However, the development of flexible sensors that demonstrate both high sensitivity and reliability while being suitable for integration into actuated parts remains a challenge. In this study, we developed a wing-shaped sensor composed of a hollow fiber polymer structure, into which liquid metal was injected as a flexible conductive material and encapsulated with Ecoflex, which overall presents a cantilever beam structure on both sides. The hollow fiber acts as a natural insulator for the liquid metal coils, while their inner and outer diameters are only 190 and 290 μm, respectively. When both ends of the sensor are deformed by external action, the cantilever beams on both sides will be displaced relative to each other like wings, resulting in a corresponding change in the spatial position of the liquid metal coil, which in turn generates a change in the inductance signal. By leveraging this phenomenon, the wing-type sensor can detect minute displacements at both ends with an accuracy of 5% of their thickness while maintaining excellent stability over 100 cycle tests. This sensor was also able to measure wind speeds in a specific range of 2–10 m/s, with trends that conformed well to both theoretical foundations and simulation results. Further, we have demonstrated several application scenarios for this sensor using this superposition sensing mechanism.

Memristive properties were investigated following the confirmation of MoO<sub><i>x</i></sub> formation on the MoS<sub>2</sub> surface via optical and electrical characterization. These properties included multiresistive state behavior dependent on the voltage sweep range, low resistance state current level twice that of the high resistance state, and robust stability (∼5000 s). Consequently, the potential for developing a two-dimensional, oxide-based memristor is presented based on an analysis of the voltage–current relationship and proposed switching mechanism of the MoS<sub>2</sub>–MoO<sub><i>x</i></sub> junction.</p>","PeriodicalId":3,"journal":{"name":"ACS Applied Electronic Materials","volume":"7 9","pages":"3737–3743 3737–3743"},"PeriodicalIF":4.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143934010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
