WebSep 14, 2024 · Capacitive MEMS microphones work by measuring the capacitance between a flexible micro-scale membrane and a fixed backplate. Changes in air pressure created by sound waves cause the membrane to move. The backplate is perforated to let the air flow through it and is designed to remain rigid since the air can pass through its perforations. WebMicro-electromechanical system (MEMS)-based acoustic transducers are also known as microphones. The membrane materials on MEMS microphones are metal, polysilicon, silicon, and silicon nitride. The existing technology and materials used for the microphones involve expensive materials and complex process steps.
