The development status of the transducer

It is understood that the Internet of things is the network of the existing network structure in the physical world, in its growth there is a change: the cost of the sensor in rapid decline. For the Internet of things, the sensor is very important. Such as a thermostat: there is no movement, the humidity and temperature sensors, then there is no data for the application to user behavior. Over the past 10 years, the cost of the sensor in some cases, plunged by 100 times. One crash happens in the field of near infrared spectroscopy.

sensor as modern science and technology at the forefront of technology, is considered to be one of the three pillars of modern information technology, but also one of the most recognized at home and abroad with the future high technology industry development. In sensor in the spring, however, China still seems to be the public see is a feast for the semiconductor giant abroad. The personage inside course of study thinks, although China's sensor market development soon, but the local sensor technology compared with world level there is still a large gap. This gap, on the one hand, show the sensor in terms of sensory information, on the other hand, is characterized by sensor itself in the field of intelligent and networked technology lag behind. Because there is no application form enough scale, leading to domestic sensor technology is low, not only and the price is high, it is difficult to competitive in the market.

sensor is the first step of automatic detection and automatic control. The existence and development of the sensor, let objects have sensory, such as touch, taste and smell let objects become live up slowly. Nowadays, with the continuous development of the Internet of things and progress, all kinds of sensors are increasingly applied to all kinds of things, the global demand for sensors are beginning to show explosive growth.

compared to relatively large instruments and equipment, sensor of investment is needed in the production process in general is not very big, so is suitable for small business investment. In this regard, China should be an advantage. However, if consider from another aspect, it's also a weakness.

sensor industry is a characteristic of the sensor itself high technical content, but the price of single sensor is generally not high. The characteristics lead to a result, although sensor technology added value is high, but it is difficult to form a considerable rely on sensor output.

in recent years, China's overall scale sensor industry development gradually expand, significant applications in the automotive industry including sensor application in automobile tires, airbag sensor applications of the sensor application, chassis system, engine sensor in the operation management system application, exhaust gas and air quality control system of the sensor and the sensor application demand, ABS and the sensor application demand, vehicle security system and the sensor application demand, car alarm system and the sensor application demand, engine combustion control system and requirements, car positioning system, automobile sensor application and demand system of other sensor applications and requirements. In addition, China sensor also has a new application in other fields, such as industrial control field, in the field of environmental protection, in the facility agriculture, and other relevant sensors in the field of multimedia image application.

《2014- 2018 China sensor industry forecast and investment strategy research report shows, sensor industry in China, though developing rapidly, but there are some unfavorable factors. Such as on the product technology industry foundation is weak, the chasm between science and technology and production, product technology level is low, the products lack, the enterprise product research and development ability weak. But on the other hand, countries continue to develop good sensor industry development strategy and policy, the rapid development of the whole machine system market, throughout the year of emerging technologies push also become the positive factors for the development of sensor network.

the world now there are about 40 countries engaged in the development and production of sensor, research and development, production has more than 5000 units, the product of 20000 ( $69720000) A variety of. 1688 domestic enterprises engaged in development, production and application of sensor, which is engaged in production of MEMS research and has more than 50, but the scale and application fields are small.

in the international market, Germany, Japan, the United States, Russia and other old industrial companies dominated the sensor market, many manufacturers realize the large-scale production, some enterprise's annual production capacity of tens or even hundreds of millions. Narrow the scope of application of China, by contrast, sensor, more applications remain based applications in industrial measurement and control, etc. Depend on it, sensor market competition is very fierce in China.

including sensor based on MEMS technology, environmental monitoring equipment with gas sensor, flow sensor, humidity sensor and so on. In addition, the release of 'the Internet of the 12th five-year plan', mentioned in the content of key projects to develop the micro and intelligent sensor, wireless sensor network (WSN), etc. Sensor also has a new application in other fields, such as industrial control field, in the field of environmental protection, in the facility agriculture, and other relevant sensors in the field of multimedia image application.

it is understood that the field of an emerging companies try to dramatically change the sensors of the economy. Consumer Physics partner DrorSharon said: '100 to 1000 times a thing for cheap is a cool thing. '
