UVR可根据波长分为UVA、UVB和UVC。要监测不同UV辐射的影响，就需要低成本的光谱选择性UV传感器。但目前的传感器由于造价高、制造工序复杂，很难实现大规模部署。

澳大利亚皇家理工大学的Vipul Bansal和同事设计出了一种具有光谱选择性的高灵敏度UV传感器的制造方法。他们的设计秘诀在于创造出了一种基于多金属氧酸盐的隐形墨水。这种墨水具有光谱选择性UV感应的特殊性能，与低成本的现成部件（如滤纸、透明膜或钢笔）结合后，就能制造出一种纸基的低成本可穿戴UV传感器。

作者通过一个定制的纸基笑脸式UV传感器展示了这项新技术的适用性，该传感器可以针对6种不同皮肤类型对每种UVR的最大允许照射量阈值进行实时照射剂量监测。这一结果表明，光谱选择性UV传感器或有潜力投入大规模生产，并对特定皮肤类型进行定制。
摘要：Spectrallyselective monitoring of ultraviolet radiations (UVR) is of paramount importance across diverse fields, including effective monitoring of excessive solar exposure. Current UV sensors cannot differentiate between UVA, B, and C, each of which has a remarkably different impact on human health. Here we show spectrally selective colorimetric monitoring of UVR by developing a photoelectrochromic ink that consists of a multi-redox polyoxometalate and an e donor. We combine this ink with simple components such as filter paper and transparency sheets to fabricate low-cost sensors that provide naked-eye monitoring of UVR, even at low doses typically encountered during solar exposure. Importantly, the diverse UV tolerance of different skin colors demands personalized sensors. In this spirit, we demonstrate the customized design of robust real-time solar UV dosimeters to meet the specific need of different skin phototypes. These spectrallyselective UV sensors offer remarkable potential in managing the impact of UVR in our day-to-day life.
