MULTILAYER PIEZOELECTRIC CELL Russian patent published in 1995 - IPC

FIELD: piezoelectric transducer manufacture. SUBSTANCE: multilayer piezoelectric cell has piezodisks and current collectors. Current collector has two collecting pads connected through jumper and two lugs. Piezodisks have four flats of width equal to that of lugs. Bottom and top current collectors have two additional lugs each to lock bottom and top piezodisks. Each current collector embraces two adjacent piezodisks and its lugs are rigidly fixed together. Insulating layer is applied to inner surfaces of lugs and jumpers of current collectors. Adjacent current collectors are spaced 90 deg. apart and form unlike-polarity electrodes. EFFECT: improved design. 4 dwg
