Composite Piezoelectric Oscillator

The crystal oscillator circuit sustains oscillation by taking a voltage signal from the quartz transducer, amplifying it, and feeding it back to the resonator. The rate of expansion and contraction of the quartz is the resonant frequency, and is determined by the cut and size of the crystal

Internal friction and modulus are useful probe to examine defects, microstructure and phase transitions as well as important parameters to monitor mechanical behavior. This study focuses a new piezoelectric composite oscillator method for modulus and internal friction measurement. The technique is appropriate to the evaluation of small-size ceramics test piece with 1-3mm thickness, 2-4mm wide and 10-40mm length. This technique can be applied to the measurement at elevated temperatures up to 800°C under direct heat environment without buffer materials.
