Abstract
A resistance-based humidity sensor including a moisture sensitive composite comprising a cellulose acetate and copper(II) oxide and a first electrode and a second electrode each in direct contact with the composite. Each electrode is connected to a circuit which can correlate a resistance of the composite to a measurement of a relative humidity. The method by which the sensor may measure a relative humidity in an environment includes applying a frequency through the first electrode, across the moisture sensitive composite, and through a second electrode to measure a change in the frequency that correlates to a resistance of the moisture sensitive composite and correlates to the relative humidity of the environment. A method of producing a resistance-based humidity sensor in the form of a film or in the form of a cell.
