Anisotropy of electromechanical parameters of a single-layer composite of the piezoceramic - polymer system

Abstract

Samples of a single-layer composite of a piezoceramic-polymer system were investigated. The basic electromechanical parameters of the experimental samples were measured. Anisotropy of the electromechanical coupling coefficients and mechanical Q factors for thickness and radial modes of oscillations, as well as the corresponding piezoelectric moduli, was revealed.
