China's first mobile phone sensor chip will change the import history [full text]

Recently, China's first commercial MEMS gyroscope with independent intellectual property rights was born in Shanghai. This is the first mobile phone sensor chip in China and will change the history of China's mobile MEMS gyroscope completely imported from abroad.

Shen Di Semiconductor Co., Ltd., a company that developed MEMS gyroscopes, is a company founded by a returnee. It was founded in 2008 and was established by a famous venture capital company.

The company’s CEO, Zou Bo, said that the first gyro product released by Shenzhen Shendi Semiconductor was named “moving core”, marking the birth of the first commercial MEMS gyroscope with Chinese independent intellectual property rights.

It is reported that the gyroscope is a device for sensing and maintaining the direction. It is the main basis for judging azimuth in aviation, navigation, and space navigation systems, and is widely used in automobile safety, model airplanes, and telescopes. Compared with ordinary chips, it also has a sensing function in addition to the calculation function. Through the built-in gyro sensor, you can sense the movement of the outside world and respond accordingly.

"For example, when the phone screen is face down, the phone will automatically be set to silent mode; or the phone will be turned three times, the phone automatically locks," Zou Bo said.

According to Zou Bo introduction, the application of gyroscopes in the field of mobile phones has been very extensive, like the digital compass in the iPhone is one of its six major functions. At present, there are only three MEMS chip designs in the world. Besides Shen Di, the other two are American Invensense and European STMicroelectronics.

At present, the concept of the Internet of Things is hot and is being raised to the national strategic level in China. This is an opportunity for Shendi. From the concept of simple interpretation, the Internet of Things is the sensor plus the Internet, and the sensor chip is the core components of the Internet of Things. The gyroscope itself is a kind of micro-electromechanical sensor. The successful development of home-made MEMS gyroscope products will bring huge business opportunities to the vast number of Chinese related markets, and will also greatly increase China’s international competitiveness in MEMS (micro-electromechanical) sensors. Influence.

Zou Bo also said that in addition to the consumer electronics market, gyroscopes have another huge market: automotive safety and automotive electronics market. In addition, he revealed that SMIC will also create new applications for the Internet of Things (positioning tracking and remote control of logistics systems) and anti-terrorism.
