Advanced acoustic levitation devices featuring flexible, lightweight, wide bandwidth, and film-like transducers based on ferroelectrets are designed and fabricated for sophisticated manipulation of particles in a simple way. Owing to the unique properties of ferroelectret films, such as high piezoelectric activity, very small acoustic impedance, a relatively large damping ratio, flexibility, a large area, and small density, the levitator reported features a wider bandwidth compared to ceramic-based levitators. The transportation of levitated particles is achieved by deformation of the film transducer, which represents a different and promising concept for this task.

基于铁电驻极体的柔性换能器：一种用于悬浮和操纵粒子的策略。

设计和制造了具有灵活，轻便，宽带宽和基于铁电驻极体的薄膜状换能器的先进声悬浮设备，可通过简单的方式对粒子进行复杂的处理。由于铁电驻极体薄膜的独特特性，例如高压电活性，非常小的声阻抗，相对较大的阻尼比，柔韧性，大面积和小密度，据报道该悬浮剂比基于陶瓷的悬浮剂具有更宽的带宽。悬浮粒子的运输是通过薄膜换能器的变形来实现的，这代表了这一任务的一个不同而有希望的概念。
