The automobile’s safety air bag has applied the MEMS accelerometer early in the 1990s, and the second application wave was set up in the flowing ten years. The second generation of technique has replaced the first generation, and become the mainstream. According to statistics, the scale of automotive sensor market was 2.5 billion in the year of 2009. The growth rate of the sensor market had reached nine percent from 2004 to 2009. With the development of the technology, the third application wave is coming. More and more MEMS accelerometers and gyroscopes are emerging in the new technical field.
Nowadays, the challenges for the MEMS are mainly from the system level design, test, analysis, the development of embedded software and the power management. The elements, which are needed to optimize the MEMS, are becoming the challenge of the technical engineer. The MEMS sensors need to be optimized further in the future ten years, which aims to provide the more powerful functions and reduce the cost. This also benefit to the development of the MEMS motion detection.
The MEMS sensor is suitable for the automotive controlling systemï¼which is widely applied in the engine control system and body control system in the recent years. The application of the accelerated sensor includes the electric stability control, air bag monitoring, GPS navigation and safety system.
In order to win in the third application wave, the supplier should not only to concern the basic motion detection and other new functions, but also can deal with more demands and challenges. The new MEMS sensor should keep the high sensitivity in all the condition. The designer should provide the worthy solution to improve the performance of the system, thus the automation is implemented, and the cost is reduced. All the efforts of people must drive the MEMS technique to develop in the future years. The related integrated circuit is CAT5116RIMSOP.
