Water utilization is accompanied with the development of human beings, whereas gaseous moisture is usually regarded as an underexploited resource. The advances of highly efficient hygroscopic materials endow atmospheric water harvesting as an intriguing solution to convert moisture into clean water. The discovery of hygroelectricity, which refers to the charge buildup at a material surface dependent on humidity, and the following moisture-enabled electric generation (MEG) realizes energy conversion and directly outputs electricity. Much progress has been made since then to optimize MEG performance, pushing forward the applications of MEG into a practical level. Herein, the evolvement and development of MEG are systematically summarized in a chronological order. The optimization strategies of MEG are discussed and comprehensively evaluated. Then, the latest applications of MEG are presented, including high-performance powering units and self-powered devices. In the end, a perspective on the future development of MEG is given for inspiring more researchers into this promising area.
水的利用伴随着人类的发展，而气态水分通常被视为一种未被充分开发的资源。高效吸湿材料的进展使大气集水成为一种将水分转化为清洁水的有趣解决方案。湿电效应的发现，即材料表面电荷积累取决于湿度，以及随后的湿气发电（MEG）实现了能量转换并直接输出电力。从那时起，在优化MEG性能方面取得了很大进展，推动了MEG的应用进入实际水平。在此，按时间顺序系统地总结了MEG的演变和发展。讨论并全面评估了MEG的优化策略。然后，介绍了MEG的最新应用，包括高性能供电单元和自供电设备。最后，对MEG的未来发展给出了展望，以激励更多研究人员进入这个有前途的领域。
