Droplet-based electricity generators have been widely studied due to their high efficiency in converting droplet potential energy into electricity and its simple structure. However, current research on droplet-based electricity generators is limited by high spatial footprint, material durability and low-energy-density, which prevents the realization of efficient cyclic output in integrating with diverse electronic components (e.g., integrated circuits, microsensors, microcontrollers). Achieving low-wear, recyclable, high-energy-density output in a single or integrated droplet-based power generation system remains a formidable challenge. Here we propose a closed-cycle droplet-based electricity generator (CC-DEG) that enables efficient conversion of the cyclic motion of droplets confined to the circular tube into electrical energy by stimulation with external mechanical forces. The CC-DEG demonstrates exceptional performance, with a peak open-circuit voltage of 661 V and a peak power density of 71.226 kW/m<sup>3</sup>. Parametric studies, including frequency, rotational speed, etc., proved the efficiency and stability of the CC-DEG. Furthermore, the CC-DEG can serve as a speed sensor for detecting real-time speed. This innovative design not only greatly minimizes water waste and space occupation, but also offers low-cost fabrication and ease of manufacturing, which provides an ideal strategy for integrating water-based generators into multifunctional sensors.</div></div>","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"141 ","pages":"Article 111100"},"PeriodicalIF":16.8,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
