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.

Energy Harvesting System

Ambient energy harvesting using piezoelectric transducers is becoming popular to provide power for small microelectronics devices. The deflection of tires during rotation is an example of the source of energy for electric power generation. This generated power can be used to feed tire self-powering sensors for bicycles, cars, trucks, and airplanes. The aim of this study is to optimize the energy efficiency of a rainbow shape piezoelectric transducer mounted on the inner layer of a pneumatic tire for providing enough power for microelectronics devices required to monitor tires. For this aim a rainbow shape piezoelectric transducer is adjusted with the tire dimensions and excited based on the car speed and strain. The geometry and load resistance effects of the piezoelectric transducer is optimized using Multiphysics modeling and finite element analysis.

Energy harvesting is the technology to extract energy from environment with many surrounding sources of energy. From these sources it is used to extract less electrical power energy and boost up tiny electrical systems or amount of energy stored in a battery. Many methods in energy harvesting among one of the method for harvesting energy is piezoelectric transducers. Energy harvesting depends upon so many factors like conducting circuit, number of sensors, and coupling coefficient of piezoelectric sensors with electromechanical. For large scale applications, one of the best suited technique energy harvesting .

This article aims to provide a comparative study on the functions of piezoelectric energy harvesting, dissipation, and their effects on the structural damping of vibrating structures. Energy flow in piezoelectric devices is discussed. Detailed modeling of piezoelectric materials and devices are provided to serve as a common base for both analyses of energy harvesting and dissipation. Based on these foundations, two applications of standard energy harvesting (SEH) and resistive shunt damping (RSD) are investigated and compared. Furthermore, in the application of synchronized switch harvesting on inductor (SSHI), it is shown that the two functions of energy harvesting and dissipation are coexistent. Both of them bring out structural damping. Further analyses and optimization for the SSHI technique are performed.

Direct Piezoelectric Effect

Energy transduction between the mechanical and electric effects has been evaluated over the years. Energy harvesting based on the direct piezoelectric effect using the curvature structures is a new endeavor in engineering applications. This study focuses on energy harvesting from mechanical vibrations through a simply supported circular cylindrical shell laminated with segmented piezoelectric energy harvester patches. The voltages (or modal signals) induced by the modal strains of the piezoelectric patch due to the direct piezoelectric effect can be further converted to modal energies. Spatial distributions of the modal energies are evaluated and compared in three piezoelectric energy harvester patch sizes, and key design parameters. The objective of this study is to investigate the spatial distribution characteristic of the modal energy and evaluate the effects of energy harvester patch size and physical parameters on the generation of the modal energy. These data evaluated in this study can be used as guidelines to design the optimum piezoelectric energy harvester in practical engineering applications.

Harvesting Systems

One of the most important techniques for energy harvesting is the clean energy collection from the ambient vibration. Piezoelectric energy harvesting systems became a hot topic in the literature and attracted most researchers. The reason behind this attraction is that piezoelectric materials are a simple structure and provide a higher power density among other mechanisms (electromagnetic and electrostatic). The aim of this manuscript is to succinctly review and present the state of the art of different existing vibrational applications utilizing piezoelectric energy harvesting technique. Meanwhile, the main concentration is harvesting energy from a vehicle suspension system. There is a significant amount of dissipated energy from the suspension dampers that is worthy of being harvested. Different mathematical car models with their experimental setup are presented, discussed, and compared. The piezoelectric material can be mounted in different locations such as suspension springs, dampers, and tires. The technique of implementing the harvester and the amount of power harvested from each location are analyzed. The evaluation of the electrical harvesting circuits and different storage devices for the harvested power are also discussed. The paper will also shed light on the variety of potential applications of the harvested energy.
