Abstract

Photonic time-temperature sensor consisting of an embossed interpenetrating network of a cholesteric liquid crystalline polymers and a secondary polymer. Preferably in which the secondary polymer is orthogonal and is not covalently attached to the interpenetrating network, but physically interpenetrated therein. For use as food sensor for checking freshness of the food.
