MEMS accelerometers are microelectromechanical systems that measure acceleration. They are tiny devices that can detect static force like gravity, as well as dynamic forces from movement and vibration. The core of a MEMS accelerometer typically consists of a proof mass suspended by springs. When the device experiences acceleration, the proof mass moves relative to its casing. This displacement is then converted into an electrical signal. Common sensing mechanisms include capacitive, piezoresistive, and piezoelectric methods. Capacitive sensors detect the change in capacitance between the proof mass and fixed electrodes as the proof mass moves. Piezoresistive sensors utilize materials whose electrical resistance changes with applied strain. Piezoelectric sensors generate a voltage when the proof mass applies pressure to a piezoelectric material. MEMS accelerometers are widely used in a variety of applications. These include smartphones for screen orientation sensing and gaming, automotive safety systems like airbags and electronic stability control, navigation systems, industrial automation for vibration monitoring, and consumer electronics for motion detection. Their small size, low power consumption, and cost-effectiveness have made them ubiquitous in modern technology.
