According to CCID data, the size of my country's sensor market in 2019 was 251.03 billion yuan, a year-on-year increase of 14.7%, showing a year-on-year growth trend. In recent years, the country has attached great importance to the development of China's sensor manufacturing industry, and domestic brands have begun to gradually seize the market. However, with a large number of local brands fighting price wars, quality problems such as rough production and chaotic circuit boards began to surface. Whoever can take the lead in conquering the core technology means whoever has the advantage in seizing the market.

However, high-end sensors have always been controlled by major foreign brands, and there are strict requirements for patent licensing and manufacturing. To replace domestically produced sensors, not only need to overcome one level, but also need to break through multiple ones. This shows how difficult the road to localization of sensors is. . It is not impossible to cross these thresholds. Let's take a look at the new trends in our research on the localization of high-end sensors in recent years.
