In this article, we report on an energy-harvesting device using a hybrid flexible polymer nanocomposite as a tribo–piezo layer for energy generation. Piezoelectric nano zinc oxide (ZnO) and exfoliated graphene oxide (EGO) are used with a piezoelectric poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) polymer matrix to prepare the energy-generating layer. An enhancement of the β phase in P(VDF-TrFE) is achieved by the method used for film preparation and the addition of ceramic nanoparticles to the matrix. The devices are tested under manual and mechanical tapping to generate electrical energy which is stored in a commercial capacitor. The fabricated hybrid polymer nanocomposite device generated 2.27 V (manual tapping), 11.6 V (qualitative analysis), and 28.3 V (quantitative analysis). Knock sensing action of the prototype device is also demonstrated. The hybrid polymer nanocomposite device with excellent touch sensitivity that is lightweight with distinguished energy-generating efficiency can be used in the self-powered energy-harvesting electronic devices of tomorrow.

聚（偏二氟乙烯-三氟乙烯）-ZnO纳米颗粒复合材料在柔性聚二甲基硅氧烷基底上的能量收集

在本文中，我们报告了一种使用杂化柔性聚合物纳米复合材料作为摩擦压电层来产生能量的能量收集装置。压电纳米氧化锌（ZnO）和片状氧化石墨烯（EGO）与压电聚偏二氟乙烯-三氟乙烯（P（VDF-TrFE））聚合物基质一起使用，以制备能量产生层。P（VDF-TrFE）中β相的增强是通过用于薄膜制备的方法以及将陶瓷纳米颗粒添加到基质中来实现的。在手动和机械攻丝下对设备进行测试，以产生电能，该电能存储在商用电容器中。制成的杂化聚合物纳米复合器件产生2.27 V（手动攻丝），11.6 V（定性分析）和28.3 V（定量分析）。还演示了原型设备的爆震感测功能。轻巧且具有出色的能量产生效率的具有出色的触摸灵敏度的混合聚合物纳米复合材料器件可用于未来的自供电能量收集电子设备。
