the amount of moisture present on the support and the electrical conductors. The respective electrical conductor is an integral component of a hook-and-loop fastener part.
Claims22
A sensor device configured for determining moisture using an electrical conductivity measurement, comprising:
- a non-conducting support which has individual electrical conductors;
- and
- wherein an electrical resistance between the individual electrical conductors is dependent upon an amount of moisture present on the support and the individual electrical conductors;
- wherein a respective electrical conductor is an integral component of a hook-and-loop fastener part;
- wherein the hook-and-loop fastener part is made of a base fabric, made of warp and weft threads, through which passes, at least partially, at least one functional thread which partially forms fastener elements protruding above the base fabric, and in that the respective electrical conductor is woven into the base fabric as a respective further functional thread.
