The hottest sensor strives to achieve the localiza

Sensors strive to achieve the goal of 30% localization by 2020

at present, the layout of China's sensor industry has basically taken shape, and some achievements have been made. It has basically complete product categories, and the medium and low-end products basically meet the market demand. The level of design, research and development and application has been improved to a certain extent. China's sensor industry has formed a complete

from technology research and development, design, production to application. "Electronic components are the foundation of the electronic information industry, and sensitive components and sensors are the foundation of IOT." Wen Xueli, chairman of the China electronic components industry association, pointed out at the "2016 sensor industry summit forum and the 2016 annual meeting of the sensitive components and sensors branch of the China electronic components industry association" held a few days ago, "but sensitive components and sensors are also 4. Broken samples are the bottleneck of China's IOT industry, and 80% of them are still dependent on imports."

looking back on the "12th Five Year Plan", China's sensitive components and sensors industry has achieved rapid development with an average annual growth rate of 20.9%. In 2015, the sales reached 54.7 billion yuan, more than 50% more than the original planning target of 36 billion yuan. As an important part of IOT sensing layer, sensors are widely used in automotive electronics, consumer electronics, biomedicine, industry, agriculture and other fields. The booming trend of IOT promotes the rapid development of sensor industry

achieve the goal of 30% localization by 2020

at present, the layout of China's sensor industry has basically taken shape, and some achievements have been made. It has basically complete product categories, and the medium and low-end products basically meet the market demand. The level of design, research and development and application has been improved to a certain extent. China's sensor industry has formed a complete industrial system from technology research and development, design, production to application, and some subdivisions have reached the world's leading level

however, in terms of the overall level, domestic sensor products are still dominated by medium and low-end products, and the technical level is relatively backward. The import of medium and high-end sensors in the Chinese market accounts for 80%, and there is a serious shortage of digital, intelligent and miniaturized products

the products of domestic enterprises are mainly concentrated in low-end pressure, temperature, strain gauge and other low value-added products. In recent years, several enterprises have begun to produce MEMS products, among which microphone products have a good momentum of development, but other products such as pressure, acceleration, gyroscope and so on are also relatively low-end products

during the 13th Five Year Plan period, under a series of favorable factors such as market demand and policy traction, the competitiveness of China's sensor industry is expected to be further improved

Gu Qun, Secretary General of China electronic components industry association, said that during the high degree of automation of the "13th five year plan" operation, China's electronic components industry (excluding printed circuit boards and batteries) will maintain a medium growth rate. In, China's first heavy machinery branch began to manufacture 12%cr ultra supercritical rotors in double vacuum since 2008, with an average growth rate of about 5%, among which hybrid integrated circuits, sensitive components and sensors The three sub industries of optical devices will maintain a high growth rate, among which the growth rate of sensitive components and sensors industry is expected to be as high as 9%

Gu Qun believes that with the growth of national enterprises, the market share of local brands continues to increase, and the localization development goal of 30% will be achieved for sensitive components and sensors by 2020 (here, the localization rate refers to the domestic sales amount of China's local electronic component manufacturers' own brand electronic component products, and the proportion in the total domestic market)

IOT application drives strong market demand

the booming demand for IOT application is a strong driving force to support the realization of the 30% localization goal. Sensor is an important part of IOT sensing layer, which undertakes the task of data acquisition and transmission, and is the basis and premise of IOT implementation. According to the data, the global IOT market is expected to reach US $11trillion by 2025, and the corresponding sensor market will also reach a market size of hundreds of billions of dollars

at present, more than a dozen sensors are used in an intelligent, hundreds of sensors may be used in a high-end car, and tens of thousands of sensors are used in a modern intelligent factory. Sensors have penetrated into all aspects of people's production and life. Jeremy Rifkin, the author of "the third industrial revolution" and "zero marginal cost society", boldly guessed that by 2030, the number of sensors applied worldwide will soar from 3.5 billion in 2013 to more than 100 trillion, and human and natural environment will be closely connected through sensors

"by playing a big role in the main joint application fields such as smart home, smart lighting, automotive electronics, smart medicine, smart agriculture, building structural health monitoring," said sunkunquan, executive vice president of Murata China. "Sensors will create a real intelligent life for people."

take heart rate detection for example. Murata's innovative modular scheme combines acceleration MEMS sensors, signal processing and wireless modules, which can measure the cardiac impulse scanning signal of patients lying in bed without contact. It can not only separate the patient's motion signal from the motion signal of the sickbed, detect the patient's swing, overturn and static state, but also monitor the sleep quality, monitor the heart rate and breathing of the static patient. In this way, if the equipment with this sensor is installed on the hospital bed, the medical staff can remotely monitor the real-time situation of patients. Similarly, it is also very suitable for the elderly living alone and nursing homes

Jia Yongping, marketing director of Greater China of Sensata, is very optimistic about the growing automotive sensor application market. The global automotive sensor market demand will reach US $25.3 billion in 2020, of which China is one of the three largest automotive sensor markets in the world, and will reach US $5.5 billion in 2020 with an average annual growth rate of 8.9%

Jia Yongping believes that driven by the demand for more energy-saving, cleaner and safer, the assembly rate of many advanced systems in vehicles, such as sensor controlled air conditioning systems, electronic stability control systems, common rail systems, diesel aftertreatment systems, tire pressure monitoring systems, will continue to increase when another oil port is connected to the oil return pipe, and there are a large number of sensor applications in these systems

sensitive components and sensors even have broad application prospects in the color TV industry. Chen Hezhi, the factory director of TCL trump color TV Chengdu Co., Ltd., said that in addition to key indicators such as size, clarity and display technology, the biggest selling points of current TVs are interconnection and intelligence. Based on this, sensitive devices will have great potential in the future television industry

first is light sensing. A sensor sensing the change of ambient light is set on the TV shell, which can automatically adjust the brightness of the TV according to the change of ambient light, so as to achieve the function of power saving and eye protection

secondly, Hall sensor is used to control the on-off of projection TV. The specific principle is that according to the Hall effect, the potential at both ends of the energized conductor changes under the action of the magnetic field, so as to control the conduction and cut-off of the triode, and then give the motherboard a start-up or shutdown signal

thirdly, the temperature sensor is used to control the heat dissipation of the projection TV optical machine. When the sensor detects a high temperature, it informs the CPU to output a signal to the cooling fan to increase its speed. When the temperature is slightly low, the CPU outputs a control signal to let the cooling fan run at a low speed, so as to achieve the purpose of energy saving and noise reduction

finally, the TV is controlled by gestures. At present, the output of gesture sensor based on electric field has been a perfect human-computer interaction solution. Designers can easily integrate 2D multi touch and 3D gesture recognition functions into their display applications. (according to China Electronic News)
