论文摘要
环境腐蚀性由空气中的气态污染物以及温度和相对湿度的存在来控制室内应用。它的确定是一项具有挑战性的任务，需要监测少量纳米范围内所选金属的厚度减小。目前的工作旨在开发用于此类测量的UHF RFID传感器。该传感器基于商业RFID标签的天线与暴露于环境的铜层之间的耦合。通过在气候室内的曝光测试来证明，提出的传感器对金属厚度变化敏感的金属厚度敏感。在偶极天线和薄金属层之间耦合的情况下，进行了电磁模拟支持结果。
The environmental corrosiveness is governed for indoor applications by the presence of gaseous pollutants in air and levels of temperature and relative humidity. Its determination is a challenging task and requires the monitoring of thickness reduction of selected metals in the range of few tens of nanometers. The present work aims at developing an UHF RFID sensor dedicated to such measurements. The sensor is based on the coupling between the antenna of a commercial RFID tag and a thin layer of copper exposed to the environment. The ability of the proposed sensor to be sensitive to a variation of the metal thickness in the range of tens of nanometers is demonstrated experimentally through exposure tests in a climatic chamber. The results are supported by electromagnetic simulations performed in the case of a coupling between a dipolar antenna and a thin metallic layer.
