    Patent number: 6489706
    Abstract: 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.
