← ScienceWhich outcome occurs when exceeding shock loading of piezoelectric crystal?
A)Depolarization due to domain wall motion✓
B)Increased sensitivity above Curie temperature
C)Enhanced charge collection across interfaces
D)Improved voltage coefficient below resonance
💡 Explanation
Exceeding crystal's poling electric field causes depolarization; domain wall motion repositions atomic dipoles because mechanical stress exceeds electrostatic restoring force. Therefore, depolarization results in reduced electrical output rather than altered sensor characteristics under normal operating conditions.
