Which mechanism causes decreased piezoelectric output when a PZT ceramic package accumulates microcracks under cyclic stress?

💡 Explanation

Decreased piezoelectric output arises with decreased domain wall mobility because microcracks in the PZT ceramic lattice impede domain switching under stress. Therefore resulting in lower polarization, rather than other effects like increased energy storage, that result from different failure mechanisms.
