IC will advance the development of the sensor industry chain

As a source of many public information, smart sensors can collect and process information in different areas such as the Internet of Things, smart industry, smart agriculture, intelligent transportation, smart grid, smart medical care, smart environmental protection, smart logistics, smart security, and smart home. Analysis and transmission are one of the most important electronic devices that are in urgent need of development.

So what is a smart sensor? A sensor is an electronic device that simulates human senses and collects external information. The intelligence of a sensor is like the realization of some functions of the human brain and nervous system. From the sense to the process of thinking, it is called “wisdom”; the result of wisdom is produced. Behavior and language, and the process of expression of behavior and language is a kind of “ability”, both of which are collectively called “smart”. The connotation conferred on the sensor intelligence can have multiple levels and degrees. Like the performance of human intelligence and ability, the “intelligence quotient” and “energy quotient” can be used to describe the extent to which intelligence is exerted in an individual. Therefore, the intelligence and ability of smart sensors will also evolve from a simple naive stage to a complex abstraction stage. Sensors that can simulate some functions of the human brain and nervous system to some extent are called smart sensors. Sensors that have certain functions for information processing, analysis of detected parameters, or the ability to store information or convert information analysis results into other instructions can all be called smart sensors. For example, the technology and the sensor are combined with the microprocessor, and the sensor's sensitive element, its signal conditioning circuit and the microprocessor are integrated on a single chip. This can be called a sensor with preliminary intelligence. Smart sensors combine ASIC circuits, microprocessors, communication interfaces, and software protocols with sensitive chips to make the most sensitive use of sensitive chip sensing information.

Integration, miniaturization, multi-functionalization, intelligence, and networking are trends in the development of sensors, but integration and miniaturization are the basis of this trend. Only integrated and miniaturized technologies can achieve low-cost, low-power consumption, High performance, versatility, intelligence and networking. Therefore, from the foundation of this implementation, intelligence and networking are the goals, and integration and miniaturization are the means to achieve this goal. Based on the integration and miniaturization technologies, more advanced intelligence factors are integrated into an overall structure. This is the smart microsystem. Intelligent microsystems require more integration of subject knowledge and technology.

As a whole, the major bottleneck in the development of miniaturization and integration of the current domestic sensor industry is the lack of capacity in China's IC and MEMS technology industry chain. Both in terms of technical quality, production capacity, and the scale of production, are far behind the international advanced technologies. bigger. As far as the sensor products are concerned, despite the strong single product technology, overall, there are still low reliability, lack of research on basic technologies and manufacturing processes, backward product performance and functions, long product technology update cycles, and bottom-up application requirements. Design basic issues such as less. China's scientific research and development level of sensors is about 5 to 10 years behind the developed countries, and production technology is about 10 to 15 years behind.

Smart sensors are currently the hotspots and frontiers of sensor research in the world. To vigorously carry out smart sensor research is a leap-forward development approach that we should adopt, and it is a key measure for ushering in the strategy of the future of information technology. The public information market is a huge market for smart sensor applications. Taking market demand as the traction and expanding the information consumer market to promote the smart sensors in China is very straightforward. Under the support of the State Council’s “Some Opinions on Accelerating the Promotion of Information Consumption and Expanding Domestic Demand,” China’s smart sensors will be developed from technology to products. It will develop faster than expected, and form a virtuous cycle in terms of technological innovation, product industrialization, and expanding market share. China's measures to expand information consumption have injected a powerful impetus for the development of smart sensors, so seizing the opportunity to substantially increase the comprehensive strength of China’s sensor research and production and establish a smart sensor high-tech industry is China’s future in the field of information technology. The important foundation of status.

Considering the layout of the national economic structure, it is necessary to focus on the systematic advancement of the entire IC and sensor industry chain, increase government support, establish an industry common technical service platform, provide support for independent innovation and sustainable development of the industry, and achieve the overall development level of the industry. Significant improvement; Encourage cross-industry joint business model, support the completion of a number of independent design, development and industrialization of high-precision smart sensors; Organizations of various research institutions to solve the key issues of intelligent and networked sensor backbone products. Breaking through the blockade technically and relying mainly on independent innovation technologies on smart sensors, it has advanced in the development of next-generation information technology.
