Water and electricity scarcity are two global challenges, especially in arid and remote areas. Harnessing ubiquitous moisture and sunlight for water and power generation is a sustainable route to address these challenges. Herein, we report a moisture-induced energy harvesting strategy to realize efficient sorption-based atmospheric water harvesting (SAWH) and 24-hour thermoelectric power generation (TEPG) by synergistically utilizing moisture-induced sorption/desorption heats of SAWH, solar energy in the daytime and radiative cooling in the nighttime. Notably, the synergistic effects significantly improve all-day thermoelectric power density (~346%) and accelerate atmospheric water harvesting compared with conventional designs. We further demonstrate moisture-induced energy harvesting for a hybrid SAWH-TEPG device, exhibiting high water production of 750 g m⁻², together with impressive thermoelectric power density up to 685 mW m⁻² in the daytime and 21 mW m⁻² in the nighttime. Our work provides a promising approach to realizing sustainable water production and power generation at anytime and anywhere.

水和电短缺是两个全球性挑战，特别是在干旱和偏远地区。利用无处不在的水分和阳光进行水和发电是应对这些挑战的可持续途径。在此，我们报告了一种湿气诱导的能量收集策略，通过协同利用湿气诱导的SAWH吸附/解吸热、太阳能，实现高效的基于吸附的大气水收集（SAWH）和24小时热电发电（TEPG）。白天和夜间辐射冷却。值得注意的是，与传统设计相比，协同效应显着提高了全天热电功率密度（~346%）并加速了大气水的收集。我们进一步演示了混合 SAWH-TEPG 装置的湿气诱导能量收集，该装置表现出 750 gm ^-2的高产水量，以及令人印象深刻的热电功率密度，白天高达 685 mW m ^-2 ，白天高达 21 mW m ^-2夜间。我们的工作为随时随地实现可持续水生产和发电提供了一种有前景的方法。
