压电纳米发电机是一种将机械能转化为电能的很有前途的发电装置。柔性和可伸缩的压电能量采集器可以检测心跳、脚步、环境噪声和气流等低频信号，具有广阔的应用前景。因此，由于其毒性较小，开发无铅压电纳米发电机是必要的。一维氧化锌(纳米线和纳米棒)和钙钛矿基材料(BaTiO_3和BiFeO_3)因其优异的压电性能和环境友好性而被广泛研究用于压电纳米发电机。到目前为止，各种电极、衬底、纳米结构和聚合物都被用来提高压电器件的效率。在这篇综述中，我们讨论了最新的成就，可伸缩的压电纳米线，纳米复合纳米发电机，以及无铅柔性能量收集装置的未来可能性。
Piezoelectric nanogenerator has emerged as a promising power generation device that converts mechanical energy into electrical energy. Flexible and stretchable piezoelectric energy harvesters can detect low frequencies like heartbeat, footsteps, ambient noise, and airflow, which is promising for further application. Thus, the development of a lead-free piezoelectric nanogenerator is required owing to its less toxic nature. One-dimensional ZnO (nanowire and nanorods) and perovskite-based materials (BaTiO3and BiFeO3) have been widely investigated for piezoelectric nanogenerators because of their excellent piezoelectric properties and environmental friendliness. Hitherto, various electrodes, substrates, nanostructures, and polymers have been utilized to improve the efficiency of piezoelectric devices. In this review, we discuss the state-of-the-art achievements, stretchable piezoelectric nanowire, nanocomposite nanogenerators, and future possibilities of lead-free flexible energy harvesting devices.
