The extensive exposure of the human epidermis to solar radiation creates a health risk that results in skin cancer. Commercial sunscreens offer sufficient protection from ultraviolet (UV) radiation; however, the ability to determine UV exposure limits can provide informed decisions about the dose of sunscreen required and the frequency of re‐application. Here, a wide range of wearable devices that colorimetrically report on UV exposure are developed. Under UV radiation, UV‐sensitive dyes change their color from 280 to 400 nm in the visible spectrum. By correlating the current color value and the UV dose, the amount of sun exposure is determined with an accuracy of 95%. A smartphone camera algorithm is coded to automatically perform the color analysis of these dyes. The UV‐sensitive dyes are incorporated in wearable devices, skin patches, textiles, contact lenses, and tattoo inks. The developed wearable devices will ensure monitoring UV radiation to rationally manage the user's behavior in order to prevent harmful sun exposure.

比色法监测紫外线的紫外线敏感型可穿戴设备

人的表皮广泛暴露于太阳辐射下会产生健康风险，导致皮肤癌。商业防晒霜可提供足够的紫外线防护。但是，确定紫外线暴露极限的能力可以提供有关所需防晒剂量和重新使用频率的明智决定。在此，开发了多种可比色报告紫外线暴露的可穿戴设备。在紫外线辐射下，对紫外线敏感的染料在可见光谱中的颜色从280纳米更改为400纳米。通过将当前颜色值与UV剂量相关联，可以以95％的精度确定日照量。对智能手机相机算法进行编码，以自动执行这些染料的颜色分析。对紫外线敏感的染料可用于可穿戴设备，皮肤补丁，纺织品，隐形眼镜和纹身墨水。开发的可穿戴设备将确保监控紫外线辐射，从而合理管理用户的行为，以防止有害的日光曝晒。
