China's sensor applications continue to expand

In recent years, the Chinese sensor market has continued to grow at an increase rate of more than 15%. In 2012, the four major areas of China's sensor applications were industrial and automotive electronic products, communications and electronic products, and consumer electronics products. Among them, industrial and automotive electronic products accounted for about 42% of the market share. The market size reached 16 billion yuan, and the entire sensor market broke through. 500 billion yuan.

Although China's sensors have high market demand and rapid development, there are also problems such as low technical level, lack of types, and poor R&D capability. At present, there are 1,688 enterprises in China engaged in the development, production and application of sensors, but only MEMS development and production of more than 50, but the scale and application are smaller. Without sufficient application of scale, China's sensors have problems of low technology but high prices. They have lost their advantages in the international market, and have made the market more fierce.

The development of China's sensor industry is lagging behind. Domestic sensor demand, especially high-end demand, is heavily dependent on imports. Localization gap is huge. At present, the import of sensors accounts for 80%, and the proportion of sensor chip imports accounts for 90%. The demand for localization is urgent.

The industry market institutions pointed out: "At present, from the perspective of the entire gas sensor field, although the stability of the technology is large, the threshold is very low. The future direction can only be advanced." And the development of the Internet of things will greatly promote the development of the sensor field. , It will have great application in energy, intelligent perception, security monitoring, environmental protection and other fields. It is estimated that by 2020, the scale of the entire industry will reach more than 60 billion yuan, and the localization rate will reach over 70%.

The development prospects and application fields of sensors are constantly expanding. Whether it is the automation industry or the construction of smart cities, including the development trend of the Internet of Things, it is clear to the people that the sensor industry will usher in what a brilliant development. However, under such a market environment, China's sensor industry does not have a good grasp of opportunities, a low degree of localization.

In 2012, the overall scale of the development of China's sensor industry gradually expanded, and it was significantly applied in the automotive industry, including sensor applications in automotive tires, sensor applications in airbags, sensor applications in chassis systems, sensor applications in engine operation management systems, and waste gas. Sensor applications and requirements in air quality control systems, sensor applications and requirements in ABS, sensor applications and requirements in vehicle driving safety systems, sensor applications and requirements in automotive anti-theft systems, sensor applications and requirements in engine combustion control systems Sensor applications and requirements in automotive positioning systems, sensor applications and requirements in other automotive systems.

In addition, Chinese sensors also have new applications in other fields such as industrial control, environmental protection, facility agriculture, multimedia images, and other related sensor applications. Recalling the rapid development of the Chinese sensor industry, there are also some unfavorable factors.

For example, there is a weak industrial foundation in terms of product technology, a disconnect between technology and production, a low level of product technology, a lack of product types, and weak product R&D capabilities. However, on the other hand, the country continues to formulate strategies and policies that are conducive to the development of the sensor industry. The rapid development of the whole-system system market and the continuous promotion of emerging technologies have also become favorable factors for the development of sensor networks.

Because there is no large-scale application, domestic sensor products generally have the contradiction of low technology level and high price. In the international market, companies in old industrial countries such as Germany, Japan, the United States, and Russia have dominated the sensor market. Many manufacturers have achieved large-scale production. Some companies have an annual production capacity of tens of millions or even hundreds of millions. In contrast, the application range of China's sensors is narrow, and more applications still remain in basic application areas such as industrial measurement and control. Relying on this, the Chinese sensor market is very competitive.
