Abstract:
1. A process for manufacturing an actuator configured to generate power ultrasound and including a stack of alternate intermediate electrode and piezoelectric material layers, the method comprising: forming an initial stack of alternate intermediate electrode and piezoelectric material layers, each end of the stack being a piezoelectric material layer or an intermediate electrode layer; securely joining adjacent layers together; cutting the initial stack into elementary units such that, in a first elementary unit of the elementary units, each of the intermediate electrode layers has a first visible face on a first side of the first elementary unit and a second visible face on a second side of the first elementary unit; and connecting the intermediate electrode layers, including a first group and a second group, of the first elementary unit together via a first connection electrode and a second connection electrode, wherein the first connection electrode connects the first visible face of each of the first group of the intermediate electrode layers without contacting the first visible face of each of the second group of the intermediate electrode layers.
