Title:
ピエゾセラミック多層アクチュエータ
Document Type and Number:
Japanese Patent JP5232167
Kind Code:
B2
Abstract:
In a piezoelectric multilayer actuator (1) having micromechanical relief zones (30) and an insulation layer (40) as well as in a method for producing said actuator, as a result of the micromechanical relief zones (30), poling cracks are concentrated in these relief regions (30). This makes it possible to provide the sections I, II, III of the multilayer actuator (1) with an insulation layer (40) which only has an extension behavior similar to the multilayer actuator (1) without poling cracks.
