Editor's note: as the requirements for the accuracy, performance and stability of gas sensors are higher and higher in the fields of industrial production, family safety, environmental monitoring and medical treatment, the research and development of gas sensors are becoming more and more important. With the application of advanced science and technology to avoid cold winter and hot summer, the development trend of gas sensors is miniaturization, intelligence and multifunction

in recent years, due to the increasingly high requirements for the accuracy, performance and stability of gas sensors in the fields of industrial production, family safety, environmental monitoring and medical treatment, the research and development of gas sensors are also becoming more and more important. With the application of advanced science and technology, the development trend of gas sensors is miniaturization, intellectualization and multifunction. The development direction of gas sensors is to deeply study and master the characteristics and interactions of organic, inorganic, biological and various materials, understand the working principle and action mechanism of various gas sensors, correctly select the sensitive materials of various sensors, and flexibly use micromachining technology, sensitive film forming technology, microelectronics technology, optical fiber technology, etc., so as to optimize the performance of sensors

the base material of the new gas sensing material and the copper alloy new material developed by gongguoliang copper material is the research and development of copper art

the research on the gas sensor material shows that the metal oxide semiconductor materials Zn0, silo2, Fe203, etc. have tended to mature, especially in the gas detection of C ratio, C2H5OH, Co, etc. At present, the work in this area mainly has two directions: one is to use chemical modification methods to dope, modify and surface modify the existing gas sensitive film materials,

and improve and optimize the film-forming process to improve the stability and selectivity of gas sensors; The second is to develop new gas sensitive membrane materials, such as composite and mixed semiconductor gas sensitive materials and polymer gas sensitive materials, so that these new materials have high sensitivity, high selectivity and high stability for different gases. Due to the advantages of rich materials, low cost, simple film making process, easy compatibility with other technologies, and working at room temperature, organic polymer sensitive materials have become a research hotspot

development of new gas sensors

using traditional action principles and some new effects, giving priority to crystal materials (silicon, quartz, ceramics, etc.), adopting advanced processing technology and microstructure design, developing new sensors and sensor systems, such as the development and use of optical waveguide gas sensors, polymer surface acoustic wave and quartz resonant gas sensors, and the research of microbial gas sensors and biomimetic gas sensors. With the application of new materials, new processes and new technologies, the gas sensor has laid the foundation for sustainable development, and its performance has become more perfect, making the miniaturization, miniaturization and multifunction of the sensor have the advantages of good long-term stability, convenient use and low price

intelligent gas sensor

with the continuous improvement of people's living standards and the increasing attention to environmental protection, the detection of various toxic and harmful gases, the monitoring of air pollution, industrial waste gas and the detection of food and living environment quality all put forward higher requirements for gas sensors. The successful application of nanotechnology, thin film technology and other new material development technologies provides a good prerequisite for the integration and intelligence of gas sensors. Gas sensors will be developed on the basis of making full use of multi-disciplinary integrated technologies such as micromachine and microelectronics technology, computer technology, signal processing technology, sensing technology, fault diagnosis technology, intelligent technology and so on. It will be an important research direction in this field to develop a fully automatic digital intelligent gas sensor that can monitor multiple gases at the same time
