Abstract:
The structural and pyroelectric properties of partially Ca‐substituted BaTiO 3 , Ba 1− x Ca x TiO 3 (0 ≤ x ≤ 0.2), are investigated. Partial Ca‐substitution in BaTiO 3 introduced tetragonal distortion in the TiO 6 octahedrons and increased the displacement, Δ d , of a Ti 4+ cation from the center of an octahedron. This increase in Δ d led to enhancement of remanent polarization and pyroelectric voltage, V p . The pyroelectric energy storage behavior is demonstrated for the partially Ca‐substituted BaTiO 3 . For the Ba 0.9 Ca 0.1 TiO 3 sample which exhibited the highest V p , the stored energy in an output capacitor was proven to be sufficient to operate micropower Internet of Things devices.
