Chen Dapeng, deputy director of China Internet of Things Research and Development Center introduced MEMS technology is an integral part of the Internet of Things industry chain, but because of the sensor industry, high technology threshold, engaged in sensor research and development of innovative companies despite some of the core technology, but small , There is no production capacity, coupled with the lack of domestic open, professional production platform, most of the sensor products in prototype development, trial production or small batch production stage, with foreign companies in a competitive disadvantage.
The current MEMS market leading products for pressure sensors, accelerometers, micro-gyroscopes, ink nozzles and hard drive head and so on. Most industry observers predict that the next five years, sales of MEMS devices will show a rapid growth trend, the annual average rate of increase of about 18%, so the mechanical electronic development engineering, precision machinery and equipment, semiconductor physics and other disciplines to provide a very Good opportunities and harsh challenges.
MEMS sensor technology With the development of information technology requirements become more stringent, the global MEMS sensor market with Tablet PC and mobile phone growth has slowed down. Affected by the global economic slowdown, the global MEMS sensor market slowed down. It is estimated that the average annual compound growth rate will be 8% in the next few years. The major growth drivers come from the field of consumer electronics, especially mobile phones and the increase in the field of automotive electronics Slow; the next few years, tablet PC and smart phone MEMS sensor applications will continue to maintain strong growth, but the retail price of the product is gradually declining.
With the rapid development of China's automotive electronics, new digital consumer electronics and medical electronics industries, the demand for sensors in the domestic market shows a rapid growth trend. According to the China Electronics and Information Industry Development Research Institute predicted that the next five years the domestic sensor market compound annual growth rate will exceed 30%. The market for sensors in the areas of automobile, logistics, mining exploration, coal mine safety supervision, security and RFID tagging card increased rapidly. Overall, China's sensor market has a bright future.
In this context, the smart sensor technology represented by MEMS has been rapidly developed. Compared with the traditional sensor technology, MEMS, small size, light weight, low cost, low energy consumption, high reliability, easy mass production, high intelligence. Now is in rapid development MEMS technology in the future development in the following areas:
First, miniaturization while reducing power consumption. Will appear micron or even nano-scale micro-devices, while reducing power consumption; Second, the miniaturization while improving accuracy, the MEMS accelerometer quartz accelerometer noise characteristics to ensure the small size of the MEMS gyroscope access to fiber optic gyroscope Instrument bias stability, and can provide much better than the impact resistance of fiber optic gyroscope; Third, the trend of integration and intelligence, that is, MEMS and IC integrated manufacturing technology and multi-parameter MEMS sensor integrated manufacturing technology has been developed , And make the signal detection have some automation on the basis of the integration. These trends require semiconductor manufacturers to provide highly-integrated, highly-stable, smart, and highly integrated MEMS sensor modules that are more accurate, stable and reliable.
Driven by the Tablet PC and smart phone market, the market share continues to rise, of course, many of these sensor technology consumption sources and the adjustment of our market. Affected by the sluggish global economy and cautious macroeconomic policies in China, the MEMS sensor market in China showed a slowdown in 2011, but still significantly higher than the global growth rate. The MEMS sensor market in our country is now slowing down with a good development trend . These stable developments have been attributed to the further increase of penetration rate of MEMS sensors in consumer products.
Although our country has a stable and solid sensor market, but as a sensor business more should recognize the development direction of MEMS sensor technology. First, the sensor technology is the need to develop to high precision, such as how to accurately detect the sensor guidance, and our sensor is to high reliability, wide temperature range, and the development of miniaturization, a variety of portable devices on the sensor More should be to consider these aspects. Finally, our sensor technology is still to the micro-power and passive, to the network development, and wireless technology, to the intelligent digital development, combined with the CPU and so on, science and technology development in one direction also depends on these aspects, energy control and The combination of intelligence are all MEMS sensor technology necessary.
The agencies forecast that MEMS will maintain double-digit steady growth in the next six years: revenue will grow at a compound annual rate of about 20% and shipments will grow at a compound annual growth rate of about 13%. By 2017, the global MEMS The market size can reach 21 billion US dollars.
