PIEZOELECTRIC ACTUATOR Russian patent published in 2024 - IPC H02N2/02 H10N30/50 

FIELD: electricity.

SUBSTANCE: invention relates to electromechanical converters based on piezoelectric materials, specifically to piezoelectric actuators for use in micromechanics, controlled optics, sensor equipment, acoustics, particularly in making sensors and emitters. Piezoelectric actuator includes a piezoelectric layer between two electrodes interacting through this layer of an extended double-wire current-conducting curved line with external outputs for connection to electrodes of polarizing or control voltage. Piezoelectric layer and electrodes of double-wire current-conducting line as a whole have the form of flexible electroded piezoelectric fibre, which in the form of a coil is impregnated with a liquid polymer binder and fixed by its subsequent curing with formation of a solid-state fibrous composite piezoelectric actuator.

EFFECT: higher efficiency of piezoelectric actuator.
