Nonetheless, the complex and ever-changing natural environment requires that the system not only complete a wide range of monitoring tasks but also provide remote and instantaneous wireless sensing capabilities. This work proposes a self-powered wireless environmental monitoring system based on a configurable Rotary Switch TENG (RS-TENG), which integrates deep learning algorithms and is capable of multi-parameter environmental monitoring. The RS-TENG can work with wind and record speed information; a capacitive strain sensor equipped on bridges and an inductive weight sensor plated around mountains are also considered monitoring nodes for multi-parameter monitoring in the natural environment. A resonant circuit and a tip-discharge structure allow the steady transmission of wireless signals that carry significant bridge component deformation and rockfall information to the user interface for decision-making. With deep learning algorithms, the system detects the deformation states of bridge components and rockfall warning signals and identifies defined levels. By adopting a shared wind cup, the RS-TENG allows the node to power electronic devices while enabling entirely automatic wireless wind monitoring. Furthermore, a user-friendly visualization interface is built for this environmental monitoring system, which allows users to assign monitoring tasks and get reasonable results. This work provides a paradigm for TENG technology applied in self-powered wireless environmental monitoring in complicated and particular natural environments.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"15 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142542069","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}
