The application of a cathodic precipitation technique for the generation of films of alumina precursors at a hydrogen sorbing palladium electrode to the manufacture of humidity sensing materials is reported. The response to changing atmospheric humidity of a device fabricated by this electrochemical method has been compared to that of a commercially available sensor. AC impedance techniques have been employed to probe the electrochemically generated sensor's conduction mechanisms at various humidity levels, and an equivalent circuit model has been proposed for the device.
