Modern day microphones and audio sensors utilize MEMS acoustic membranes as a means to convert sound waves in to electrical signals with extreme precision and sensitivity. Such membranes are thin diaphragms constructed from typical silicon, polysilicon or metal material that deflect under applied pressure to create a change in electrical resistance or capacitance. MEMS microphones form an essential part of various applications spanning consumer electronics, such as smartphones and smartwatches, to industrial and medical equipment where accurate audio capture is critical. MEMS acoustic membranes can detect and quantify the slightest pressure variations due to their high sensitivity and accuracy, enabled by specific design of such components.
