设计并制备了钛酸钡（BTO）/环氧树脂复合材料，研究了极化条件对其压电性能的影响，并获得了其非稳态能量收集电位。极化条件试验研究了极化条件对BTO/环氧复合材料压电性的影响。在不同条件下对试样进行电晕极化，测量了它们的压电系数d（33）。利用扫描电子显微镜（SEM）研究了压电颗粒在基体中的分布，并利用X射线衍射（XRD）研究了压电颗粒的微观结构。然后进行了风收集试验，并测量了非定常气流下复合材料片的输出电压。这项研究为开发灵活的能量收集设备开辟了道路。
The objective of this paper is to design and fabricate barium titanate (BTO)/epoxy composites, investigate the effect of poling conditions on their piezoelectric properties, and obtain their unsteady energy harvesting potential. The poling condition test deals with the effect of the poling conditions on the piezoelectricity of BTO/epoxy composites. The specimens are polarized by corona poling under different conditions, and their piezoelectric coefficient d(33) is measured. The distribution of the piezoelectric particles in the matrix is studied using scanning electron microscopy (SEM), and the microstructure of the particle is investigated using X-ray diffraction (XRD). A wind harvesting test is then performed, and the output voltage is measured for the composite sheets under unsteady air flow. This study opens the way for the development of flexible energy harvesting devices.
