<p>Electrodes (111) extend over one or more sub-regions of the interior of the rectangle, and lead to reinforced pads (111a) or lands (111b) extending at the edge of the device. The electrodes are arranged in a pattern to contact a piezoelectric element along a broadly turning path, which crosses the full length. Frame members (120) are positioned about the perimeter of sheet (110) and at least one piezoelectric plat element (112) is situated in the central region so that it is contacted by the electrodes (111). The frame members serve as edge binding, so that the thin laminations do not extend to the edge, and they also function as thickness spacers for the hot-press assembly operation described further below, and as position-markers which define the location of piezo plates that are inserted during the initial stages of assembling the laminated package.</p> |
