Visible light is an important energy source for all living organisms on Earth. Given the importance of visible light, visible light sensors have attracted widespread interest from scientists. With the rapid development of wearable devices, the sensors used in them need to be flexible, stretchable, and lightweight. Herein, an intelligent electrolyte based on spiropyran (SP) that responds to visible light is developed. The reversible change rate in the electrical resistance of an SP/FeCl·6HO methyl cyanide (MeCN) aqueous solution under visible light irradiation is as high as 19.26%. Additionally, flexible and conductive fibrous visible light sensors with a core-sheath structure are prepared using an SP/FeCl·6HO MeCN aqueous solution and silicon rubber hollow fibers as the core and outer layers, respectively. These fibrous visible light sensors are then woven into fabrics with multiple functions, such as sensing and locating visible light, reversible photochromism, and thermal management. The fibrous visible light sensors and fabrics prepared in this study have broad development prospects and application potential in the fields of fashion, smart textiles, flexible conductive fibers, flexible fibrous sensors, electronic skins, and wearable devices.
可见光是地球上所有生物的重要能量来源。鉴于可见光的重要性，可见光传感器已引起科学家们的广泛关注。随着可穿戴设备的迅速发展，其中使用的传感器需要具备柔性、可拉伸和轻质的特点。在此，开发了一种基于螺吡喃（SP）的智能电解质，其对可见光有响应。在可见光照射下，SP/FeCl·6H₂O乙腈（MeCN）水溶液的电阻可逆变化率高达19.26%。此外，分别以SP/FeCl·6H₂O MeCN水溶液和硅橡胶中空纤维为芯层和外层，制备了具有核壳结构的柔性导电纤维可见光传感器。然后将这些纤维可见光传感器编织成具有多种功能的织物，如传感和定位可见光、可逆光致变色以及热管理。本研究制备的纤维可见光传感器和织物在时尚、智能纺织品、柔性导电纤维、柔性纤维传感器、电子皮肤和可穿戴设备等领域具有广阔的发展前景和应用潜力。
