Which effect results when compressive stress exceeds limits within piezoelectric crystal stacks?

A)Charge generation ceases completely
B)Acoustic emission rate accelerates
C)Polarization domains randomly reorient
D)Curie temperature decreases to zero

💡 Explanation

Polarization domain randomization occurs because the applied stress overcomes the crystal's coercive field. Increasing compression leads to loss of piezoelectric function, therefore polarization changes rather than complete failure, due to the statistical nature of domain reversal.
