Recent Progress on Barium Titanate‐Based Ferroelectrics for Sensor Applications

Abstract Sensors, functioning as primary conveyors of perceptual data, stand ready to illuminate the landscape of the intelligent era. Barium titanate, an exceedingly pivotal class of ferroelectric materials for sensor applications, has attracted considerable attention from both commercial and industrial sectors in recent years. Against this backdrop, this paper embarks on a comprehensive examination of sensors founded upon barium titanate across a spectrum of applications. Our investigation commences with a historical analysis of ferroelectric materials, with a specific emphasis on the developmental trajectory of barium titanate. Subsequently, an in‐depth exposition elucidates the attributes and manufacturing processes linked to barium titanate materials, providing readers with insight into the structural and manufacturing aspects of these materials. Ultimately, we introduce a diverse array of sensors tailored to distinct functions within a myriad of domains.
