Harvesting clean energy from moisture

Harvesting clean energy from moist air has been a promising solution for a sustainable future. However, developing a highly efficient, large-scale, integrated moisture-induced electricity generator is still challenging. In a recent Joule paper, Qu and co-workers reported fully printed planar moisture-induced electricity generator (MEG) arrays with high customizability and scalability via screen printing, demonstrating the potential of MEG as a compact power source that may pave the way for practical applications of MEG.
