Original Abstract Submitted

A piezoelectric microelectromechanical system microphone has a piezoelectric sensor layer with at least two sensing electrodes and at least one piezoelectric layer. Each piezoelectric layer can deform and generate an electrical potential responsive to impingement of sound waves on the piezoelectric layer. The sensing electrodes and the at least one piezoelectric layer form a stacked electrode structure. Each sensing electrode is disposed on or below a corresponding piezoelectric layer and senses the generated electrical potential. At least one of the sensing electrodes can include first corrugations which are configured such to release residual stress and to improve sensitivity of the microelectromechanical system microphone.
