Sensor Technology Features

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.
