Overall analysis of sensor manufacturing industry

Core reminder: Optical fiber sensors have been widely used in the fields of national defense, electric power, petroleum, construction, medicine, etc. With the development of Internet of Things technology, optical fiber sensors will play a more important role in the Internet of Things together with wireless sensing technology. The global optical fiber sensor market is developing rapidly. American technology is advanced. American optical fiber sensor research started early, and optical fiber sensor technology is advanced in the world. Data shows that the size of the US optical fiber sensor market was US$235 million in 2007. Since then, it has grown at a compound annual growth rate of 30%, and is expected to reach US$1.6 billion in 2014. From the perspective of the global market, the global optical fiber

The rapid development of the global optical fiber sensor market, American technology^ advanced

The research on optical fiber sensors in the United States started early, and optical fiber sensing technology is the most advanced in the world. Data shows that the size of the US optical fiber sensor market was US$235 million in 2007. Since then, it has grown at a compound annual growth rate of 30%, and is expected to reach US$1.6 billion in 2014.

From the perspective of the global market, the global optical fiber sensor market in 2013 was US$1.89 billion. It is expected that the market will grow at an average annual growth rate of 18% from 2014 to 2018, and the market size will reach US$4.33 billion in 2018.

The domestic optical fiber sensor market is in its infancy, but there is broad room for development

The sensor industry report issued by the Prospective Industry Research Institute pointed out that the current optical fiber sensing industry in my country is in its infancy and the market size is not large. However, many domestic industries have also begun to widely use optical fiber sensors. For example, a large number of optical fiber sensors will be used in fields such as oil and gas, aerospace and biomedicine; another example, optical fiber sensors can be embedded in concrete, carbon fiber reinforced plastics and various composite materials. It is used to test stress relaxation, construction stress and dynamic load stress, so as to evaluate the structural performance of the bridge in the short-term construction phase and long-term operating state. Under the influence of policy promotion and scale effect, the market space of optical fiber sensors is becoming wider and wider.

Foresight Industry Research Institute Sensor Industry Research Group also pointed out that by the end of 2013, there were 263 sensor manufacturers in China with a scale of 20 million yuan or more. However, the overall quality of the industry is uneven. The number of sensor companies above designated size is dominated by small companies, accounting for nearly 70%. At the same time, most companies focus on the production of low-end products, with price competition as the mainstay. The competition is fierce, while high-end products are concentrated among leading companies and foreign-funded companies.

The award-winning Zhejiang Institute of Metrology and Measurement of "White Light Interference System in the Application of Optical Fiber Sensor Characteristic Measurement" project has developed a set of devices that can perform laboratory and online measurement of fiber grating sensors to achieve the uniformity and uniformity of fiber gratings. The measurement of the performance of the demodulation system and the ability of online measurement. In the application field of optical fiber sensors, the system also provides metrological verification services for optical fiber sensor systems used in large-scale engineering projects. The success of this research project will help improve the high-end technology level of the domestic sensor industry and enhance the competitiveness of domestic enterprises in the high-end and emerging sensor product markets such as optical fiber sensors.
