For example, the Institute of Microsystems and Sensing Technology of the Chinese Academy of Sciences has cooperated with domestic and foreign enterprises to carry out a series of sensor technology research and development projects and achieved a number of important results. In addition, China has also established a number of national-level sensor engineering technology research centers and laboratories to promote the transformation and application of sensor technology.

4. Market opportunities: China is one of the world’s largest manufacturing bases and consumer markets, with a huge demand for sensors. With the rapid development of China’s intelligent manufacturing industry, the demand for high-precision and high-reliability sensors has greatly increased, promoting the progress and innovation of sensor technology. At the same time, China’s applications in smart cities, Internet of Things, intelligent transportation and other fields also provide a broad market space for the development of sensor technology.

5. International cooperation and exchanges: China and other countries around the world have carried out extensive international cooperation and exchanges in the field of sensor technology. For example, the Chinese Academy of Sciences-Austria cooperation project: high-performance nanomaterials and devices (including sensors and detectors), precise detection and surface functional modification, and key technology research on safe and reliable wireless sensor networks for smart factories, jointly promoting the research and development of sensor technology and Innovation. At the same time, China also actively participates in the formulation of international standards and international sensor technology conferences and other activities, continuously improving its status and influence in the international sensor field.

What development difficulties does China’s industrial sensors face? How should sensor companies respond?

Compared with ordinary sensors, industrial sensors have higher requirements in terms of function, accuracy, stability, and environmental adaptability. However, the development time of industrial sensors in China is relatively short, and there is still a large gap in technical level, especially in core technologies. I think the current development difficulties faced by China’s industrial sensors are mainly concentrated in the following four aspects:

1. The technical level is not high: Compared with some leading foreign sensor technology companies, the technical level of China’s industrial sensors still lags behind, especially in core technologies. There is a large technical gap with foreign sensor manufacturers, resulting in our industrial High-end application scenarios such as the field of electronics and new energy vehicles still rely heavily on foreign sensor manufacturers, making it impossible to achieve true domestic substitution.

2. Insufficient innovation capabilities: The sensor industry needs continuous technological innovation, but some Chinese sensor companies face challenges in innovation capabilities and lack core technologies and innovative results with independent intellectual property rights, resulting in serious product homogeneity and insufficient market competitiveness. Unable to quickly keep up with changes in market demand.

3. Product standardization and quality control: Due to the wide variety of sensor products, inconsistent standards, and uneven quality, there are cases where the quality of some products does not meet standards, which affects the reputation and development of the entire industry.

4. Fierce market competition: The market competition in the sensor industry is fierce. There are many competitors from home and abroad. In particular, leading foreign companies have obvious technological and brand advantages, which has intensified the market competition pressure on Chinese sensor companies.

Facing higher requirements for industrial sensors, how should our Chinese sensor companies respond and seize the opportunities of the times?

1. Strengthen technology research and development: Increase investment in research and development of sensor technology, cultivate and introduce high-level research and development talents, establish a research and development team, and cooperate with universities and scientific research institutions to carry out scientific research projects to accelerate breakthroughs and innovations in core technologies. In terms of core materials, chip manufacturing processes, advanced packaging technology, automated testing equipment, etc., we benchmark against international sensor manufacturers to truly improve the measurement accuracy, reliability, and consistency of our products and achieve true domestic substitution.

2. Optimize product structure: At present, domestic sensor products are highly homogenized, with almost overlapping technical specifications and application scenarios. Instead of trying to improve product competitiveness, sensor manufacturers are desperately trying to “roll up” costs and rely on low-price strategies to seize market share, resulting in The sales profits of some sensor manufacturers have continued to decline, and they have even suffered losses. They lack funds to invest in the research and development of new products and technologies, and have fallen into a long-term vicious cycle. We hereby call on domestic peers to optimize product structure based on market demand and technological trends, launch high-performance, high-quality products that meet market demand, and strengthen differentiation capabilities.

3. Strengthen standardization and quality control: As the most advanced signal sensing device, sensors’ core technical indicators are the measurement accuracy, reliability and consistency of the product. Some domestic sensor manufacturers are unilaterally pursuing production costs and production efficiency. They do not strictly control product raw materials in the manufacturing process, and even deliberately relax product inspection and testing standards. As a result, some sensors obviously fail to meet customer application requirements, and there are many problems on the client side. Quality problems have seriously affected the brand reputation and product impression of domestic sensor manufacturers. It is recommended to establish a complete product standardization system and quality management system, produce in strict accordance with standard requirements, strengthen the control of raw materials, production processes and product quality, and improve product quality and market competitiveness.

4. Expand market channels: Actively expand domestic and foreign market channels, establish a sound sales network and channel system, strengthen cooperation and communication with customers, and increase product market share and brand influence. At the same time, we strengthen market research, timely grasp market trends and customer needs, and provide reference for product development and market promotion.
