After nearly ten years of introduction, digestion, and absorption of foreign sensor technology, at this stage, China has formed a certain scale of sensor production capabilities, and the research and development area has expanded from a single species to light, thermal, force-sensitive, voltage-sensitive, magnetic Sensitivity, gas sensitivity, humidity sensitivity, sound sensitivity, radiation sensitivity, ion sensitivity, bio-sensitivity, and other sensor types, the main product research and development fields are basically the same with foreign countries. Among them, more than ten varieties such as thermistors, ZnO varistors, flammable gas sensors, and light-emitting diodes have formed a certain scale of production capacity.

At the "2010 China Electronic Components Market Summit" held recently, Wen Xueli, Secretary-General of the China Electronic Component Industry Association, revealed that there are more than 1,300 enterprises and institutions in China engaged in the development and production of sensors. In 2008, sales of sensitive components and sensors in China reached 47.4 billion yuan, and in 2009 it was 58.3 billion yuan, and is expected to reach 71.8 billion yuan in 2010.

At present, the production capacity of sensitive components and sensors in China has exceeded 5 billion; China Light & Power Association conducted a statistical survey on 154 sensitive enterprises and institutions in China, with a total production of 4.658 billion and sales of 14.419 billion yuan. Yuan; profit of 963 million yuan, profit growth of 12.25%.

At the same time, Wen Xueli also pointed out that the following problems exist in China's sensor industry, which cannot be ignored.

First, the scale of local companies is too small, and the impact of foreign products is severe. There are more than 1,300 institutions, research institutes, and companies engaged in the development and production of sensitive components and sensors in China. However, there are fewer backbone enterprises with more comprehensive strength in research and production, but only About 10% of the total number. The domestic market has been severely affected by foreign products. Hundreds of domestic agents of foreign sensor products make foreign goods occupy a major share in the domestic sensor market.

Second, technology tracking, independent technological innovation less China's current many companies are the use of foreign components for processing, little independent research and development of products, independent innovation ability is very weak. Even many companies only stay at the level of acting foreign products, and the development space is stretched. Domestically produced sensor companies have continued to rely on the inertia of foreign technology for a long period of time. They have formed a situation of “foreigners and strong players” in technology. They have not only lost the mid-to-high end product market, but also led directly to a single type of product that they can produce, and the homogeneity is very serious. There are even a large number of domestic products that can only imitate the shape of others. Even so, due to the low level of technology, the sensitivity, accuracy, and reliability of imitating products are far from satisfactory.

Third, the level of industrialization technology is low China's resource investment in the research and development phase of the sensor technology is relatively more important, but relatively neglected the development of basic industrialization, the development of basic technologies for productization, commercialization is seriously lagging behind, materials, manufacturing The common and basic technologies associated with and related to technology and equipment, testing, and instrumentation are disjointed from each other, restricting the progress of industrialization and lagging behind the international level by 10-15 years.

Fourth, the distribution is not balanced, a large number of small private capital domestic sensor production enterprises are mainly concentrated in Shaanxi Province as well as the eastern and coastal areas, the western region and relatively few inland areas. Of these companies, more than 90% are small businesses, many of which are also "school-run factories" run by universities and research institutes. Because there is not much need for early investment in sensor manufacturing, there are many private capital companies involved. The existence of a large number of small businesses has made the low-end sensor field and the price competition of domestic sensors have entered a tragic state. On the other hand, in the high, refined, and sharp areas, the domestic sensor operation has been bleak. Fifth, the performance of the product is relatively low price Sixth, the conversion rate of scientific and technological achievements, the process of practical application of new technologies is slow. VII. Lack of professionals The sensor industry involves many disciplines such as physics, chemistry, biology, electronics, and even computer networks, and its application fields are extensive. In the entire electronics industry, it can be said that no other product can exceed it. It is difficult to master its basic principles and apply it to production practice. Therefore, although the development prospects of the sensor industry are extremely high, there is an extreme lack of expertise in sensor technology for computers, networks, and semiconductor integrated circuit design and communications.
