Two Main Applications Promote MEMS Sensor Technology

Follow the development of MEMS and sensors, the MEMS sensors are used in many industries. But in generally speaking, two main application areas make it developing fast! They are automotive and consumer electronics.

In the field of consumer electronics, Nintendo has been used MEMS devices in Wii wireless game, it allows users to communicate with each other through sports and click on the screen and deal with demand on the screen. How it can do this? The principle is the movement (such as waving arms to imitate the movement of tennis racquet) turns into the game behavior on the screen. Earlier, Nintendo and ADI's ADXL330 iMEMS announced ADI accelerometer into Nintendo's Wii game console. The accelerometer helps Nintendo video games develop to a new level.

Now, most phones with MEMS accelerometers and gravity sensors to achieve the function of gyroscopes. For example, MEMS sensor is used in the iPhone. By rotating the perception of movement, iPhone can automatically change the display anyway, so that consumers are able to fit the horizontal and vertical angle to see the full page, or digital and pictures.

In automotive applications, the area used with MEMS sensors is more and more. Including airbags in automobile airbag sensors, suspension control, rolling and so on. It also includes automotive MEMS pressure sensor and automatic tire pressure monitoring system, MEMS pressure sensor suitable for any type of tire, the tire wall in the sense of laying a small piece of pressure sensitive chip, automatic measuring tire pressure, temperature, speed and other data, and the specific code used to send out. In addition, car navigation GPS signal compensation, the cylinder pressure measurements, and most of another automotive subsystem.
