Abstract
A moisture sensitive device includes a polymer capacitive moisture sensitive element and a heater. The polymer capacitive moisture sensitive element is formed by sequentially stacking a lower electrode, a moisture sensitive film made of an organic polymer resin material, and an upper electrode on an insulating substrate. The heater serves to heat the moisture sensitive film to restore the original characteristics thereof.
Claims3
A moisture sensitive device comprising:
- a polymer capacitive moisture sensitive element, having initial characteristics, formed by sequentially stacking, on an insulating substrate, a lower electrode, a moisture sensitive film made of an organic polymer resin material and an upper electrode;
- and
- heating means for heating said moisture sensitive film to restore said initial characteristics in said polymer capacitive moisture sensitive element when said characteristics drift from their initial state.
Dependencies are inferred from the claim text.
