Piezoelectric-Based Low-Power Wind Generator Design and Testing

Abstract

The main purpose of this paper is to show, design and test a new piezoelectric-based low-power generator to generate cheap and clean energy. The presented generator can be evaluated as an experimental renewable energy producing system. Obtained results show that presented generator systems can be constructed on a large scale for usable energy production. Power production capacity of presented generator can be increased with technical and physical improvements. Simple structure and cheapness are the most important features of presented generator. This generator includes an unbalanced propeller and a piezoelectric material equipped board. This unbalanced propeller generates mechanical vibration by the variation of wind speed conditions. These vibrations are transferred to a piezoelectric material equipped board. The piezoelectric material equipped board converts these vibrations into electrical power. Some experimental data were collected under different wind speeds and different external load resistances to evaluate presented generator. Changes in output power are shown with graphics related with dependent wind speed and external load resistors.
