Multimaterial Fiber Detector for Real-Time and Remote X-Ray Monitoring

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.
