Abstract

The invention relates to a toxic and harmful gas detection sensor and method, and belongs to the technical field of gas detection. The toxic and harmful gas detection sensor comprises a shell, a dielectric substrate, a sensitive dielectric film, an artificial plasmon resonator and a metal microstrip transmission band; the top of the shell is open-mouthed; the dielectric substrate is horizontally arranged and located in the shell, and the lower surface of the dielectric substrate is fixedly connected with the inner wall of the bottom end of the shell; the sensitive dielectric film is fixedly connected to the upper surface of the dielectric substrate; the artificial plasmon resonator is fixedly connected to the sensitive dielectric film; and one end of the metal microstrip transmission bandis fixedly and electrically connected with the artificial plasmon resonator, the other end of the metal microstrip transmission band penetrates the shell, and the metal microstrip transmission band isfixedly connected to the sensitive dielectric film. The gas detection sensor is small in size, low in power consumption, high in external interference resistance, easy to integrate and high in detection sensitivity.

Description

technical field

[0001] The invention belongs to the technical field of gas detection, and in particular relates to a toxic and harmful gas detection sensor and a detection method. Background technique

[0002] With the improvement of living standards, more and more architectural decorations have entered people's lives. Decoration can improve people's living quality, but it is accompanied by a large number of toxic and harmful substances contained in decorative materials. This attention is increasing day by day, so the requirements for environmentally friendly materials in the field of construction and home decoration are increasing day by day, and the market demand for various types of high-sensitivity toxic and harmful gas sensors is growing rapidly.

[0003] At present, gas sensors mainly include semiconductor gas sensors, electrochemical gas sensors and infrared gas sensors. The above-mentioned sensors all have problems such as poor detection stability and low detection ...
