The hottest sensor industry in China urgently need

  • Detail

With the rapid development of electronic information industry, the application of sensor technology is becoming more and more extensive. Industry experts predict that the next 10 to 20 years will be a strategic opportunity for the comprehensive, coordinated and sustainable development of China's new sensor technology industry. How to seize the opportunity and take effective measures to promote the healthy development of the sensor industry and make it a new economic growth point has become an important topic

sensor Market: promising

sensor is a detection device composed of sensitive elements and conversion elements that can convert electric or non electric quantities into measurable electric quantities. If computer is compared to human brain, communication is neural network, then sensor is human sensory organ, and the information it collects is of decisive significance for the thinking and processing results of computer brain

high accuracy with the development of information technology, sensors have also been widely used. Almost every modern project in industry, agriculture, aerospace, military and national defense, from land to sea, from sky to space, from various complex engineering systems to the daily necessities of life, is inseparable from various types of sensors. As the main component of information collection and transmission, sensor has become one of the three pillars of modern information technology system. This is also an important reason why many industrialized countries regard sensor technology as the focus of future scientific research and development

according to statistics, at present, about 40 countries in the world are engaged in the research, production and application development of sensors, with more than 6000 R & D institutions. Among them, the United States, Japan, Russia and other countries have strong strength. The United States, Japan, Russia and other countries have established sensor industries including physical quantity, chemical quantity and biomass, with more than 4000 R & D and production units and more than 20000 products. Large scale production has been achieved for products with a wide range of applications, and the annual production capacity of large enterprises has reached tens of millions to hundreds of millions

in 1998, the worldwide sensor market sales reached 32.5 billion yuan, and it is expected that the sales will increase to 50.6 billion dollars in 2006. On the whole, the sensor shows the development trend of multi-function, miniaturization, integration accuracy to 0.1mm, intellectualization and networking

China: backward technology is the bottleneck

China's sensor technology and industry have also achieved rapid development in recent years with the support of a series of policies and funds, such as the country's efforts to strengthen the development of sensors and their universal application in the national economy. At present, there are 1688 sensor R & D institutions, with about 6000 kinds of products and an annual output of more than 1.32 billion, of which about 1/2 of the products are sold abroad. It is estimated that by the end of the tenth five year plan, the total annual output of sensitive components and sensors is expected to reach 2billion pieces, and the total sales volume will reach about 12billion yuan

although China's sensor technology and its industry have developed rapidly, there is still a big gap compared with developed countries. It is mainly manifested as follows: first, the industrial foundation is still very weak, and the development of various types of sensors is uneven; Second, the technical grade of products is low, and the varieties and specifications are not complete; Third, technological innovation ability is weak, investment intensity is low, and key technologies are controlled by others; Fourth, the market share is low, and a considerable part of medium and high-end products are occupied by foreign companies; Fifth, the enterprise management mechanism is not active and the economic efficiency is low. The comprehensive competitiveness of China's sensor industry in three aspects: scientific and technological investment (funds, senior talent resources), industrial environment (world market share, industrial structure, enterprise scale, marketing ability) and scientific and technological strength (number of patents, new product development cycle, key materials and components that meet the standard, and production capacity) is far lower than that of the United States, Japan, Europe and other developed countries

in 1992, the Ministry of science and technology of the people's Republic of China put forward the proposal on the development of electronic sensitive technology, which has played a great role in promoting the development of sensor technology. However, due to the limitations of many factors, the industrialization speed has been slow, so that China's sensor technology not only lags behind the development of computer technology, but also has become China's electronic information technology, biotechnology, nuclear technology, aerospace technology Constraints of the development of new materials and automation technology. At the national high-level automation strategy seminar held in 2002, many experts in automation called for: at present, the system is becoming more and more complex, and automation has fallen into a low ebb. One of the main reasons is that the sensor technology is backward. On the one hand, it shows that the sensor is backward in sensing information; On the other hand, it also shows that the sensor itself lags behind in intellectualization and networking

scientific strategy is the key to guiding innovative technology

how to solve the contradictions and problems faced by the development of sensors in China? Experts believe that scientific sensor development strategies should be formulated, with centralized investment and key support, to speed up the industrialization of sensor technology

Wang Liding, an academician of the Chinese Academy of Sciences and professor of Dalian University of technology, believes that technically, the sensor will develop towards the application of microelectromechanical system (MEMS) technology, the adoption of new sensitive materials, the expansion of the application fields of sensitive components and sensors, and the introduction of nanotechnology. In terms of industrial development, the development trend of sensors is to develop towards industrialization in terms of mode, comprehensive, coordinated and sustainable development in terms of sensor product structure, economies of scale or appropriate economies of scale in terms of enterprise production scale (annual production capacity Zhejiang market charge 1560 ⑴ 590 yuan/ton), specialization in terms of production pattern, and automation in terms of sensor mass production technology, The key technological transformation of the enterprise has been continuously strengthened, the enterprise operation has leaped in the direction of internationalization, and the enterprise structure will develop to the pattern of large, medium and small enterprises, and the coexistence of collectivization and specialized production

Dr. fanmaojun, director of the 49th Research Institute of China Electronics Technology Corporation, believes that sensor technology has developed from traditional physical type to functional technology complex type, miniaturization, multifunction, digitization, intellectualization, systematization and networking, and the application field has also rapidly shifted from the high-tech and military fields in the 1990s to the traditional basic industrial transformation, large-scale engineering system matching, automobile electronization matching, home appliance control system Various fields of national economy, such as medical and health care, health care, environmental monitoring and governance, have attracted great attention of governments all over the world, especially in western developed countries, sensor technology is regarded as a key technology related to scientific and technological progress, economic development and national security. At present, some sensitive components and sensor products in China have certain international competitiveness. How to make the development of the sensor industry play an important role in the transformation and upgrading of traditional industries, government departments and the industry should pay attention to this issue

fan Maojun also believes that in order to achieve leapfrog development in the sensor industry, we must establish a sense of innovation, vigorously strengthen the development of new sensors, closely combine China's national conditions and market development needs, strive to develop new sensors with high new technology content and independent intellectual property rights, improve the performance price ratio of products, accelerate the transformation of scientific research achievements, and accelerate the industrialization of new sensors, Rapidly increase the market share of domestic sensors and narrow the gap with developed countries at a faster speed. He believes that taking MEMS technology as the core, developing new sensors and Microsystems, and replacing traditional sensor products with MEMS products is an important way to promote the development of sensor industrialization-
