Abstract

The paper analyzes the influence of the characteristics of proof mass on the output characteristics of cantilever-type piezoelectric generators (PEGs) with bimorph elements by using finite element modeling (FEM) in the ANSYS software. This investigation studies the effects of the geometric dimensions of proof mass and the place of its attachment. Symmetrical and asymmetrical cases of mass placement are also studied. The problems of the evaluation of influence of PEG’s electromechanical characteristics on output parameters of the generators are considered. The results of the computations of output voltage and power of the PEGs are present.
