ABSTRACT:
Multiple layer elements for a transducer array are provided. Each element comprises two or more layers of transducer material. Various of the elements are manufactured by one or more of: (1) stacking to form a multiple-layer, multiple-dimensional array where the layers are polymericly bonded and electrically connected through asperity contact, (2) using air or gas to separate at least two elements, (3) stacking an even number of layers where each layer is electrically connected through asperity contact, (4) using 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.
