Zusammenfassung:In a method for the production of a gradient encapsulation layer on a piezoelectric actuator , based on this gradient encapsulation layer , the piezoelectric actuator does not require an additional housing-like enveloping structure in order to be protected externally. The gradient encapsulation layer is produced by cold gas spraying of particles having different material properties.
