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 gradient 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
