摘要

Recent years, due to the problems of energy crisis and environment pollution, new technologies for harvesting clean energy from environment have attracted more and more attentions such as solar cells [1], thermoelectric devices [2], mechanical generators [3].However, all these devices have to work in a specific environment, which greatly limits the sustained energy harvesting.Because ambient humidity exits anytime and anywhere in the atmosphere, developing humidity-based technology could provide a potential solution for the sustained energy harvesting.In one strategy, the moisture gradient near the water source can drive microfluidic or nanofluidic water transport in thin films to induce charge transport for electrical output [4,5].This approach is difficult to realize and restricted to environment with water source.
