How does a mems accelerometer work
WebMEMS accelerometers convert mechanical vibrations into an electrical voltage or a digital value. The MEMS sensor is made up of movable and fixed silicon elements that are interlocked to form a capacitor as shown in Figure 1a. Mechanical movement causes the movable element to shift toward the fixed element.
