Gas Sensor Based on Micro-nano Fiber Evanescent Field Effects
With the development of economy and technology,demands and requirements for gas detection are increasing.Conventional detection methods including catalytic combustion,gas chromatography and thermal conductivity analysis have shortcomings of low corrosion resistance,easy-to-drift sensors,slow response,etc.To address these shortcomings,the gas detection based on evanescent fields of micro-nano fibers has been studied.In terms of measurement principles,evanescent field distribution of micro-nano fibers has been analyzed.Also,this study investigates the research progress both at home and abroad and summarizes the advantages and shortcomings for the current gas detection technology based on micro-nano fiber evanescent field effects.Micro-nano fibers provide advantages of strong evanescent fields,good flexibility,small loss,etc.It's promising to apply and promote micro-nano fiber-based sensors in the detection fields of industrial process,environmental protection,medical treatment,etc,if the application problems are solved with the development of micro-nano fiber technologies.
