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.

Abstract: A surfactant-free cosmetic composition is disclosed. The composition is a stable water in silicone oil (W/S) formulation containing a silicone oil phase portion and an aqueous phase portion, wherein the silicone oil phase portion contains an emollient having a pyrrolidone carboxylic acid group, oil-absorbing powder and silicone oil, and the aqueous phase portion contains 50 wt.% or more of water based on the total weight of the surfactant-free cosmetic composition. The composition may further contain a high content of vitamin C or a vitamin C derivative and has improved long term storage stability.
