Abstract

The natural frequencies and electrochemical coupling coefficients of three-layer (trilaminar) piezoelectric ceramic transducers were altered using membrane loads. Two types of trilaminar flexural transducers were studied: beams and disks. For both transducers, significant changes in natural frequencies as well as increases in coupling coefficients were obtained. Overall, the results demonstrate the feasibility of using membrane loads to improve the frequency agility of flexural piezo transducers.
