The hottest sensors in China should strive for thr

In 2012, China's sensors should strive for three strategic goals

China's sensor technology and products have been greatly improved through development. There are more than 1600 enterprises and institutions engaged in the research, development and production of sensors across the country. However, compared with foreign countries, the variety and quality level of our sensor products can not meet the needs of the domestic market, and the overall level is still at the level of foreign countries in the early 1990s

domestic sensors still have poor scientific and technological innovation, core manufacturing technology seriously lags behind foreign countries, few products with independent intellectual property rights, incomplete varieties, and the product technology level is about 15 years behind that of foreign countries; The investment intensity is low, the scientific research equipment and production process equipment are backward, the achievement level is low, and the product quality is poor; Science and technology are divorced from production, which affects the transformation of scientific research achievements. Comprehensive strength 1 The main function of the tension machine is low, and the industrial development momentum is insufficient

by 2012, the sensor field should strive to achieve three strategies 6 Big goal of clearance between force measuring piston and force measuring cylinder:

develop original technologies and products with independent intellectual property rights in the key service fields of industrial control, automobile, communication and environmental protection, with sensors, elastic components, optical components and special circuits as the key objects. Based on MEMS technology and relying on integrated, intelligent and networking technology, strengthen the development of manufacturing technology and new sensors and instrument components, so that the leading products can reach and approach the advanced level of similar foreign products. With the main goal of increasing varieties, improving quality and economic benefits, accelerate industrialization, so that the variety share of domestic sensors reaches 70%~80%, and the high-end products reach more than 60%

sensor development priorities in 2012

(1) MEMS process and new generation solid-state sensor microstructure manufacturing process; Deep reactive ion etching (DRIE) process or IGP process, packaging process; Such as normal temperature bonding flip chip welding, stress free micro structure packaging, multi chip assembly process; New sensors; Such as micro silicon capacitance sensor, micro silicon mass flow sensor, aerospace dynamic sensor, micro sensor; Special pressure and acceleration sensors for automobiles, micro chemical sensors for environmental protection, etc

(2) integrated process and multivariable composite sensor microstructure integrated manufacturing process, multivariable composite sensors for industrial control, such as pressure, static pressure, temperature three variable sensors, air pressure, wind force, temperature, humidity four variable sensors, micro silicon composite strain pressure sensors, display sensors

(3) intelligent technology and intelligent sensor signal wired or wireless detection, transformation processing, logical judgment, function calculation, two-way communication, self diagnosis and other intelligent technology, intelligent multivariable sensor, intelligent electric quantity sensor and various intelligent sensors and transmitters

(4) networking technology and sensor networking technology; Networking sensor, so that the sensor has industrialized standard interface and protocol functions
