summarize

our countrytransducersManufacturing industry development began in the 1960s, in 1972, the establishment of China's first batch of piezoresistive sensor development and production units; in 1974, the development of China's first practical piezoresistive pressure sensors; in 1978, the birth of China's first solid-state piezoresistive acceleration sensors; in 1982, the earliest domestic silicon micro-mechanical systems (MEMS) processing technology and SOI (Silicon on Insulator) technology research. (Silicon on Insulator) technology research.

With the development of the Internet of Things, the device for the increasing demand for sensors, China, although the development of sensors late, but over the years as China's economy continues to improve, the national policy level of support, and gradually emerged as a number of sensor suppliers.

According to the data disclosed in the Blue Book of Sensor Development in China:China's sensor development and foreign brands there is still a big gap between the proliferation of domestic low-end sensors, homogenized competition is serious, mostly OEM production, the core technology of the sensor chip accounted for a low percentage of the core technology of the sensor chip and other core technology is highly deficient in China's sensor industry is the current status quo.Therefore, in the global sensor industry's international pattern position, our country is still in the third echelon, far behind the United States, Japan, Germany and other advanced countries in the sensor, the average gap of at least 10 ~ 15 years above. In the sensor we still have a long way to go.

• Outdated sensor design technologyThe main design software isCoventorWare(CoventorWare from the U.S. company Coventor, is currently the world's MEMS simulation and modeling solutions leader, almost all of China's MEMS chip companies use this software for design) and IntelliSuite (U.S. company, is also one of the world's first MEMS design software)
• Process and materials technologyIs one of the most important key factors affecting the performance of the sensor, planar process, thick film process, ultra-fine powder preparation process, micro-machining process, intelligent chip manufacturing process and other important sensor process technology, our country from the "Sixth Five-Year Plan" has begun a number of research and development work in solving the relevant sensor process manufacturing problems have been achieved. Certain results. However, some of the key materials, key accessories still need to be imported, the lack of national standards, industry standards, less domestic equipment, no specialized manufacturing enterprises.
• Sensor Industrialization TechnologyThere is still a big difference, a lot of technology in the laboratory no problem, the implementation of industrialization is very different from abroad. Comparison of foreignBosch (name),Honeywell (name),Infineon Technologies,Yokohama River,Gaines (name),Omron (brand),sycophant,STMicroelectronics,Siemens (company name),E+H...... and other sensor benchmarking enterprises, there is almost no domestic sensor companies with the same level of counterparts, these companies occupy China as well as the world 99% above the middle and high-end sensor market share.
• Sensor Application TechnologyIn the field, China also has a big gap, according to the data released by the prospective industry research, the global sensor market , the United States occupies 29% share, Japan 21%, Germany 19%, China 10%. and China's share of the sensor is mainly concentrated in the low-end market.
