Sistema de recolección de energía proveniente del ambiente utilizando un sensor piezoeléctrico

Abstract

Energy harvesting coming from the environment generally from unused sources is essential in a society with growing energy demand. In most cases, these sources have limited amounts of energy, which can be used in low-power devices and limited access areas. As a solution to this type of problem, technologies capable of taking advantage of this energy are developed, thanks to the creation of self-powered systems that also have a better impact on the environment. Entering in this technology two devices are postulated, the SPV1050 and the ADP5091, capable of storing, managing, and supplying the energy collected by specific transducers: photovoltaic cells and piezoelectric sensors. Simultaneously, the behavior of an acoustic energy harvester is analyzed. From its simulation in the Ansys CAE tool, solving the problem in a decoupled way, the modal response of a Helmholtz resonator with the hexagonal section is obtained. Likewise, the modal and voltage response of the series bimorph piezoelectric cantilever beam is achieved. The analysis carried out has the purpose of finding the behavior of the collection system for future implementation, making use of some of the proposed management systems.
