The Development Trend Of Sensor Industry In China

- Apr 13, 2018-

The sensor industry in China is at a critical stage of development from traditional to new sensors. It reflects the general trend of new sensors to be miniaturized, multi-functional, digital, intelligent, systematic, and networked. After many years of development, the sensor technology can be divided into three generations:

The first generation is a structural sensor that senses and transforms signals using structural parameter variations.


The second generation is a solid-state sensor developed in the 70s. This sensor consists of solid components such as semiconductors, dielectrics, and magnetic materials, and is manufactured using certain characteristics of the material. Such as: ultrasonic sensors, the use of thermoelectric effects, Hall effect, photosensitive effect, were made of thermocouple sensors, Hall sensors, photosensitive sensors.


The third-generation sensor is an intelligent sensor that has just been developed. It is a combination of micro-computer technology and detection technology, making the sensor have a certain degree of artificial intelligence.


Sensor Technology and Industrial Features


The characteristics of the sensor technology and its industries can be summarized as follows: the foundation and the application of the two attachments; the technology and investment are two intensive; the products and industry are scattered.


Foundation and application of two attachments


Fundamental dependence means that the development of sensor technology depends on the four cornerstones of sensitive mechanisms, sensitive materials, process equipment, and measurement technology. Sensitive mechanisms vary widely, sensitive materials are diverse, process equipment is different, and measurement techniques are widely divergent. There is no support for the above four cornerstones and sensor technology is difficult to sustain.


Application attachment means that sensor technology basically belongs to application technology, and its market development depends on the application of detection devices and automatic control systems, in order to truly reflect its high added value and form a realistic market. That is, the development of sensor technology should be market-oriented and implement demand traction.


Technology, investment two intensive


Technology intensive refers to the diversity, marginality, comprehensiveness, and artistry of sensors in the development and manufacturing process. It is a collection of high-tech products. Due to the dense technology, talents are naturally demanding.


Investment intensive means that investigating, developing, and producing a certain kind of sensor product requires a certain degree of investment intensity, especially when engineering research and the establishment of economies of scale production lines require greater investment.


Product and industry dispersed.


The two major dispersions of product structure and industrial structure refer to a wide variety of sensor products (a total of 10 major categories and 42 subcategories of nearly 6,000 varieties). Their application has penetrated into various industrial sectors, and its development has driven the development of various industries. , And strongly dependent on the supporting role of various industries. Only in accordance with market demand, continuously adjust the industrial structure and product structure in order to achieve a comprehensive, coordinated and sustainable development of the sensor industry.
