Claims
- 1. The method of producing a moisture sensitive electrically resistive element capable of detecting and measuring moisture variations and content under ambient conditions ranging from 0 to 100% relative humidity which comprises:
- providing a substrate made of electrically non-conductive material;
- depositing first and second electrodes on said substrate in a spaced relationship to each other; and
- depositing a moisture sensitive film comprising a polymeric material having a formula:
- [--CH(C.sub.6 H.sub.4 SO.sub.3 X)--CH.sub.2 --].sub.n
- wherein X is any one of a hydrogen atom, metal atom, ammonium, urea, triethylenediamine, tetramethyleneguanidine and hexamethylenediamine wherein n is qreater than 50;
- such that said resulting electrically resistive element has quick response to said broad humidity change to vary its internal ohmic resistance.
- 2. A method of detecting and measuring moisture variations and content under ambient conditions utilizing a highly moisture sensitive electrically resistance element which comprises:
- providing a highly stable moisture sensitive electrically resistive element capable of detecting and measuring moisture variations and content under ambient conditions ranging from 0 to 100% relative humidity comprising a substrate made of electrically non-conductive material, first and second electrodes superimposed on said substrate in a spaced relationship to each other and a moisture sensitive film comprising a polymeric material having a formula:
- [--CH(C.sub.6 H.sub.4 SO.sub.3 X)--CH.sub.2 --].sub.n
- wherein X is any one of a hydrogen atom, metal atom, ammonium urea, triethylenediamine, tetramethyleneguanidine and hexamethylenediamine wherein n is greater than 50; and
- introducing said element into a moisture variable environment, said electrically resistive element responding quickly to said broad humidity range to vary its internal ohmic resistance.
