Micro colheita de energia através de piso vibratório com sistema piezoelétrico

Abstract

Sustainability, over the years, has become a concept widely studied and applied, being linked to sustainable development, making its applicability possible only with an integrated view of the social, economic and environmental spheres. Following this assumption, the pavement emerges as a sustainable alternative for energy generation independent of climatic factors. The pavement is considered the meeting point for people and vehicles, and through it it is possible to obtain electrical energy through the transformation of the mechanical energy transmitted by vehicles or pedestrians, using piezoelectric devices. In this context, a small scale energy collector prototype was designed with LDT1-028K polymeric piezoelectric materials whose vibrations are generated by the flow of people on the structure called the vibrating floor. Three tests of different flows passing under the vibrating floor were simulated, simulation of slow walking steps called M1, simulation of intermediate walking steps called M2 and simulation of running steps called M3. The results obtained showed an increasing increase in the effective voltage output as the simulations varied from slow steps to running steps, respectively. A voltage of 0.967 V was obtained for the M1 simulation, 1.217 V for the M2 simulation and 1.788 V for the M3 simulation. Furthermore, it was observed that, despite surpassing some results found in the literature, future works use another piezoelectric model and different materials for the cantilever beam, so that the system can be activated, generating its optimal results.
