MEMS sensors are an industrial opportunity in China：

"This industry can't be done in a lifetime. This is an industrial opportunity for China." When it comes to MEMS sensors, Li Gang, the founder and chairman of Minxin, has obviously more words. From university to now, Li Gang has done one thing - research and development of MEMS sensors. He's glad he's picked an interesting industry. An industry that can contribute to the country and society.

After more than 20 years of hard work, Li Gang now has more confidence in China's MEMS industry. "Whether it is consumer electronics, automotive electronics, or industrial and medical. More and more downstream places have put forward new demands for MEMS sensors. This is the development opportunity for MEMS sensors." Li Gang told reporters, given the particularity of the production process. In particular, MEMS sensors require design companies to master manufacturing and packaging processes. Therefore, those MEMS sensor companies with deep accumulation will have a broader development path, that is, the platform has a "multiplier effect".

Intelligent sensors usher in new development：

"Some time ago, Huawei's pig-raising news was on the screen. Did you know that sensors are also needed for pig-raising?" Referring to the new application of sensors, Li Gang gave reporters an example, "Pig farms need to measure ammonia, carbon dioxide, Hydrogen sulfide, as well as temperature and humidity, all require corresponding gas sensors.”

According to data, the number of sensors used in smartphones has risen to nearly 20. In the autonomous driving module, only 6 sensors are used for L2 autonomous driving. L3 autonomous driving will increase to 13 sensors. L5 autonomous driving will use more than 30 sensors... From smartphones (smart terminals) to smart cars and biomedicine, sensors have already shown their talents.

As long as it is a field that needs to be perceived, sensors are required. In the next 5 to 10 years, the Internet of Things will be the technology that will have the greatest impact on the development of China's economy and GDP. Sensors, especially MEMS sensors, are the foundation and core of the IoT perception layer. It will usher in applications and growth beyond people's imagination in thousands of industries.

MEMS sensors usher in new opportunities：

MEMS sensors are an industrial opportunity in China. For MEMS sensor companies and practitioners, the more important industrial logic than the continuously growing downstream market is that China's MEMS sensor industry has caught up with two major opportunities. First, the transfer of industries from Europe and the United States to China makes it easier for China to quickly catch up with the world's advanced level. The second is to catch up with the transformation and upgrading of the domestic manufacturing industry, and new applications will bring acceleration to the development of the MEMS industry.

How big is the industry opportunity for MEMS sensors? According to data, the market size of the global MEMS industry has reached US$11.5 billion in 2019. The French third-party agency Yole predicts that by 2023, the global MEMS market will exceed $30 billion. China has become the fastest growing region in the global MEMS market.

Under such a big opportunity in the industry, new products and new applications will emerge one after another. In turn, the sensor market will grow faster. A typical case is that due to the new crown pneumonia epidemic, thermopile infrared sensors ushered in new application scenarios. The surge in demand has also given the public a better understanding of sensors.

More new needs than imagined：

Too many fields are still waiting to be disrupted by MEMS sensors. For example, electronic cigarettes can also be added with pressure sensors, and thermopile sensors may also be applied to TWS headphones. The premise is that the sensor is light, thin, short and low power consumption.

Under the opportunity of the continuous development of MEMS, Jingxun's MEMS ammonia sensor was born. The micro-hot plate is made by MEMS process, using metal oxide semiconductor material as gas sensing material. The MEMS ammonia sensor uses a simple circuit to convert the change in conductivity into an output signal corresponding to the concentration of ammonia gas. The ammonia gas sensor has the characteristics of small size, low power consumption, high sensitivity, fast response recovery, simple driving circuit, good stability, long life and the like. It can be widely used for ammonia gas detection in refrigerators, ammonia leakage in refrigerators, and ventilation control in agricultural breeding.

The MEMS gas sensor uses the MEMS process to fabricate a micro-hot plate on the SI base substrate. The gas-sensing material used is a metal-oxide-semiconductor material with low conductivity in clean air. The conductivity of the sensor changes when the detected gas is present in the ambient air. The higher the concentration of this gas, the higher the conductivity of the sensor. The change in conductivity can be converted into an output signal corresponding to the gas concentration using a simple circuit. The product is small in size and high in resonance frequency. Low power consumption and short response time. A high surface-to-volume ratio can improve the sensitivity of the surface sensor.
