High-Power Characterization of d32 -Mode Mn:PIN-PMN-PT Piezoelectric Single Crystals at Different Temperatures
2021 IEEE International Ultrasonics Symposium (IUS)(2021)
摘要
Mn:PIN-PMN-PT plates: [011]-poled (mm2 symmetry, d
32
-mode) were characterized at high-power excitation levels and at different temperatures. A bespoke high-power measurement system was utilized to acquire the electrical impedance at resonance. Results have shown that the resonant frequency/anti-resonant frequency downshifts with increasing driving voltage and temperature.
