“…The work in this paper extends the results obtained in the context of damping or energy harvesting of vibrating plates in still fluid [33,42] to flow-induced instabilities and more than one piezoelectric patch. The present results allow to conclude that the optimal location for piezoelectric energy harvesting along the plate is on the downstream half, and in that regard are reminiscent of the conclusions of Ref.…”

International audienceFluttering piezoelectric plates may harvest energy from a fluid flow by converting the plate's mechanical deformation into electric energy in an output circuit. This work focuses on the influence of the arrangement of the piezoelectric electrodes along the plate's surface on the energy harvesting efficiency of the system, using a combination of experiments and numerical simulations. A weakly non-linear model of a plate in axial flow, equipped with a discrete number of piezoelectric patches is derived and confronted to experimental results. Numerical simulations are then used to optimize the position and dimensions of the piezoelectric electrodes. These optimal configurations can be understood physically in the limit of small and large electromechanical coupling

The amount of energy usage per person has shown to increase with every year. With increase in population and depletion of non-renewable sources of energy, there is a growing need for the development of energy harvesters using renewable sources of energy. This paper aims to set a base study to address the problem of lack of energy harvesters using a lesser known renewable source of energy-rain. This paper presents a theoretical rooftop model that has been subjected to a mix of wind-water fluid simulate conditions of a rainy weather and the test data were recorded. ANSYS analysis has been performed with the fluid velocity being set at 20 m/s, 30 m/s, 40 m/s and 50 m/s which strikes the roof of a building kept at 0°, 45° and 60°. The objectives of this paper is to determine the amount of voltage that can be generated from pressure developed by the fluid striking the model surface. The pressure values, obtained from ANSYS simulation, were then used to show that the method is viable to be applied on piezoelectric cells to generate electricity from rain and wind hence the study can be used to develop a sustainable model using rain as a renewable source of energy. Low level voltage can be generated from rain striking on piezoelectric material.

“…The energy output/input can be extremely sensitive to the length and location of the piezoelectric patches. Optimal placement of piezoelectric material for cantilever beams for power harvesting efficiency are considered in [15,16]. Controlling the shape of a laminated beam by an optimally placed piezo actuator for minimizing the maximum deflection is studied in [17][18][19].…”

The paper investigates how the energy input/output of a composite plate with piezoelectric patches, acting as a sensor, actuator, or energy harvester, can be regulated by changing the parameters of the piezoelectric patches, the external vibrating frequency and the boundary conditions imposed on the host platelayer. It is shown that for any size of the piezoelectric patches there is always one location where the energy input/output reaches a maximum, whether the process is very low frequency or higher frequency. Furthermore, for a dynamic vibrational loading the energy input/output is highly sensitive whether the operating frequency is below or above the system's resonance frequency. For the operating frequency close to but below the resonance frequency, the location for the maximum energy input/output is considerably different from the optimal location when the operating frequency is just above the systems resonance frequency. That is to say, a slight change in the operating frequency around the resonance frequency can make a considerable difference to the optimal locations for the piezoelectric patches for maximum energy input/output.
