Sensors, as the cornerstone of modern information technology, play a bridging role in connecting the physical world and the digital world. However, in the development process of domestic sensors, although some progress has been made, there are still many shortcomings compared to similar foreign products. This article will delve into the shortcomings and challenges of domestic sensors, in order to provide reference for industry development.

一、 Incomplete varieties, specifications, and series

Domestic sensors are not comprehensive enough in terms of variety, specifications, and series. Domestic sensor products often find it difficult to form a complete series, resulting in many inconveniences for users when choosing. For example, high-precision and highly stable low differential pressure sensors (range ≤ 1KPa) and high differential pressure and high static pressure sensors (range ≥ 3MPa, static pressure ≥ 60MPa) commonly used in industrial automation instruments are not yet available for stable and bulk supply in China, and rely mainly on imports. In addition, in the field of automotive sensors, China needs to import more than 500000 sets of high-level sensors every year, and some special purpose and special range sensors, such as tire pressure sensors that do not require lithium batteries, are still blank in China.

二、 The industrialization process lags behind

The industrialization of sensors is the key to achieving their economic benefits, reducing costs, and stabilizing processes. However, the industrialization process of domestic sensors is significantly lagging behind. Although the country has raised the issue of mass production and industrialization of sensors since the "Seventh Five Year Plan", the efforts have been insufficient and have not been sustained. So far, there has not been a leading enterprise or benchmark unit in the sensor industry in China. There are significant differences between the application of civilian industrial sensors and military sensors. Civilian sensors focus more on cost, cost-effectiveness, and mass production, which are the shortcomings of domestic sensors.

三、 Weak basic research and insufficient innovation capability

Domestic sensors are inadequate in basic research, with a lack of development of new principles and devices, and a scarcity of research and development of new materials. The basic theoretical research on sensors in China is not given enough attention, making it difficult to obtain national project support. Even if the project is approved, the funding is often limited, making it difficult to attract outstanding talents. Enterprises are busy pursuing short-term benefits and have no time to focus on basic research; The government places more emphasis on political achievements and lacks sufficient attention to basic research on sensors. Therefore, domestic sensors lag significantly behind their foreign counterparts in mathematical model building, chip design software development, simulation, and process simulation.

四、 Common key technologies have not yet been broken through

Domestic sensors have not yet made substantial breakthroughs in common key technologies. The problems of multiple design software issues, poor mass production capabilities, weak standards, and outdated production process equipment are still prominent. Although there is a set of MEMS sensor design software in China, there are still many problems and a significant gap from its practical application. In addition, the low reliability of domestically produced sensors is one of the main reasons affecting their widespread application. Almost all important production lines such as the power and petrochemical sectors use foreign sensors and dare not use domestic products.

summary

In summary, domestic sensors still have many shortcomings and challenges in terms of variety, specifications and series, industrialization process, basic research and innovation capabilities, and common key technologies. The solution to these problems requires joint efforts from the government, enterprises, and research institutions to increase research and development investment, promote technological innovation, and industrial upgrading. Only in this way can domestic sensors occupy a place in the domestic and even international markets, providing strong support for the country's information construction and the smooth promotion of strategic emerging industries.
