PROCESS FOR PRODUCING AN ACTUATOR HAVING A STACK OF ALTERNATING INTERMEDIATE ELECTRODE LAYERS AND PIEZOELECTRIC MATERIAL LAYERS

摘要

A process for producing an actuator configured to generate powerful ultrasonic waves and that includes a stack of alternating intermediate electrode layers and piezoelectric material layers. The method includes: forming an initial stack of alternating intermediate electrode layers and piezoelectric material layers, each end of the stack being a piezoelectric material layer or an intermediate electrode layer; firmly attaching adjacent layers to one another; cutting the initial stack into elementary blocks; and connecting the intermediate electrode layers together, in each elementary block.
