ST MEMS gyroscopes help mobile phones achieve innovative somatosensory control

The somatosensory control mechanism was introduced in the latest iPhone 4 mobile phone equipped with a MEMS 3-axis gyroscope for the first time. This device can accurately simulate the current spatial position and motion sensing of the mobile phone with gravity sensing, thereby realizing accurate control of the game. Undoubtedly, the appearance of this stunning feature on mobile phones will attract more eyeballs for the iPhone 4.

In recent years, the penetration of MEMS in the consumer electronics market is constantly improving. In addition to the use of low-g accelerometers to implement motion-controlled user interfaces and enhanced protection systems in game controllers, mobile phones, laptops, and white goods, the use of MEMS gyroscopes is becoming more and more widespread. Wave's rapid growth in innovative applications.

Since the launch of the first MEMS product in 2009, ST has released 30 high-performance gyroscope products as a leading supplier of MEMS sensors in the consumer electronics and mobile phone markets. Zhang Yingna, head of ST Greater China, said at the IIC China conference held recently that MEMS gyroscopes will become the company’s second largest business growth point in the future. In the next 2 to 3 years, this area will be expected to achieve 20% growth. . Consumers will be able to enjoy the use of a variety of MEMS products. "ST's MEMS products account for 50% of the market in consumer electronics and 20% in the automotive electronics market."

Zhang Yingna believes that the MEMS products will be seen in many applications (such as remote controls and games) in which tablets, game controllers and triple play are integrated. In addition, MEMS are also used in some portable medical devices, such as devices that prevent snoring. However, she also pointed out that MTK platform is less likely to adopt MEMS products because of the closed development system.

"With the increasing demand for multiple sensors from consumer electronics, integrating several sensors in one module will be a future trend. For example, a G-sensor and an accelerometer, or a gravity sensor, can be used. Integrated with the gyroscope to achieve richer functions. Integrating the MCU and the sensor is also a good development direction. The MCU can be used to implement processing functions.” Zhang Yingna said, “Gyroscope technology compared to gravity sensors The threshold is higher. The integrated route helps improve product performance and reduce costs.”

The L3G4200D introduced by ST last year is a 3-axis digital gyroscope that uses a sensing structure to detect three orthogonal axial movements. Since the three axes share a sensing structure, the signal interference between the axes can be eliminated and the output signal can be prevented from being affected by the interference signals. In addition, this innovative product architecture allows the sensor and ASIC interface to be integrated in a 4 x 4 x 1mm ultra-small package to address the space limitations of current and future consumer electronics applications.
