PIEZOELECTRIC RESONANCE

Mechanical Oscillation of Quartz Crystal Under AC Drive
Drive Frequency (kHz) 1.00 kHz
Drive Amplitude (V) 1.0 V
Q Factor 50
—Mechanical Amplitude (μm)
—Phase Lag (°)
—Peak Amplitude (μm)
A piezoelectric crystal (e.g., quartz) converts electrical energy to mechanical vibration. At the resonant frequency f₀, impedance drops and amplitude peaks sharply. The Q factor determines the sharpness of resonance — high-Q crystals make ultra-stable oscillators in clocks and filters.
