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. WebApr 4, 2024 · The MEMS accelerometer design considered for the implementation of the proposed deep-neural-network-based optimization methodology is shown in Figure 1. The MEMS accelerometer design allows to measure input acceleration in two in-plane axes, thus making it a 2-DoF design.
