Abstract

The embodiment of the invention discloses a manufacturing method of a gas sensor, a surface acoustic wave micro-centrifugal device and the gas sensor. The manufacturing method of the gas sensor comprises the following steps: providing a surface acoustic wave micro-centrifugal device, the surface acoustic wave micro-centrifugal device comprises a micro reaction tank, and the micro reaction tank comprises a solution containing a plurality of layers of MXene materials; stripping the multi-layer MXene material, and obtaining a single-layer MXene material; providing a semiconductor gas sensing assembly, and reversely buckling a finger strip sensitive area of the semiconductor gas sensing assembly on the micro reaction tank; and coating the single-layer MXene material on the finger strip sensitive area of the semiconductor gas sensing assembly by using an acoustic flow spin-coating method to obtain the gas sensor. The gas sensor manufactured by the scheme can effectively improve the sensitivity of hydrogen sulfide detection.

Description

technical field [0001] The present application relates to the technical field of gas sensing, in particular to a method for manufacturing a gas sensor, a surface acoustic wave microcentrifuge device and a gas sensor. Background technique [0002] Hydrogen sulfide is a toxic gas with the smell of rotten eggs. It contains strong neurotoxins and has a strong stimulating effect on mucous membranes. Exposure can cause symptoms such as ophthalmia, chemical pneumonia, pulmonary edema, upper gastrointestinal discomfort, and central nervous system. , Inhalation of a small amount of high-concentration hydrogen sulfide can be fatal in a short time. Studies have shown that hydrogen sulfide may play an important role in the damage of lung function in the pathogenesis of acute and chronic lung diseases. Therefore, the concentration of hydrogen sulfide in the breath can play a key role in the diagnosis of human inflammation and related diseases. [0003] However, traditional gas sensors ...
