Abstract In this work, we have studied the electrical response of a sandwiched piezoelectric transducer as a function of the height of a water column used as an acoustical load. This study covers investigations about the behavior of resonance, anti-resonance, electromechanical coupling factor, motional resistance, and mechanical loss. The results show that the performance of the transducer is dependent on the acoustic load. The heights where the conversion is maximum coincides with the minimum value for the mechanical loss. These results can be used for the design of the hardware in ultrasonic systems that include dynamical resonance tracking and control of power supply.

声载荷对压电换能器性能影响的实验研究

摘要 在这项工作中，我们研究了夹层压电换能器的电响应与用作声负载的水柱高度的函数关系。这项研究涵盖了对共振行为、反共振、机电耦合因子、运动阻力和机械损耗的研究。结果表明，换能器的性能取决于声学负载。转换最大的高度与机械损失的最小值一致。这些结果可用于包括动态共振跟踪和电源控制在内的超声波系统中的硬件设计。
