PIEZOELECTRIC ACTUATOR Russian patent published in 2024 - IPC H03H9/15 

FIELD: piezoelectric equipment.

SUBSTANCE: devices based on piezomaterials, namely piezoelectric actuators. The piezoelectric actuator includes a piezoelectric layer, on the surface of which a two-wire conductive line is installed in the form of two electrode tape coatings. The piezoelectric layer is made in the form of a solid or hollow volumetric body. The conductive line is made in the form of one or two double spirals, each of which consists of electrically unconnected two similar electrode tape coatings of a spiral type located close to each other on the inner and/or outer surface of the piezoelectric layer.

EFFECT: increase in the response efficiency of the piezoelectric actuator.
