What are the technical characteristics of the sensor?

  China's sensor industry is in the critical stage of development from traditional to new sensors. It reflects the general trend of new sensors to miniaturization, multi-function, digital, intelligent, systematic and networked. Sensor technology has evolved over the years and its technology development can be divided into three generations:

  The first generation is a structured sensor that uses structural parameter changes to sense and transform signals.

  The second generation is a solid-state sensor developed in the 1970s. It consists of solid components such as semiconductors, dielectrics, and magnetic materials. It is made of certain properties of the material. Such as: using thermoelectric effect, Hall effect, photosensitive effect, respectively, made of thermocouple sensor, Hall sensor, photosensitive sensor.

  The third-generation sensor is a smart sensor that has just been developed in the future. It is a combination of microcomputer technology and detection technology, which makes the sensor have certain artificial intelligence.

  Sensor technology and industry characteristics

  The characteristics of sensor technology and its industry can be summarized as follows: basic and application depend on two; technology and investment are two intensive; product and industry are scattered.

  Basic and application

  Foundation attachment means that the development of sensor technology is based on the four cornerstones of sensitive mechanisms, sensitive materials, process equipment and measurement technology. Sensitive mechanisms vary widely, sensitive materials vary, process equipment is different, measurement technology is very different, without the support of the above four cornerstones, sensor technology is difficult to sustain.

  Application dependency means that sensor technology is basically an application technology. Its market development relies on the application of detection devices and automatic control systems to truly reflect its high added benefits and form a real market. That is to say, the development of sensor technology should be market-oriented and demand traction.

  Two intensive technologies and investments

  Technology intensive refers to the diversity, marginality, comprehensiveness and skill of the technology in the development and manufacturing process of the sensor. It is a collection of high-tech products. Due to the intensive technology, it also naturally requires talent intensive.

  Investment-intensive refers to the research and development and production of a certain sensor product requires a certain investment intensity, especially in engineering research and the establishment of economies of scale production lines, but also require greater investment.

  Two major products and industries

  The two major dispersions of product structure and industrial structure refer to a wide variety of sensor products (a total of 10 categories, 42 categories of nearly 6,000 varieties), its application penetrates into various industrial sectors, and its development has the driving force for the development of various industries. It is also strongly dependent on the supporting role of various industries. Only by adjusting the industrial structure and product structure according to market demand can we achieve comprehensive, coordinated and sustainable development of the sensor industry.
