The market for automotive microelectromechanical systems (MEMS) is expected to reach $2.1 billion by 2012, up from $1.4 billion in 2007. Fifty to seventy sensors are deployed in the average, mid-range car for safety and environmental duties. In luxury vehicles, the MEMS content is even higher. As concerns over gas mileage, global warming, accident prevention and engine management become of higher importance to automotive consumers, the opportunity for MEMS suppliers grows simultaneously. The iSuppli automotive MEMS service tracks changes and new offerings in vehicles as well as the impact of these offerings to consumers and sales of vehicles.
