Original Abstract Submitted
A transducer device is described that includes a substrate having an opening, and a cantilever device having a first end on the substrate and a second end suspended over the opening. In at least one example, the cantilever device includes a first piezoelectric layer having a first surface, the first piezoelectric layer having a first poling direction. The cantilever device further includes a second piezoelectric layer having a second surface opposing the first surface, the second piezoelectric layer having a second poling direction, the second poling direction being different from the first poling direction. The cantilever device further includes a first electrode on the first surface, and a second electrode on the second surface.
