    The film is an active film that consists of two PET (polyethylene terephthalate) sheets. These sheets are coated with   an electric conductive substance on one side, which ensures a constant and super-fast conduction of electricity. A   core is placed between the sheets and this consists of a sponge-like structure that is filled with liquid crystals. The   core is made from a polymer network which incorporates the liquid crystals.
