The future development trend of sensor industry

sensor technology is the cutting-edge technology of modern science and technology, and the sensor industry is also recognized as a promising high-tech industry at home and abroad. It attracts the attention of the world with its high technical content, good economic benefits, strong penetration ability, broad market prospects and other characteristics

experts in automation in China call: at present, complex systems are becoming more and more complex, and automation has fallen into a low ebb. One of the main reasons is the backwardness of sensing technology. On the one hand, it is manifested in the backwardness of sensors in sensing information; on the other hand, it is also manifested in sensors. Plastic materials not only belong to a product with low energy consumption and low pollution, but also the backwardness of sensors in intelligence and networking

the analytical instrument industry urgently needs new sensors. "Sensors. Analytical instruments are the foundation of the sustainable development of science and technology, economy and society in China. Whether in the fields of industrial process control, facility agriculture, biomedicine, environmental control, food safety, aerospace, national defense engineering and other fields, without making an uncertainty assessment of the measurement results, there is an urgent need for all kinds of new sensors" sensors as the miniaturization of information intake sources The new generation of specialized, simplified, household (even personalized) analytical instruments can realize more sensitive, more accurate, faster and more reliable real-time detection, so as to quickly change the backward situation of analytical instruments in our country

technology promotion is the guarantee and opportunity to accelerate the development of sensor technology. For decades, based on microelectronics technology, it has promoted the development of sensor technology. In the next 10-20 years, traditional silicon technology will enter a mature period (predicted to be 2014-2017). At that time, a large number of 300mm diameter silicon wafers will be used in production, which will make the low-cost manufacturing technology of silicon and the application technology of silicon get unprecedented development, This will undoubtedly provide technical support for the development and production of new sensors such as micro sensors "sensors, smart sensors". From the perspective of overall development, the traditional silicon technology will continue until 2047 (the 100th anniversary of the invention of the transistor) before it tends to saturation (i.e., reaching the limit of the characteristic size of the chip) and decline. However, the current microelectronic technology will still follow the "principle of equal scaling" and "Moore's law" Two basic laws go on, and in trying to approach the limit of traditional silicon technology, we will continue to expand the interdisciplinary horizontal application of silicon (such as MEMS) and break through the "unstable physical devices" (quantum and molecular devices), The above two major directions in the development of microelectronics technology are the main development directions of sensor "sensor technology" at present and even in the next 20 years.

at the same time, the cross integration of multi disciplines and a variety of high and new technologies has promoted the birth and development of a new generation of "sensor". For example, MEMS (the combination of microelectronics and micromachine), MOMES (the combination of MEMS and micro optics), which are currently being developed in China Smart sensors "sensors (the combination of MEMS and CPU, information control technology), biochemical sensors (the combination of MEMS and biotechnology, electrochemistry) and so on, as well as networking sensors" sensors (the combination of MEMS networking technology) and nano sensors (the combination of nanotechnology and sensing technology) that will be vigorously developed in the future are multidisciplinary A new generation of sensor "sensor" with cross integration of various disciplines and technologies.

(1) the industrialization development mode of "sensor" sensor

we should accelerate the formation of an industrialization development mode from sensor "sensor research and development to large-scale production, take the leap forward development path of combining independent innovation and international cooperation, and make China a major producer of" sensor "sensors in the world

(2) sensor "the sensor product structure will be comprehensive, coordinated and sustainable, with an increase of 12.5 and 1.2 percentage points over the same period of last year and January and October respectively.

product varieties should be inclined to high technology and high added value, especially to fill the" blank "varieties.

(3) the production scale (annual production capacity) of the enterprise will develop to economies of scale or suitable economies of scale.

general purpose sensors with large quantities and a wide range" The production scale of sensors will be 100 million per year, and the production scale of some medium-sized sensors "sensors will be 10 million per year (including more than); while the production scale of some high-end sensors" sensors and special sensors "sensors will be hundreds of thousands to millions per year.

(4) the production pattern will develop towards specialization.

the connotation of specialized production is:

1. The categories of sensors of" production sensors "are few and fine

2. Specializing in the production of a certain type of sensor "sensor series products" needed in a certain application field, in order to obtain a higher market share;

3. Specialized cooperative production of sensor enterprises.

(5) although the strength and toughness of aerogel are low, the problems of aerogel gel limit its wide range of utilization in the current building energy conservation, and the mass production technology is developing towards automation.

sensors "have a wide range of categories and varieties, The variety of sensitive materials used determines the diversity and complexity of the sensor "sensor manufacturing technology. Looking at the overview of the current sensor" sensor process line, most of the processes have achieved single machine automation, but there are still many difficulties from the full automation of the production process, which need to be broken through by the extensive use of CAD, cam, advanced automation equipment and industrial robots in the future

(6) the key technological transformation of enterprises should strengthen the transfer from relying on imported technology to the digestion and absorption of imported technology and independent innovation

(7) enterprises should speed up the leap forward development from the domestic market to the international direction of combining domestic and foreign markets

(8) the enterprise structure will develop into a pattern of "large, medium and small enterprises at the same time" and "the coexistence of collectivized and specialized production"
