论文摘要
压电材料由于机械变形和电场的固有耦合而具有广泛的感应和能量转导应用。最近的发现表明，压电复合材料的不对称或异质微观结构可以与称为电弹药耦合的电场型宏观动量搭配，从而引入了新的设计自由度。在这项工作中，通过采用均质化方案，通过在压电复合材料系统的微观结构设计空间上进行了高吞吐量探索电摩孔耦合的物理起源。这项研究表明了材料成分特性和几何布置如何影响电弹药耦合，并针对感兴趣的应用巧妙地量身定制。
Piezoelectric materials have wide sensing and energy transduction applications due to their inherent coupling of mechanical deformation and electric field. Recent discoveries have revealed that asymmetric or heterogeneous microstructures of piezoelectric composites can create an additional coupling of macroscopic momentum to an electric field termed electro-momentum coupling, introducing a new degree of design freedom. In this work, by employing the homogenization scheme, the physical origin of electro-momentum coupling is explored by a high throughput sweep over the microstructure design space of a piezoelectric composite system. This study shows how material constituent properties and geometrical arrangements can affect electro-momentum coupling and be smartly tailored for applications of interest.
