“…The physics and their coupling with boundary conditions will be addressed, followed by coupling with multiphysics based on the pre‐selected physics conditions. The process can be divided into three sections namely pre‐processing, solver, and post‐processing as depicted in Figure 1 64,65 Pre‐processing: contains the contribution of development issues by identifying the physical problems and considering the space dimension; Solver: governing equations solve on the geometry, mesh, materials properties, geometry and materials properties, boundary conditions, meshing and so forth; Post processing: reveals the aftereffects of solver by graphs plots, contour plots, velocity vectors and so forth. …”

Poly(vinylidene fluoride) (PVDF) is a promising piezoelectric and pyroelectric material for energy harvesting applications. This paper investigates the electrical outputs of PVDF microarrays using both simulation studies and theoretical calculations. The finite element method in COMSOL Multiphysics® is utilized to model PVDF microarrays and simulate their responses under mechanical loading and temperature changes. Theoretical calculations are also performed to estimate the piezoelectric and pyroelectric voltage outputs using established mathematical formulas. A series of PVDF microarrays are modeled in two dimensions with defined geometry, materials, boundary conditions, and parametric sweeps of wind speed and temperature. The simulation results for electrical outputs show good agreement with the theoretical calculations, demonstrating the validity of both approaches. The maximum voltage outputs are on the order of 10−3 V for the range of wind speeds from 6.5 to 11 m/s and temperatures from 319.3 to 336.3 K. In addition, the mechanical and thermal sensitivities are quantified. This work provides a framework for design and optimization of PVDF‐based energy harvesters. The combined methodology enables characterization of the relationships between operational conditions, PVDF microarray properties, and electrical outputs.

“…In Block-4 the optimal energy is stored into temporary storage device for charging process and automatic supply to the load. The storage device can be capacitor or super-capacitor which are the primary types of storage component (Naim Uddin et al, 2016;Musa et al, 2016). To overcome the power losses, a low leakage super capacitor is applied.…”

The paper deals with the growing interest of energy harvesting systems due to great development in many new emerging technologies in electronics and telecommunication. The research focuses particularly about rectenna element comprises of antenna, impedance matching and rectifier. The rectenna is applied under Micro-Electromechanical-System (MEMS) technology design use in Radio Frequency (RF) energy harvester. MEMS is a technology of miniaturization that has been mostly adopted from integrated circuit industry together on a chip that are made using micro fabrication technique and applied for not only electrical systems. RF ambient source is considered over other ambient sources because RF can be broadcasted by various wireless systems in unlicensed frequency bands. However, the amount of energy captured from the ambient RF is extremely low which need improvements and more Direct Current (DC) voltage generated from RF energy harvester. For this motivation, a dual band MEMS rectenna is proposed for maximizing the efficiency. Power Management Unit (PMU) is interposed between MEMS rectenna and a load. The system is equipped with temporary energy storage and voltage regulator to produce optimum output voltage. The paper proposes a system that is designed and simulated using PSpice software and modeled in Mentor Graphic. The stated result from RF MEMS energy harvester is to provide functional conversion efficiency and reliable energy harvesting system to reach 1.5-3.0 V output voltage for operating frequency at 1.9 and 2.45 GHz from RF input power at -20 dBm with reveal approximately 100% improvement over other existing designs. The conceptual design can be the platform for innovative developments in recent technologies to achieve wireless transmission powered only by RF MEMS energy harvester.

In this paper, the design of a micro-cantilever based solar energy harvester is proposed. Solar energy is converted to electrical voltage using a MEMS solar cell that uses the principle of coefficient of thermal expansion and piezoelectric effect. Initially, the bilayer cantilever made of two different materials (Al and SiO2) is displaced at the free end by absorbing the solar radiation that develops the stress at the fixed end and thus the solar radiation is converted to mechanical energy. Also, the developed mechanical energy (stress) is converted to electric potential by using the piezoelectric material that is positioned at the fixed end of the cantilever. Different shapes of bilayer cantilevers are designed and analyzed for maximum stress distribution. Experimental study on different shapes is also carried out in an INSTRON 8800 compression testing machine with the prototype made of aluminium. The results obtained prove that the triangular beam shows larger displacement and stress when compared with other shapes. Then the optimized structure with maximum stress is evaluated computationally for maximum voltage generation by placing different piezoelectric materials at the fixed end. The size of the designed solar cell is very small (4000 μm2) when compared to the conventional photovoltaic cell which ultimately reduces the cost by the batch fabrication process.
