Title: Shaped multilayer ceramic transducers and method for making the same

Abstract: A shape formed multi-laminate transducer which conforms to nonlinear dependent shaped geometries and the shape forming process for producing the nonlinear dependent shaped multilaminate transducer is presented. The shape forming process includes the cutting of the tape cast material to a predetermined two-dimensional shape and then pressing the cut material to form the desired three-dimensional nonlinear dependent shape. After shape forming, the sample is sintered, metalized, poled, and made into an acoustical device such as a transducer. The production of such a device by using tape cast material allows designers to easily vary the shape of the product as well as to be able to vary the properties within simply by exploiting the lamination method associated with tape casting. As such, a designer is able to design and manufacture a transducer optimized to meet the requirements of a particular application.
