Abstract

This work presents test results for usable characteristics of two-layer, bending piezoelectric converters subjected to electric field and mechanical load. A general solution has been developed, based on implementation of piezoelectric segments PBS to a bent beam. Working mechanism and conditions for strain of PBS segment were determined. Basing on the general solution, for cantilever converter (of single or two PBS segments) and converter resting on two supports of one PBS segment particular solutions were developed. The resulting analytical solutions were compared with literature data, and the developed FEM solution.
