Infrared detection technology has been popularized in many fields. It has received attention from countries all over the world. As one of its core sensitive metamaterials, pyroelectric materials have become a hot spot in dielectric physics and materials research in recent years. As a typical ferroelectric material, sodium bismuth titanate-based ceramics have received extensive attention due to their high depolarization temperature and large pyroelectric coefficient. The research status of sodium bismuth titanate-based pyroelectric ceramics was summarized. The means to enhance pyroelectric effect in different components were summarized, and the properties were compared. It is found that lead-free ceramic materials with high depolarization temperature and high pyroelectric coefficient can be obtained by doping single-component acceptors. Finally, some existing problems are discussed.
