Abstract: A sensor for measuring a temperature change amount. The sensor includes a first composite material layer including a polymer having a volume changing according to a temperature change amount; an electrode layer provided on one side of the first composite material layer and capable of representing the temperature change amount as a resistance change amount; and a second composite material layer at least partially provided on the upper side of the first composite material layer and containing polydimethylsiloxane (PDMS) and at least one of carbon nanotubes (CNT), boron nitride nanotubes (BNNT), and graphene or containing a thermoplastic polyurethane (TPU) so that the temperature change occurring on one side thereof is transferred to the other side thereof.
