Energy harvesting from wind-induced flutter using piezoelectric Polyvinyledene Fluoride (PVDF) was investigated. Previous studies suggested that coupled bending-torsion mechanical vibrations were capable of producing about 30% more power output compared to a pure bending case. In this work, asymmetrical configurations, with amplification devices hinged to the PVDF, capable of bending-torsion vibrations were investigated for energy harvesting from fluid flow. Results indicated that asymmetrical configurations, when excited by fluid flow, were more prone to chaotic flapping and hence provided lower power output compared to a symmetrical harvester. Also, asymmetrical configurations were more prone to fatigue due to excessive non-linear strains. A detailed study of the power output, flutter behavior, piezoelectric operating modes and their limitations are provided in this work.

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.
