With the upgrading of sensor technology, it will be used in almost all walks of life, and as the most basic component of instrumentation and automation systems, in recent years, sensors and instrumentation components have made rapid development, there are also many problems, and presents a variety of new technology trends.

　　Data show that at present, about 6000 kinds of sensor products in our country, and foreign has reached more than 20000, far from meeting the needs of the domestic market. High-end sensor imports accounted for 80% , sensor chip imports is 90% , domestic gap is huge. Among them digitization, intellectualization, miniaturization and so on high-tech product serious shortage. The high-end products for the country's major equipment mainly depend on imports. But involves the national security and the important project to need the sensor and the intellectualized instrument and meter, the foreign often takes the restriction to our country.

　　In fact, our sensor industry has formed advantages in some fields. Xianshi technology, Yuanwanggu and other enterprises in the ultra-high-frequency RFID products occupy 90% of the domestic market share. According to XIANGCAI Securities Research Report, Hanwei electronic gas sensor market share of up to 60% , gas detection instruments market share of up to 9% .

　　In modern industrial production, especially in the process of automatic production, various sensors are used to monitor and control various parameters in the production process so as to make the equipment work in a normal or optimal state, and make the products reach the best quality. Therefore, it can be said that without a large number of good sensors, modern production will lose the foundation.

　　The problems of sensors and instrument components in our country are mainly manifested in the lack of scientific and technological innovation, especially in the fields of core manufacturing technology and key components development. In addition, our country also has the big disparity in the product quality, the level as well as the scientific research achievement transformation and so on, causes the industry development to be insufficient, these all brought the resistance for our country instrument industry future development.

　　In the future, our country will focus on sensors, elastic components, optical components and special circuits to serve the industrial control, automobile, communication, environmental protection and other fields, we will vigorously develop integrated, intelligent and networked technologies based on MEMS technology, especially to enhance the capability of independent innovation.
