Piezoelectric MEMS microphones based on rib structures and single crystal PZT thin film

Abstract In this study, a controllable mass‒frequency tuning method is presented using the etching of rib structures on a single-crystal PZT membrane. The rib structures were optimized to reduce the membrane mass while maintaining the stiffness; therefore, the center frequency could be increased to...
