PMN-PT transducer: high stress measurements at resonance

High power piezoelectric devices are driven under high electric signal. To characterize the material in conditions close to their use in high acoustic power emission, we need to reach high strain or high strain velocity. This can be achieved only at resonance where the mechanical Qm factor amplifies...
