Sažetak
Construction and testing of thin-film capacitive relative-humidity sensors, using a polymer film as dielectric, are presented. Methods of deposition of the upper electrode, which must have proper electrical conductivity and be porous to assure a quick response to changes of relative humidity in the environment, is discussed. The upper electrodes were deposited by vacuum evaporation of Ni, Cr and Ni-Cr alloy. The angle of incidence of evaporated material was varied with the aim to change porosity and, therefore, the response time.
