我们已经开发并展示了一种高度灵活的P（VDF-TrFE）薄膜为基础的能量收集装置的PDMS基板上，避免任何复杂的复合材料和图案化的结构。的P（VDF-TrFE）膜的结构和电性能进行了研究，使用多种表征技术和7 μ m厚的优化膜用于能量收集应用。具有Ti/Ni金属触点的装置由提供1.75g的加速度和从5到30 Hz变化的频率的振动器驱动。使用振动器测试最终制造的装置的能量收集性能，并且产生4.4V的最大输出电容器电压，其在充电几分钟后成功地为一组27个LED供电。
We have developed and demonstrated a highly flexible P(VDF-TrFE) film-based energy harvesting device on a PDMS substrate, avoiding any complex composites and patterned structures. The structural and electrical properties of the P(VDF-TrFE) film was investigated using multiple characterization techniques and an optimized film of 7 mu m thickness was used for the energy harvesting application. The device, with Ti/Ni metal contacts, was driven by a shaker providing an acceleration of 1.75 g, and frequencies varying from 5 to 30 Hz. The energy harvesting performance of the final fabricated device was tested using the shaker, and resulted in a maximum output capacitor voltage of 4.4 V, which successfully powered a set of 27 LEDs after several minutes of charging.
