1. A sensor for measuring a temperature change amount of a cosmetic material, comprising:
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 a portion of which is provided on the first composite material layer, containing carbon nanotube (CNT), boron nitride nanotube (BNNT), graphene, and polydimethylsiloxane (PDMS) to transfer the temperature change occurring on one side to the other side,
wherein the second composite material layer has a thickness of 1 μm to 30 μm, and
wherein the cosmetic material is applied to the second composite material layer.
