However, one of the disadvantages of typical metallic materials is that they are easily corroded, especially when exposed to an electrolyte solution, resulting in electrochemical corrosion on the surface 2. Compared to other bulky conventional setups, our device eliminates the design complexity while still showing insights into the corrosion reaction.ĭue to their excellent electrical conductivity, thermal conductivity, and ductility, metallic materials, such as steel, have been widely used in making oil pipes 1. 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. Furthermore, we used the proposed FDICS to monitor a metal corrosion experiment and performed EIS. 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. We utilized EIS to design a field deployable impedance-based corrosion sensor (FDICS), capable of performing in-situ EIS analysis. The purpose of this work is to reduce the size of the whole corrosion monitoring system. However, many conventional corrosion monitoring setups are bulky and inconvenient for in-situ testing. Electrochemical impedance spectroscopy (EIS) has been used in various applications, such as metal corrosion monitoring.
