X‐ray radiation is a leading cause of cancer, and thus a device that offers effective and real‐time radiation monitoring is of significant interest. The configuration design, fiber drawing, and device construction are introduced for a multimaterial fiber detector system that allows real‐time and remote X‐ray monitoring. A fiber detector embedded with metal–semiconductor–insulator ladder‐like configuration is designed and successfully constructed on the basis of Plateau–Rayleigh instability. The multimaterial design affords the detector robust radiation‐harvesting ability, enabling the collection of up to ≈88.13% of total X‐ray energy. The unique ladder‐like configuration allows the efficient generation and collection of free charges. Moreover, the detector exhibits excellent mechanical flexibility and can be woven into a complex configuration and even wearable fabrics. Finally, the application of the micro‐detector in real‐time wireless X‐ray monitoring is demonstrated. This research not only presents a flexible radiation detection strategy for various ionizing radiation types, such as X‐ray, gamma ray, and neutrons radiation, but also has potential uses in remote radiation monitoring in case a conventional rigid device is inapplicable.

用于实时和远程X射线监控的多材料光纤检测器

X射线辐射是导致癌症的主要原因，因此，提供有效且实时的辐射监测的设备非常重要。介绍了用于多材料光纤检测器系统的配置设计，光纤拉伸和设备构造，该系统可进行实时和远程X射线监视。在高原-瑞利不稳定性的基础上，设计并成功构建了嵌入金属-半导体-绝缘体阶梯状结构的光纤检测器。多种材料的设计为探测器提供了强大的辐射收集能力，能够收集高达总X射线能量的约88.13％。独特的梯形配置可有效生成和收取免费费用。此外，该探测器具有出色的机械柔韧性，可以织成复杂的结构，甚至可穿戴的织物。最后，演示了微探测器在实时无线X射线监测中的应用。这项研究不仅提出了针对各种电离辐射类型（例如X射线，γ射线和中子辐射）的灵活辐射检测策略，而且在常规刚性设备不适用的情况下，还可以用于远程辐射监测。
