Sensors benefit the development of the IoT industry and still have challenges

According to statistics, by 2015, the overall market size of China's Internet of Things will reach 750 billion yuan. As the lowest level and most basic link of the “Pyramid” of the Internet of Things, the sensor industry will directly benefit from it.

In recent years, the domestic sensor market has continued to grow at speeds exceeding 10%. In 2010, China's sensor sales reached 90.5 billion yuan. It is predicted that the Chinese sensor market will develop steadily and rapidly over the next five years. Under the impetus of the substantial growth of the Internet of Things market, the size of China's sensor market in 2015 is expected to reach more than 120 billion yuan.

The development of the Internet of Things is inseparable from the development of sensor technology. However, at present, the development of sensor industrialization still poses no small challenge. It is reported that there are more than 1,700 enterprises engaged in the production and research and development of sensors in China. The annual output of sensors has exceeded 2.4 billion, and the sensor products have reached 10 categories, 42 subcategories and more than 6,000 varieties, showing a good development trend, but Among the enterprises, foreign-funded enterprises have obvious advantages, with the proportion of foreign-funded enterprises reaching 67%, especially Japan, the United States, South Korea, and Germany. State-owned enterprises and ethnic enterprises account for only 33%. Domestic and foreign enterprises have a wide range of comprehensive strengths, small scale, shortage of talents, and weak R&D capabilities, which make it difficult to compete with foreign companies.

More crucially, technically, domestic sensor technology is weak. First, the core technologies and basic capabilities are lacking. The core chips are heavily dependent on foreign imports. Domestic companies are significantly different from foreign companies in terms of high-precision, high-sensitivity analysis, component analysis, and high-end special applications. The second is the lack of unified standards and independent intellectual property rights in terms of design, reliability, and packaging. There have been no breakthroughs in interfaces, deep etching, high-temperature ohmic contact, highly reliable MEMS packaging, rapid testing, and high-simulation simulation technologies. Industrialization verification; Third, the product is not comprehensive enough in variety, specifications, series, etc., and there are still some differences in the measurement accuracy, temperature characteristics, response time, stability, reliability and other technical indicators, so China's sensor companies have a long way to go.

According to the latest news, the National Development and Reform Commission will invest 600 million yuan this year to support R&D, application demonstration projects and the construction of public service platforms for core technology products of the Internet of Things. In the future, the central government will further improve the fiscal system that supports the development of the Internet of Things, strengthen coordination with industrial policies and science and technology policies, and actively attract social capital to increase investment in the Internet of Things. With the guidance of the government and financial support, the industrial environment of domestic companies will become clearer and the domestic sensor market will continue to grow with sustained and stable growth.
