Application of MEMS sensors in the automotive sector
With the development of MEMS applications of electronic technology more widely, from the earliest industrial, military and aerospace applications to the general consumer market.
Military and aviation belong to the so-called high-value MEMS applications, but these two areas amount is too small, also about forty million dollars a year room for growth is limited. MEMS devices on the value of medical electronics is not bad, its average selling price is much higher than other MEMS sensor field comparable. Overall, operating income a year of high-value MEMS industry will reach $ 300 million.
But the most widely used as part of the automotive electronics industry and consumer electronics applications market, these two areas account for over 60% MEMS sensor market.
Automotive MEMS Sensors:
automotive electronics industry is considered to be the climax of the first wave of applications of MEMS sensors promoters, MEMS sensors in automotive applications, the rapid development mainly to benefit from governments launched a comprehensive vehicle safety regulations (such as the requirement that all cars include TPMS systems) and automotive trends wisdom. Global average car contains 10 sensors, in the premium, the use of from about 25 to 40 of the MEMS sensor, the better the car, the more used in MEMS, a car alone more than 70 BMW740i MEMS.
MEMS sensor to meet the demanding automotive environment, high reliability, precision, and low cost requirements. And the application direction of the vehicle demand including antilock system (ABS), electronic stability program (ESP), electronically controlled suspension (ECS), an electric parking brake (EPB), ramp starting assistance (HAS), tire pressure monitoring (EPMS ), anti-shake engine, vehicle and the vehicle inclination measurement heartbeat detection, and so on.
