Abstract

See full text

An ultrasonic transducer device including a substrate, an edge support structure connected to the substrate, and a membrane connected to the edge support structure such that a cavity is defined between the membrane and the substrate, the membrane configured to allow movement at ultrasonic frequencies. The membrane includes a structural layer, a piezoelectric layer having a first surface and a second surface, a first electrode placed on the first surface of the piezoelectric layer, wherein the first electrode is located at the center of the membrane, a second electrode placed on the first surface of the piezoelectric layer, wherein the second electrode is a patterned electrode comprising more than one electrode components that are electrically coupled, and a third electrode coupled to the second surface of the piezoelectric layer and electrically coupled to ground.
