Abstract:

Compared with the traditional monitoring methods, the use of electrochemical sensors for real-time monitoring of civil engineering structure has a series of advantages. The real-time monitoring of civil engineering structure by using electrochemical sensor can find out the problems timely and effectively and put forward the corresponding protective and resolving measures to provide guarantee for the sustainable development of the economy. It is one of the most suitable ways for China’s national conditions and economic development at this stage. In order to clarify the research status and development space of electrochemical sensor in civil engineering monitoring, combined with the engineering monitoring requirement of structural engineering durability, geotechnical contaminant and soluble salt ion concentration and the problems that need to be solved at present, the application and research of the  electrochemical sensors at home and abroad are analyzed comprehensively, and the effects of current manufacturing methods on the  performance of electrochemical sensors are summarized in detail. Results demonstrate that the selection of suitable materials, the development of reasonable manufacturing processes, and the research and development of electrochemical sensors with long term  stability, high efficiency and cost effective need to be based on the requirements of research field.
