The method of making thin film humidity sensors uses thermal vapor deposition or drop casting techniques to fabricate nickel phthalocyanine-fullerene-based (NiPc-C60) quick response humidity sensors with negligible hysteresis. Prior to the deposition of aluminum electrodes, a glass substrate is cleaned by using acetone in an ultrasonic bath for 10 minutes. After cleaning, the substrate is washed with de-ionized water and then dried. A gap is created between two electrodes by masking the glass substrate with copper wire. This assembly is plasma-cleaned for 5 minutes in a thermal evaporator. Subsequently aluminum (Al) thin films are deposited on the assembly. Next, a mixture of equal parts NiPc-C60 is deposited onto the gap between the Al electrodes by thermal vapor deposition or by drop casting. A method of forming NiPc-graphene oxide (NiPc-GO) humidity sensors without using instrumentation drop casts an NiPc-GO suspension onto aluminum foil electrodes taped to a substrate.
