Abstract (en)
[origin: DE19909452C1] A piezoelectric actuator (10), designed as a multilayered laminate, consists of layers of piezoelectric material (11) and metallic, conductive electric layers in between (12,13) serving as electrodes contacted alternately through common electrode paths (14,15) on the actuator casing sides and connected with these paths to supply connectors (16,17) for supplying operating voltage to the actuator.
