Electrochemical impedance spectroscopy (EIS) has been used in various applications, such as metal corrosion monitoring. However, many conventional corrosion monitoring setups are bulky and inconvenient for in-situ testing. The purpose of this work is to reduce the size of the whole corrosion monitoring system. We utilized EIS to design a field deployable impedance-based corrosion sensor (FDICS), capable of performing in-situ EIS analysis. Experiments verified the sensor's accuracy, and the results showed that the sensor performed similarly to a bench-top EIS machine when we tested on circuit models. Furthermore, we used the proposed FDICS to monitor a metal corrosion experiment and performed EIS. The result showed that the proposed FDICS is able to obtain the sample's impedance spectroscopy, which could help researchers test its corrosion severity on a metallic sample in-situ. Compared to other bulky conventional setups, our device eliminates the design complexity while still showing insights into the corrosion reaction.
电化学阻抗谱（EIS）已在各种应用中得到应用，例如金属腐蚀监测。然而，许多传统的腐蚀监测设备体积庞大，不便于现场测试。本工作的目的是减小整个腐蚀监测系统的尺寸。我们利用 EIS 设计了一种可现场部署的基于阻抗的腐蚀传感器（FDICS），能够进行现场 EIS 分析。实验验证了传感器的准确性，结果表明，当我们在电路模型上进行测试时，该传感器的性能与台式 EIS 机相似。此外，我们使用所提出的 FDICS 来监测金属腐蚀实验并进行 EIS 分析。结果表明，所提出的 FDICS 能够获得样品的阻抗谱，这有助于研究人员在现场测试金属样品的腐蚀严重程度。与其他庞大的传统设备相比，我们的设备在消除设计复杂性的同时，仍然能够深入了解腐蚀反应。
