Abstract With the depletion of the conventional energy sources, measures are being taken to create an alternate energy sources for the future. Energy harvesting from different sources are one of the better steps taken in this direction. Mechanical energy harvesting from the waste mechanical source is gaining profound investigation. Here, a nanohybrid of poly(vinylidene fluoride) and lead zirconia titanate (PZT) is prepared through solution route for energy harvesting applications. PZT is synthesized using solid state route and its concentration was varied in the nanohybrid to get the best properties from the hybrid. Structural and morphological aspects of the nanohybrid have been explored for their suitable application. Device has been fabricated using the nanohybrid to convert the waste mechanical energy from various human motions to the useful electrical energy. The device is able to generate a maximum output voltage of 55 V and a power density of 36 μ Wcm−2. The device is able to produce voltage output from different human motions such as finger tapping, feet tapping and bending. The mechanism of charge conversion is also discussed which explains the generation of such a high electrical output from waste mechanical source.

用于能量收集应用的基于 PVDF-PZT 纳米杂化物的纳米发电机

摘要 随着传统能源的枯竭，正在采取措施为未来创造替代能源。从不同来源收集能量是朝这个方向采取的更好的步骤之一。从废弃机械源中收集机械能正在得到深入的研究。在这里，聚偏二氟乙烯和氧化锆钛酸铅 (PZT) 的纳米混合物通过溶液途径制备，用于能量收集应用。PZT 是使用固态途径合成的，其浓度在纳米杂化物中变化，以从杂化物中获得最佳性能。已经探索了纳米杂化物的结构和形态方面的合适应用。使用纳米杂化物制造的装置将来自各种人体运动的废弃机械能转化为有用的电能。该器件能够产生 55 V 的最大输出电压和 36 μ Wcm-2 的功率密度。该设备能够从不同的人体动作（例如手指敲击、脚敲击和弯曲）产生电压输出。还讨论了电荷转换机制，这解释了从废弃机械源产生如此高的电输出。
