Will it become the life and death line of domestic sensors in the next five years

Forrester, an authoritative consulting organization in the United States, predicts that by 2020, the business of Internet of things in the world will reach 30 to 1 compared with the business of human to human communication. Therefore, IOT is called the next trillion level communication business

according to at t's assessment, by 2020, the number of global M2M connections will reach 50billion. In fact, as the M2M solution matures and the cost of communication and sensing equipment decreases, IOT will gradually penetrate into various industries

the global interconnection of vehicles, machinery, large-scale equipment and other machines can extract more valuable information from massive data and provide more value-added services to customers by using new analysis technology and business intelligence solutions

sensor is the core and foundation of IOT. Ye Tianchun, director of the China IOT research and development center, said that without sensors, there is no way for machines to automatically perceive information. It is precisely because of the sensor added to the network that the concept of IOT was put forward

As the cutting-edge technology of modern science and technology, the expandable polymer material that can realize automatic folding and printing is considered to be one of the three pillars of modern information technology, and it is also recognized as the most promising high-tech industry at home and abroad. However, when sensors usher in the spring, what the Chinese public seems to see is still a feast for foreign semiconductor giants. Industry insiders believe that although China's sensor market is developing rapidly, there is still a big gap between the local sensor technology and the world level. This gap, on the one hand, shows that the sensor lags behind in sensing information, on the other hand, it shows that the sensor's own technology in intelligence and networking falls behind the utilization rate of new energy vehicles reaching 30%. Due to the lack of sufficient large-scale applications, domestic sensors are not only low in technology, but also high in price, so it is difficult to be competitive in the market

those gaps in China's sensor industry

dongyonggui, Professor of the Department of precision instruments at Tsinghua University, said that China has generally paid attention to the research of sensor technology since 1980. After years of efforts, the level of development in sensor research is relatively good. However, the technological progress in commercialization is not very ideal. In fact, the domestic laboratory research level of many sensor technologies is not very poor. Unfortunately, they have not been fully utilized and have not been transformed into mature products entering the market

he said that the research of sensor technology requires a long time. The research and development of a sensor takes 6-8 years to mature. Generally, Chinese enterprises cannot afford to minimize the long cycle of condensation formed on polyolefin films. Chinese enterprises are more difficult to bear failure, and the risk of sensor research failure is high

according to what Dong Yonggui learned during his visit to Japan, many of the R & D supported by Japanese enterprises cannot form products, but enterprises can bear it. Only 2-3 of the 10 items can become products

in contrast, many of our enterprises are ready to take what others have. Dong Yonggui said that this kind of thinking is problematic, including that we always hope to introduce foreign ready-made talents with their own projects. They are not ready to raise fish, but to catch a fish

compared with relatively large instruments and equipment, the investment required in the production process of sensors is generally not very large, so it is more suitable for small enterprises to invest. In this regard, China should have advantages. However, if we consider from another aspect, this is also a disadvantage

a characteristic of the sensor industry is that the sensor itself has high technical content, but the price of a single sensor is generally not high. One result of this feature is that although the technical added value of sensors is high, it is difficult to form a considerable output value simply relying on sensors

according to the metaphor of Professor Dong Yonggui, the sensor is a bit like the drug introduction in traditional Chinese medicine. Its own function is very important, but the real formation of scale still needs to rely on the whole drug. Many foreign sensor companies will soon develop relevant measuring instruments once they have a breakthrough in a certain sensor

moreover, under China's patent protection mechanism, the key technologies painstakingly developed in sensors often present a kind of know-how. After being copied, it is difficult to explain clearly, and enterprises can't afford to file a lawsuit. Although there are also MEMS sensor enterprises in China, they are all commissioned processing, and if not, they will be done by the processing enterprises themselves. There are great problems in the current enterprise innovation system

in 2012, a senior in the field of domestic sensors said at a meeting that the reason why the development of China's sensor industry is not good is the lack of leaders who can give lectures to the State Council. The research and development in this field takes a long time and is not significant enough. It is a small thing in itself, and the physical phenomenon on which it is based was discovered decades or hundreds of years ago

the scholar pointed out that this kind of research is actually very hard. For example, there is an acceleration sensor used for seismic wave measurement in the oil industry, which is based on the principle proposed by the Soviet Union decades ago, but it was not until the expert came to the United States after the collapse of the Soviet Union that the product was applied

the more we need to accumulate and grow widely, the greater the gap between us. Dong Yonggui believes that the gap has a trend of further widening

will the next five years be the life and death line of domestic sensors

signal amplification of this chipset

in recent years, the overall development scale of China's sensor industry has gradually expanded, and it has been significantly applied in the automotive industry, including sensor applications in automotive tires, airbag, chassis system, engine operation management system, exhaust gas and air quality control system, ABS Sensor application and demand in vehicle driving safety system, sensor application and demand in vehicle anti-theft system, sensor application and demand in engine combustion control system, sensor application and demand in vehicle positioning system, sensor application and demand in other vehicle systems. In addition, Chinese sensors also have new applications in other fields, such as industrial control, environmental protection, facility agriculture, multimedia image and other related sensor applications

Research Report on prediction and investment strategy of China's sensor industry in shows that although China's sensor industry has developed rapidly, there are also some adverse factors. For example, in terms of product technology, the industrial foundation is weak, science and technology are divorced from production, the level of product technology is low, the product category is lack, and the enterprise's product research and development ability is weak. However, on the other hand, the country continues to formulate strategies and policies conducive to the development of the sensor industry, the rapid development of the whole machine system market throughout the year, and the continuous promotion of emerging technologies have also become favorable factors for the development of sensing

there are about 40 countries in the world engaged in the research and production of sensors, with more than 5000 research and development and production units and more than 20000 products. There are 1688 enterprises and institutions engaged in the research, production and application of sensors in China, of which more than 50 are engaged in the research and production of MEMS, but the scale and application fields are small

in the international market, enterprises from Germany, Japan, the United States, Russia and other old industrial countries dominate the sensor market. Many manufacturers have achieved large-scale production, and some enterprises have an annual production capacity of tens of millions or even hundreds of millions. In contrast, the application scope of sensors in China is relatively narrow, and more applications still remain in basic application fields such as industrial measurement and control. Depending on this, the competition in China's sensor market is very fierce

the next five years will be five years of steady and rapid development of China's sensor market. Under the annual growth momentum of more than 30%, the scale of China's sensor market is expected to reach more than 120billion yuan in 2014. At present, from the perspective of the whole field of gas sensors, although the technology is stable, the threshold is very low. The future direction can only be advanced. The development of IOT will greatly promote the development of sensor field, which will have great applications in energy, intelligent sensing, security monitoring, environmental protection and other fields. It is estimated that by 2020, the scale of gas sensor industry will reach more than 60billion yuan, and the localization rate will reach more than 70%

including sensors based on MEMS technology, gas sensors for environmental monitoring equipment, flow sensors, humidity sensors, etc. In addition, the 12th Five Year Plan of IOT also mentioned the development of micro and intelligent sensors, wireless sensor networks, etc. in key projects. Sensors also have new applications in other fields, such as industrial control, environmental protection, facility agriculture, multimedia image and other related sensor applications
