Electromechanical characterization of a bimorph piezo for Energy Harvesting applications in road infrastructures

Risultato della ricerca: Article

Abstract

Piezoelectric materials can be used as a means of transforming ambient vibrationsinto electrical energy that can be stored and used to power other devices. With the recentsurge of micro scale devices, piezoelectric power generation can provide a convenientalternative to traditional power sources used to operate certain types of sensors/actuators,telemetry, and MEMS devices. However, the energy produced by these materials is, inmany cases, far too small to directly power an electrical device. In the present study,piezoelectric devices will be investigated and experimentally tested to determine each oftheir abilities to transform ambient vibration into electrical energy. Tested piezoelectricdevices are the well-known bimorph piezoceramic material lead-zirconate-titanate (PZT-5A). The numerical results estimate the efficiency of this device tested and identify thefeasibility of their use in real world applications. The results presented in this paper showthe potential of piezoelectric materials for use in power harvesting applications. Thesimulation is carried by coupling the FEA commercial code COMSOL Multyphysics© andQUCS©, an open-source integrated circuit simulator able to setup a circuit and simulatelarge-signal, small-signal and noise behaviour of the circuit coupled with the FEM model.
