Experimental Studies of Cantilever Type PEG with Proof Mass and Active Clamping

Abstract

It is considered experimental simulation of a cantilever piezoelectric generator (PEG) with an active clamping. The generator has two types of piezoelectric elements: (i) elements located on a substrate in the form of a bimorph, and (ii) piezoelectric elements of cylindrical shape fixing the base plate. The considered PEG is a part of the energy generation system, designed to convert mechanical energy from the environment into electrical energy, followed by its accumulation. The results of the analysis of forced oscillations in the vibration excitation of the PEG base are presented. The analysis of PEG output parameters was carried out under vibration loading of PEG base.
