The piezoelectric electromechanical parameters determine the maximum electrical power which is able to be transferred to an electric load. In this research work, an exhaustive study of the electromechanical parameters related to the piezoelectric material is carried out, modeling them as components of an electrical circuit, in order to analyze their influence on the transmitted power. On the other hand, some electrical loads are simulated to determine different matrix scenarios for a model developed by state-space equations in the Laplace transform domain. The results obtained have allowed to know how the piezoelectric material properties and mechanical characteristics influence the electrical power output of the energy harvester generator and the energy transmission behavior for different electric loads. The conclusions show how the different electromechanical parameters are related to each other, and how their combination transforms the mechanical environmental energy into the required electrical energy. The novelty of this research is the presentation of a model capable of obtaining the optimized working point of the harvester, taking into account not only the electric loads and current demands but also the piezoelectric material parameters. info:eu-repo/grantAgreement/EC/H2020/869884/EU/RE-manufaCturing and Refurbishment LArge Industrial equipMent/RECLAIM This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 869884-RECLAIM info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.9 2022 ENGINEERING, ELECTRICAL & ELECTRONIC 131 / 274 = 0.478 2022 Q2 T2 PHYSICS, APPLIED 72 / 160 = 0.45 2022 Q2 T2 COMPUTER SCIENCE, INFORMATION SYSTEMS 99 / 158 = 0.627 2022 Q3 T2 0.628 2022 Computer Networks and Communications 2022 Q2 Control and Systems Engineering 2022 Q2 Signal Processing 2022 Q2 Hardware and Architecture 2022 Q2 Electrical and Electronic Engineering 2022 Q2 4.7 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Gil-Hernandez, Daniel Hernando, Eduardo Quero, Fernando Bernal, Carlos Universidad de Zaragoza (orcid)0000-0001-9334-4870 5008 785 Universidad de Zaragoza Dpto.
