The Development Status of Sensor Technology

The 21st century is a new stage towards an information society. Among them, the rapid development of optoelectronic informatics and biology has become an important symbol of scientific and technological development during this period, and there is the most opportunity to seek greater breakthroughs and leaps. Sensor technology, as an emerging discipline closely related to modern science, is seeking unprecedented and rapid development in the critical stage of humanity entering the new century and the information society. To a large extent, it depends on the in-depth research and widespread application of sensors in these two cutting-edge fields. In foreign countries, photoelectric sensor technology has been widely used in military technology, aviation and aerospace Detection technology and vehicle engineering are various fields. For example, in military affairs, the rapid development of laser guidance technology abroad has greatly improved the accuracy of missile launch and the accuracy of hitting the target; In the field of aerospace, the United States has developed a new type of high-precision and high durability infrared temperature sensor, which can still accurately measure the temperature of various parts of the operating aircraft in harsh environments; Most foreign urban traffic management also uses electronic infrared photoelectric sensors for road accident detection and troubleshooting command; At the same time, foreign existing cars are often equipped with new photoelectric sensors, such as laser anti-collision radar, infrared night vision devices, fiber optic gyroscopes that measure engine fuel characteristics, pressure changes, and are used for navigation. In China, the sensor industry is developing rapidly, and the sensor market has been continuously growing in recent years.

Mainly used in industrial manufacturing, automotive products, electronic communication, and specialized equipment, with industrial manufacturing and automotive products accounting for one-third of the market share. Sensors have brought unlimited business opportunities to the rapid development of our country, with large sensor companies such as Siemens, Honeywell, Keller, and Yokogawa entering the Chinese market. This has brought great convenience to industrial equipment manufacturers and end consumers of sensors in the automotive manufacturing industry, but also put great pressure on the domestic sensor industry. The main problems with domestic sensor products are: limited variety and poor quality; Manufacturing technology is relatively backward; Production enterprises do not master advanced core manufacturing technologies; The conversion rate of scientific research achievements for high-performance sensors is relatively low.

There are a wide variety of sensor products in China, with the main products being:Load cells, temperature sensorsPressure sensors, displacement sensors, weight sensors, flow sensors, liquid level sensors, oxygen sensors, force sensors, gas sensors, analytical instruments, etc., as well as safety sensors such as proximity/positioning sensors, safety door switches, rotary encoders, visual sensors, speed sensors, acceleration sensors, etc., are used in industrial production. Therefore, the variety field for developing sensors is very broad. The market for sensors in China has been continuously growing in recent years, with a general growth rate of over 25%. Due to the reform and opening up, China's huge market has attracted manufacturers from various countries, such as Siemens, Yokogawa, Honeywell, Omron, Bonner, etc. This has brought great convenience to end users and industrial equipment manufacturers. Although there has been development in the production of sensors and detection instruments in China, this is far from keeping up with the demand of the situation. The scale of sensor production and research and development in various countries is constantly expanding. With the development of microelectronics technology, sensor technology is developing rapidly. China's research and development efforts still need to be heavily invested, especially in strengthening the innovative development of sensors with independent intellectual property rights. The transformation of scientific research achievements and the industrialization of sensor production are even more urgent issues in China. In the case of mass production, controlling the performance of sensor products (mainly stability and reliability) to meet the requirements of commercial industry requires advanced manufacturing processes and highly automated process equipment. Therefore, efforts should be made to develop specialized process equipment to solve the problem of sensor production industrialization; Ldquo; Bottleneck& Rdquo; Question. In the application of sensors, especially new types of sensors, efforts need to be made to promote them. The reform and opening up have created market economy conditions, and various industrial equipment has applied advanced sensors, which has expanded the sensor market and provided impetus for the industrialization of new sensor production in China.

Since the 21st century, humanity has fully entered the information age, in a sense, it has entered the era of sensors. The Internet of Things industry, which is currently receiving international attention, has a particularly prominent dependence on sensor technology. It can be seen that as an important iconic industry in international competitive strategy, sensors have attracted the attention of countries around the world due to their high technological content and broad market prospects. The development of the sensor industry not only provides support for the Internet of Things, but also plays a positive role in the transfer and technological upgrading of traditional industries, as well as in the current economic restructuring and transformation. At the same time, the development of the Internet of Things industry has also expanded a huge market space for the improvement of sensor technology and industrial development.
