Abstract

The paper deals with a novel vibrating energy harvester consisting of a cantilever beam with a spherical inertial mass attached on its free end. The vibration amplitudes of the cantilever are limited by static elastic membranes against which the sphere impacts. Two piezoelectric layers disposed on both sides of the cantilever convert the mechanical energy of the vibrations and of the impacts into electrical energy. Each of the two membranes convert additionally impact energy into electrical one with the help of two piezoelectric layers which are deposited on its top and bottom sides. A model of energy harvester is created and some solutions are presented and analyzed.
