The loss of piezoelectric properties is called:

Explanation:
Piezoelectric properties come from aligned electric dipoles in a poled material. When that alignment is lost, the material’s ability to generate or respond to electric fields fades—that loss is depolarization. Depolarization can occur if the material is heated above its Curie temperature, exposed to strong alternating electric fields, or subjected to aging and mechanical stresses that disturb the polarization. The other terms don’t fit: demagnetization is about magnetic domains, degradation is too general, and demineralization refers to mineral loss, not polarization.
