Abstract : In the patent a polymer pyroelectric detector is made by selecting a film of polymeric material which has dipoles in its molecular structure. The film is treated so that the dipoles have a net orientation and the upper and lower surfaces of the film are coated with thin films of conductive material to act as electrodes. Detectors made from polyvinyl fluoride or polyvinylidene fluoride are sensitive to a wide range of electromagnetic radiation, especially radiation in the IR region.
