摘要: This study presents the fabrication of triple-layer piezoelectric vibrator and analyzes its electrical impedance. The characterization impedance equivalent circuit element in thickness vibration mode is discussed. dielectric, elastic, electro mechanical coupling constants (kt) samples were evaluated from experimental data. A simple but practical expressed using only parameters vibrator, was explored. Analysis based on this can provide a good understanding behavior vibrators as function frequency mode. will turn aid design analysis transducers.
