Abstract
A piezoelectric microelectromechanical system microphone comprises a piezoelectric element configured to deform and generate an electrical potential responsive to impingement of sound waves on the piezoelectric microelectromechanical system microphone, a sensing electrode disposed on the piezoelectric element and configured to sense the electrical potential, and a passive membrane mechanically coupled to the surface of the piezoelectric element to increase sensitivity of the piezoelectric microelectromechanical system microphone.
