Piezoelectric business optimization for use in energy systems harvesting

In this work, commercial piezoelectric materials are electromechanically characterized, in different configurations for potential use in harvesting devices of mechanical energy, in order to store and use in the feeding of low power electronic systems. Optimization models considering two different types of mechanical energy are proposed: one for capture energy from continuous vibration, even low intensity and other for capture energy from impacts. Different configurations are discussed, and the feasibility of the models presented is analyzed by frequency vibration systems controlled and a test simulation of passing vehicles, designed and patented by POEMMA R&D group. Everyday applications in which devices in the configurations described may be used are listed. (C) 2015 SECV. Published by Elsevier Espana, S.L.U.
