MEMS Pressure and Acceleration Sensors for Automotive Applications

This paper reviews MEMS product applications in a very demanding automotive environment. Our particular interest is in the MEMS inertial and pressure sensors. Specifics of transducer manufacturing technologies will be explained in details. Also advantages and disadvantages of piezoresistive versus capacitive sensing phenomena will be discussed. Finally, main aspects of the packaging effects on the final device parameters and performance are considered too.
