FIELD: piezoelectric electromechanical drives or packaged sensory components.
SUBSTANCE: proposed drive or sensory component has several piezoelectric ceramic layers. Electrode layer and electrical connector protruding outside are disposed between two layers whose surfaces are facing one another and directly abutting against one another. At least one of two piezoceramic layer surfaces facing one another is provided with groove to receive at least part of electrical connector.
EFFECT: enhanced precision under impact of high temperatures and heavy steady state and transient loads.
