Pyroelectric materials produce electric charge with the application of temperature changes.Thermal imaging has been used for military night vision, target acquisition, and missile guidance where Pyroelectric materials are used as Infrared detectors. Triglycine sulfate (TGS), polyvinyldifluoride (PVDF), strontium barium niobate (SBN), lithium tantalate (LT), and lead zirconate titantate (PZT) are some of the pyroelectric materials.
