Proposal of a Micro Generator Piezoelectric for Portable Devices from the Energy Harvesting

Abstract

This paper presents a proposal for clean energy generation through the Piezoelectricity PZT via piezoelectric cells that convert mechanical energy through the deformation of the material into electrical energy to recharge and power portable devices. This research presents a proposal for capturing mechanical energy used daily by the entire world population and the movement of the walk, where a pressure is generated in footwear and soil, is pressure is being transformed into deformation and the mechanical energy required for piezoelectric cells generate electricity. The energy generated by a piezoelectric single cell is relatively small, necessitating the use of multiple cells in a small contact area to increase the power generated by the system. The treatment of the signal generated by the cells is accomplished with piezoelectric rectification and filtering stages where the signal pulse generated is converted continuously being stored in capacitors. Ends up presenting a prototype mounted on a shoe to carry out tests and measurements of the system in order to ascertain the capacity to generate electricity from the piezoelectric effect, given that the energy generated by the system not currently used for any finally, thereby being wasted.
