Abstract: Calcium and lanthanum modified lead titanate (PCLT) powder was prepared by a sol-gel process followed by annealing at 850 °C. The PCLT powder was dispersed in vinylidene fluoride-trifluoroethylene copolymer [P(VDF-TrFE)] to form a composite containing 12 vol.% of ceramic powder. A film of thickness 12 μm was prepared by spin-coating four layers of the composite on a glass substrate. The film was poled and then removed from the substrate. It was then bonded to a silicon chip with readout electronic circuitry to form an 8×1 integrated linear pyroelectric array. The voltage responsivity, voltage noise, and specific detectivity of the sensors in the array were measured as functions of frequency and found to agree well with the values calculated from a one-dimensional heat diffusion model.
