Abstract
Piezoelectric materials are utilized in shear mode deformation to excite longitudinal flexural bending electromechanical motion in a transducer. A single transducer stack comprising a plurality of shear mode piezoelectric material elements are arranged to create a flexural bender bar which can be used for electroacoustic applications. The transducer stack is configured such that adjacent piezoelectric elements have opposite shear mode deformation. Electrodes for positive and negative voltage excitation are applied to parallel faces of the piezoelectric elements. Application of a voltage difference between the electrodes causes the piezoelectric elements to undergo shear strain, wherein one half of the transducer stack expands into tension and the other half contracts into compression, thus inducing longitudinal flexural bending electromechanical motion. Enclosed embodiments provide support structures for utilization of piezoelectric shear mode induced longitudinal flexural bending electromechanical motion.
