Experts in automation in China have called for: At present, complex systems are becoming more and more complex, and automation has fallen into a trough. One of the main reasons is the backwardness of sensing technology. On the one hand, the sensor is lagging behind in sensing information; The sensor itself is lagging behind in terms of intelligence and networking.
The analytical instrument industry is in urgent need of new sensors. Analytical instruments are the basis for the sustainable development of science and technology, economy and society in China. Whether in industrial process control, facility agriculture, biomedicine, environmental control, food safety, even aerospace, national defense engineering, etc., all kinds of new sensors are urgently needed as information intake. A new generation of analytical instruments that are miniaturized, specialized, simplified, and familyed (or even personalized) to achieve more sensitive, accurate, faster, and more reliable real-time detection to rapidly change the backwardness of analytical instruments in China. .
Technology promotion is the guarantee and opportunity to accelerate the development of sensor technology. For decades, based on microelectronics technology, the development of sensor technology has been promoted. In the next 10 to 20 years, traditional silicon technology will enter maturity (predicted from 2014 to 2017). At that time, 300mm diameter silicon wafers will be used in production, which will lead to unprecedented development of low-cost silicon manufacturing technology and silicon application technology, which will undoubtedly provide technical support for the development and production of new sensors such as micro sensors and smart sensors. In terms of overall development, traditional silicon technology will continue to be saturated (ie, reach the limit of chip feature size) and decline until 2047 (ie, the 100th anniversary of transistor invention). At present, microelectronics technology will continue to follow the two basic laws of "equal scaling principle" and "Moore's Law", and continue to expand the interdisciplinary horizontal application of silicon (such as MEMS) and breakthrough in the process of trying to approach the limits of traditional silicon technology. "Unsteady physical devices" (quantum, molecular devices), and the two major directions in the development of the aforementioned microelectronics technology are the main development directions of sensor technology for the current and future 20 years.
At the same time, the interdisciplinary and multi-technical cross-integration has promoted the birth and development of a new generation of sensors. For example: MEMS (the combination of microelectronics and micromachines), MOMES (combination of MEMS and micro-optics), smart sensors (combination of MEMS and CPU, information control technology), biochemical sensors (MEMS and biology) The combination of technology and electrochemistry, and the networked sensors (combination of MEMS network technology) and nanosensors (the combination of nanotechnology and sensing technology) that will be developed in the future are all new interdisciplinary and multidisciplinary technologies. A generation of sensors.
(1) Sensor industrialization development model.
It is necessary to accelerate the formation of an industrialized development model from sensor research and development to large-scale production, and take the leap-forward development path combining independent innovation and international cooperation, making China a major producer of sensors in the world.
(2) The structure of sensor products is comprehensive, coordinated and sustainable.
Product varieties should be tilted to high technology and high added value, especially to fill the "blank" variety.
(3) The scale of production (annual production capacity) of the enterprise is to scale economy or develop economies of scale.
