Abstract: Moisture-enabled electricity generation (MEG), an emerging energy-harvesting technology, has attracted significant attention in recent years. Owing to the ubiquitous presence of water vapor and the pollution-free nature of the power generation process, MEG technology demonstrates strong adaptability, that is, it is not limited by natural conditions such as season, region and environment. This paper presents a comprehensive review of the evolution of MEG technology. It discusses the interaction mechanism between moisture and power generation materials, primarily focusing on ion diffusion and streaming potential. It also provides a detailed analysis of the types, characteristics, advantages and disadvantages of new carbon-based hygroscopic layer materials. Furthermore, it describes the development of moisture power generation technology in the latest application fields.

Key words: Water vapor, Hygroscopic layer, Electrode, Moisture power generation
