Abstract: The present disclosure generally relates to the field of resistive sensing. In particular, the present disclosure relates to a highly sensitive reduced graphene oxide-nickel (RGO—Ni) composite based fast response temperature sensor. Aspects of the present disclosure provide a method for fabrication of a highly sensitive reduced graphene oxide-nickel (RGO—Ni) composite-based temperature sensor. An aspect of the present disclosure provides a temperature sensor comprising: a substrate; and a composite film deposited onto said substrate, wherein the composite film comprises a reduced graphene oxide-nickel composite film. In an embodiment, the temperature sensor is cryo-compatible.

Abstract: A nanocomposite has reduced Graphene oxide and silver nanoparticles. A method synthesizes a nanocomposite and fabricates a nanocomposite film on a substrate for sensor applications based on the principle of negative temperature coefficient (NTC) of piezoresistive temperature sensing elements.
