Observational analysis establishes the impact of pore structure on density and permittivity in porous PZT ceramics, suggesting better pyroelectric performance via template method.
Compared with random, radial, and unidirectional, bidirectionally freeze-cast porous PZT builds aligned pore pathways that tune d T /d t , lower permittivity and density, and preserve the pyroelectric coefficient, yielding superior F i , F p , and J p .
