Hydrogen, a clean-burning fuel, is of key importance to various industrial applications, including fuel cells and the aerospace and automotive industries. However, hydrogen gas is odorless, colorless, and highly flammable; thus, appropriate safety protocol implementation and monitoring are essential. Highly sensitive hydrogen-gas leak detection and surveillance systems are needed; additionally, the ability to monitor large areas (e.g., cities) via wireless networks is becoming increasingly important. In this report, we introduce a radio frequency identification (RFID)-based wireless smart-sensor system, composed of a Pt-decorated reduced graphene oxide (Pt_rGO)-immobilized RFID sensor tag and an RFID-reader antenna-connected network analyzer to detect hydrogen gas. The Pt_rGOs, produced using a simple chemical reduction process, were immobilized on an antenna pattern in the sensor tag through spin coating. The resulting Pt_rGO-based RFID sensor tag exhibited a high sensitivity to hydrogen gas at unprecedentedly low concentrations (1 ppm), with wireless communication between the sensor tag and RFID-reader antenna. The wireless sensor tag demonstrated flexibility and a long lifetime due to the strong immobilization of Pt_rGOs on the substrate and battery-independent operation during hydrogen sensing, respectively.

基于Pt /石墨烯固定射频识别标签的无线氢气智能传感器
氢是一种清洁燃烧的燃料，对包括燃料电池，航空航天和汽车工业在内的各种工业应用都至关重要。但是，氢气无味，无色且易燃。因此，适当的安全规程实施和监控至关重要。需要高度灵敏的氢气泄漏检测和监视系统；此外，有能力监控大面积（例如，市）通过无线网络变得越来越重要。在本报告中，我们介绍了一种基于射频识别（RFID）的无线智能传感器系统，该系统由固定有Pt的还原氧化石墨烯（Pt_rGO）固定的RFID传感器标签和与RFID阅读器天线相连的网络分析仪组成，用于检测氢气。使用简单的化学还原工艺生产的Pt_rGOs通过旋涂固定在传感器标签中的天线方向图上。所得的基于Pt_rGO的RFID传感器标签在前所未有的低浓度（1 ppm）下表现出对氢气的高灵敏度，并且在传感器标签和RFID读取器天线之间实现了无线通信。
