Impedance analysis for characterizing the influence of hydrostatic pressure on piezoelectric quartz crystal sensors

Résumé

The effect of hydrostatic pressure on the electrical behavior of quartz crystal resonators vibrating in the megahertz range is investigated by impedance analysis. The responses in frequency and dissipation of five AT-cut polished quartz crystals immersed in helium gas are analyzed and compared from conductance spectra around the resonance on several overtones. A model is then proposed to correlate the variations in frequency and dissipation with pressure and to explain the particular behavior observed on the fundamental harmonic mode.
