  • Patent number: 4337658
    Abstract: A humidity sensor having an extended impedance range extending up to 10.sup.12 ohms precludes leakage currents. The sensor is in the form of an insulating substrate having conductive film such as gold applied to a surface thereof. The perimeter of a first film is completely encompassed by but spaced from a second film on the surface of the substrate. A humidity responsive layer of iron oxide is applied over the film layers to bridge the spacing therebetween in a continuous manner. Electrical terminals are connected, respectively, to the two films to provide a readout in terms of humidity.
