Ultrahigh piezoelectric performance demonstrated in ceramic materials

Phys Dot Org 18 May 2022

"There are many mechanisms that limit the magnitude of piezoelectricity in polycrystalline ceramic materials ... What factors control the magnitude of piezoelectric constant? The piezoelectric constant is the charge generated by a unit of applied force, picocoulomb per Newton, which in turn is dependent on effects occurring at atomic to mesoscale.
