摘要： A method is described for making a piezoelectric composite for building an acoustic transducer from two or more pieces of piezoelectric material. Each piece of material is cut to form slots or trenches having a uniform pitch spacing and material portions of uniform width such that the material portions of one piece may be received within the slots or trenches of the other. The pieces are then interdigitated and joined to make the piezoelectric composite.

摘要： A plurality of piezomaterial bodies, such as panels or slices, are merged together to form a larger piezomaterial body. For example, a 0.75×22 cm polycrystalline piezomaterial body is formed, where the distances are along lateral or footprint dimensions. The thickness of the piezomaterial body is substantially less than either of the distances along first and second lateral dimensions that define the footprint. Preferably, each piezomaterial body has a panel shape, and a plurality of panels are merged to form a large multi-panel.

摘要： A low mass in the acoustic path flex circuit that has a thin metal layer in the acoustic path area and thicker electrical traces. The low mass flex circuit allows for mass termination of the signal and ground traces with the electrodes of the piezoelectric piezoelements. Regions that are to be diced are reduced in thickness to decrease the loading on the dicing blade during fabrication.
