压电聚合物广泛应用于传感器和执行器中。与陶瓷材料相比，它们具有机械灵活性和类似于水或空气的声阻抗的优势。它们的电、机电和机械性能可以通过分析其介电频谱中的压电共振来研究。除了能够揭示压电聚合物薄膜的高频行为外，这项技术从实用的角度来看也很有吸引力，因为只需一次扫描就可以测量几个重要的参数，这只需要许多实验室中常见的标准介电光谱设备。本文概述了压电谐振的理论基础，考察了其实验方面，并综述了近年来在压电聚合物领域中的应用。
Piezoelectric polymers are widely used in sensor and actuator applications. Compared to ceramic materials, they have the advantage of mechanical flexibility and an acoustic impedance similar to those of water or air. Their electrical, electromechanical and mechanical properties can be investigated by analyzing piezoelectric resonances in their dielectric spectrum. Apart from its ability to reveal the high-frequency behavior of piezoelectric polymer films, this technique is appealing from a practical point of view because several important parameters can be measured with a single scan that only requires standard dielectric spectroscopy equipment commonly found in many laboratories. This article outlines the theoretical foundations of piezoelectric resonance, examines the experimental aspects, and reviews recent applications in the field of piezoelectric polymers.
