This work introduces a new type of water evaporation-driven nanogenerator (S-WEG) utilizing the natural mineral sepiolite, which capitalizes on its hierarchical nanoporous architecture and intrinsic hydrophilicity to harvest energy from ambient humidity through capillary-driven evaporation. The S-WEG, fabricated via a facile drop-coating drying method, demonstrates remarkable mechanical flexibility and sustained operational reliability. Our results demonstrate that by optimizing evaporation height and width, the S-WEG can generate a short-circuit current of ~0.6 μA and an open-circuit voltage of ~0.9 V. Through series and parallel configurations of multiple S-WEG units, the current and voltage outputs can be effectively amplified to power small-scale electronics.
这项工作介绍了一种利用天然矿物海泡石的新型水蒸发驱动纳米发电机（S-WEG），它利用其分级纳米多孔结构和固有亲水性，通过毛细管驱动蒸发从环境湿度中获取能量。通过简便的滴涂干燥法制造的S-WEG表现出卓越的机械柔韧性和持续的运行可靠性。我们的结果表明，通过优化蒸发高度和宽度，S-WEG可产生约0.6 μA的短路电流和约0.9 V的开路电压。通过多个S-WEG单元的串联和并联配置，电流和电压输出可有效放大，以为小型电子设备供电。
