压电陶瓷/聚合物复合材料，也称为压电复合材料，在过去的二十年中已经开发出用于军事和民用应用的机电换能器。近年来，这些换能器的发展趋势是向高工作频率发展，这就要求压电复合材料具有精细尺寸（< 200 μm陶瓷相尺寸）。这些细尺度的压电复合材料的加工方法进行了讨论。目前的能力，以及每种方法的优点和缺点，进行了比较。综述了医学成像的基本原理和空间尺度在复合材料性能中的重要性。几种加工方法证明了具有细尺度陶瓷相（< 50 μm）的复合材料，而其他方法已经显示出形成具有20 μm以下陶瓷尺度的复合材料的潜力。
Piezoelectric ceramic/polymer composites, also known as piezocomposites have been developed over the past two decades for electromechanical transducers to be used in both military and civilian applications. Recently, the thrust in these transducers is toward high operating frequencies, requiring fine-scale ( < 200- μm ceramic-phase dimension) piezocomposites. Methods for processing these fine-scale piezocomposites are discussed. Current capabilities, as well as strengths and weaknesses of each method, are compared. The fundamentals of medical imaging and the importance of spatial scale in composite performance are reviewed. Several processing methods demonstrated composites with fine-scale ceramic phases ( < 50 μm), and others have shown the potential to form composites with a ceramic scale of under 20 μm.
