Multi-layered transducer array and method for bonding and isolating
First Claim
1. In a multi-layered transducer array, an improvement comprising at least one element including at least two layers of transducer material;
- at least one kerf extending through a first of the at least two layers and into a second of the at least two layers within each element of the at least one element, the kerf electrically isolating two electrodes of different polarities associated with the two layers of each element of the at least one element,wherein each element of the at least one element comprises a single mechanical element structure.

Abstract
Multiple layer elements for a transducer array are provided. Each element comprises two or more layers of transducer material. Various of the elements include one or more of: (1) multiple-layer, multiple-dimensional arrays where the layers are polymericly bonded together and electrically connected through asperity contact, (2) multiple layer array of elements where air or gas separates at least two elements, (3) an even number of layers where each layer is electrically connected through asperity contact, (4) multiple-layers where each layer comprises transducer material and electrodes in a substantially same configuration, and (5) electrically isolating electrodes on layers by kerfing or cutting after bonding the layers together.
