MEMS Technology and Working Principle of Accelerometers

05/13 · MEMS technology is used in many applications such as accelerometer, gyroscope, and pressure sensors. Accelerometers are extensively used in the wearables, automotive airbag sensors, etc. They measure the rapid deceleration of a vehicle upon hitting an object by sensing a change in voltage. Based on the rate of this voltage change, the circuitry

Accelerometer - Applications, Types and Working Principle - VEDANTU

The main working principle of an accelerometer is that it converts mechanical energy into electrical energy. When a mass is kept on the sensor which is actually just like a spring it starts moving down. Since it is moving down it starts experiencing acceleration.
