Ferroelectric materials have attracted interest for over a hundred years as a result of their spontaneous polarization and a polarization orientation that can be reversed by the application of an external electric field. In addition, the degree of polarization can be affected by external stimuli such as vibrations, stress, heat, and light. These properties enable ferroelectric materials to be used to fabricate nanogenerators, which are devices used in energy scavenging applications and provide an opportunity to obtain electrical energy from a variety of external stimuli. This review discusses the development of ferroelectric-based nanogenerators for scavenging mechanical, thermal, and solar energies through the piezoelectric effect, pyroelectric effect, and photovoltaic effect, respectively. The mechanisms of the effects and the pathways to optimize the output performance of the nanogenerators are analyzed in detail. Recent developments in energy harvesting using ferroelectric materials are discussed with the objective to motivate attention and efforts in this growing field.

使用铁电材料清除能源

一百多年来，铁电材料因其自发极化和可以通过施加外部电场逆转的极化方向而引起了人们的兴趣。此外，极化程度会受到外部刺激的影响，例如振动、压力、热量和光。这些特性使铁电材料能够用于制造纳米发电机，纳米发电机是用于能量清除应用的设备，并提供了从各种外部刺激中获取电能的机会。本综述讨论了分别通过压电效应、热电效应和光伏效应清除机械能、热能和太阳能的铁电纳米发电机的发展。详细分析了影响的机制和优化纳米发电机输出性能的途径。讨论了使用铁电材料进行能量收集的最新进展，目的是在这个不断发展的领域激发人们的注意力和努力。
