The method of making thin film humidity sensors uses thermal vapor deposition or drop casting techniques to fabricate nickel phthalocyanine-fullerene-based (NiPc-C) 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-Cis 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.

A method of fabricating and using of flexible elastic photo-thermoelectric or thermoelectric cells is being presented, where the thermoelectric materials have been used in nanohybrid (pristine form). The casing of the cells is made up of flexible elastic materials (plastic, rubber). The casing may have different shapes as rod, semi-circular, wave-form, spiral etc., that makes them easy for practical applications and the thermoelectric cells can potentially provide high efficiency. The flexible thermoelectric cells based on carbon nano-tubes (CNT) and its blend with cobalt oxide/graphene oxide nanohybrid have been made and tested.

The method of making a flexible elastic conductive material for strain sensor and resistance applications using rubbing-in technology is shown. The thin rubber or any conductive material (substrates) is fixed at strained condition on the solid plate, by rubbing-in technology. Nanopowder of nanomaterials (organic semiconductors, carbon nanotubes, copper doped tin oxide, manganese doped tin oxide) at room temperature are embedded into the rubber conductive material to make built-in structure of conductive flexible elastic substrates that can be used for strain sensors, gages and resistance applications. The resultant product showed good sensitivity, stability and reliability during and after the rubbing-in operation.
