In sensors based on the anomalous Hall effect, a large anomalous Hall angle can improve the sensitivity of magnetic field detection. However, the modulation of this angle is challenging, and magnetic materials typically have low angles of 0.1°–3°. Here we report the modulation of θA in the magnetic Weyl semimetal Co3Sn2S2. We show that the anomalous Hall angle parameter tanθA can be formulated as a function of the product of electrical resistivity and anomalous Hall conductivity. We use this scheme to demonstrate the modulation of tanθA up to a magnitude of 0.46, corresponding to an angle of around 25°. We further fabricate anomalous Hall devices using Fe-doped Co3Sn2S2 single-crystalline nanoflakes and demonstrate a Hall sensitivity of 7,028 ± 341 μΩ cm T–1 and a magnetic field detectability of 23.5 ± 1.7 nT Hz–0.5 at 1 Hz.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"32 1","pages":""},"PeriodicalIF":34.3,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, electrodermal activity has not been considered useful for physical activity monitoring, where large sweat volumes are generated, resulting in the accumulation of sweat at the skin–electrode interface and, thus, preventing further dynamic response to sweating events. Here we show that electrodermal activity can be used as a proxy for sweat loss measurement under both low and high physical activity levels. We use wearable sweat sensors that consist of water-permeable electrodes and microfluidic-based sweat analysers, and show that skin conductance is proportional to the instantaneous sweat loss. We demonstrate that sweat loss during exercise can be estimated by integrating skin conductance over time, which can be applied to assess the body hydration status of exercisers. From multisite measurements of skin conductance, we show that the wrist, forearm and upper arm are reflective of physical activity levels, whereas the finger is indicative of mental activity. Simultaneous measurement of two different sites selectively decouples mental and physical activities.","PeriodicalId":19064,"journal":{"name":"Nature Electronics","volume":"72 1","pages":""},"PeriodicalIF":34.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
