Vibration-based energy harvesting using cantilevered piezoelectric beam has been extensively studied over the last decade. In this study, as an alternative to resonant piezoelectric cantilevers, we studied multiple patch-based piezoelectric energy harvesting from multiple vibration modes of thin plates. Analytical electroelastic model of the multiple patch-based piezoelectric harvesters attached on a thin plate is provided based on distributed-parameter modeling approach for series and parallel configurations of the patches. An experimental setup is built with series-configuration of double patch-based harvesters attached on the surfaces of all-four-edges clamped (CCCC) rectangular aluminum plate. Analytical simulations and experimental validations of power generation of the harvesters are performed in a case study. The experimental and analytical frequency response functions (FRF) relating voltage output and vibration response to force input are obtained. The analytical model is validated by comparing analytical and experimental FRFs for a wide range of resistive electrical boundary conditions. The harvested power output across the various resistive loads is explored with a focus on the first four modes of the aluminum plate. Experimental and analytical results are shown to be in agreement for multiple patch-based piezoelectric energy harvesting from multiple vibration modes of thin plates.

Review Current

The goal of this paper is to review current methods of energy harvesting, while focusing on piezoelectric energy harvesting. The piezoelectric energy harvesting technique is based on the materials’ property of generating an electric field when a mechanical force is applied. This phenomenon is known as the direct piezoelectric effect. Piezoelectric transducers can be of different shapes and materials, making them suitable for a multitude of applications. To optimize the use of piezoelectric devices in applications, a model is needed to observe the behavior in the time and frequency domain. In addition to different aspects of piezoelectric modeling, this paper also presents several circuits used to maximize the energy harvested.
