Recent days, considerable research efforts have been emphasized on the development of lightweight, portable, shock resistance, and flexible wearable devices that are powered by harvesting energy from abundant mechanical forces or vibrational energy. In this paper, we report piezoelectric nanogenerator (PNG) based on poly (vinylidene fluoride) (PVDF)/Zirconium oxide (ZrO₂)/Zinc oxide (ZnO) nanocomposite. The addition of nanofillers significantly affects the structural property of PVDF, and their addition helps in the improvement of the piezoelectric property. The PNGs are fabricated and tested under various stress conditions (at different loads, tapping and walking). The hybrid PVDF/5% ZrO₂/5% ZnO nanogenerator showed a maximum peak to peak voltage (Vpp) of 3.2 V, which is nearly eight times more than pristine PVDF nanogenerator. A prototype of shoe pad nanogenerator is demonstrated as an application.

最近，大量的研究工作都集中在轻量、便携、抗震和灵活的可穿戴设备的开发上，这些设备通过从丰富的机械力或振动能量中收集能量来提供动力。在本文中，我们报告了基于聚偏二氟乙烯 (PVDF)/氧化锆 (ZrO ₂ )/氧化锌 (ZnO) 纳米复合材料的压电纳米发电机 (PNG) 。纳米填料的加入显着影响了 PVDF 的结构性能，它们的加入有助于提高压电性能。PNG 是在各种应力​​条件下（不同负载、轻敲和行走）制造和测试的。混合 PVDF/5% ZrO ₂/5% ZnO 纳米发电机的最大峰峰值电压 (Vpp) 为 3.2 V，几乎是原始 PVDF 纳米发电机的八倍。鞋垫纳米发电机的原型作为应用程序进行了演示。
