According to iSuppli, global shipments of automotive Microelectromechanical Systems (MEMS) sensors are expected to nearly double from 2006 to 2012. iSuppli forecasts worldwide automotive MEMS sensor shipments will grow to 935.7 million units in 2012, rising at a Compound Annual Growth Rate (CAGR) of 12% from 474.2 million units in 2006. Global auto MEMS sensor revenue will increase to $2.1 billion in 2012, increasing at a CAGR of 8% from $1.3 billion in 2006.
The automotive MEMS sensor segment consists of 26 established and emerging applications in chassis, power train and body electronics. Major product areas for automotive MEMS are inertial sensors, pressure sensors, flow sensors, infrared sensors and emerging sensors. These tiny devices perform a variety of safety, control and environmental functions, from airbag collision detection, to tire pressure monitoring, to engine management.
MEMS use many processes common in the silicon IC industry, but have either small moving parts or regions that sense different physical parameters.
Shipments of MEMS pressure sensors for Tire Pressure Monitoring Systems (TPMSs) are expected to reach 179 million units in 2012, up from 43.1 million in 2006. Shipments of MEMS inertial and pressure sensors used in ESC systems will increase to 158 million units in 2012, increasing at a Compound Annual Growth Rate (CAGR) of 17 percent from 61.6 million units in 2006.
