Which risk increases when a piezoelectric sensor’s integrated capacitance is driven at resonance?

A)Amplified structural feedback oscillations occur
B)Spurious generation of Hall voltages
C)Localized crystallization gradients appear
D)Complete dielectric breakdown occurs

💡 Explanation

Significant structural oscillations are driven by resonance. The sensor will amplify its own vibrations through structural feedback because at resonance, energy transfer is most efficient via constructive interference, therefore amplified oscillation, rather than other electrical or material failures.
