Which mechanism causes resonant frequency shift in piezoelectric crystals?

💡 Explanation

Lattice structural defect propagation causes a resonant frequency shift because the crystal's elasticity changes with introduced defects, therefore impedance changes. The resonating frequency shifts rather than other electrical or thermal property changes; defects alter material's mass loading.
