“…This optimization enhances the mechanical energy transferred to the electromagnetic device, thereby increasing the generated voltage [14,31,77]. The voltage output generated by the electromagnetic device attached to the variable-length pendulum depends on factors such as the strength of the magnetic field, the number of wire turns in the coil, the velocity of the pendulum, and the efficiency of the energy conversion process [78][79][80][81]. Electromagnetic devices attached to variable-length pendulums have applications in energy harvesting from various sources of mechanical motion, including vibrations, oscillations, or even human movement, thus yielding a sustainable and even renewable power source for low-power electronics, networks of sensors, or remote monitoring systems.…”

“…Musharraf et al explored an interesting concept involving a wing-oscillating coil rod pendulum that is designed to generate a low current and voltage [79]. Central to this system lies a copper coil pendulum, which interacts with a flapping wing that is attached to it, oscillating at a low frequency upon wind impact.…”

“…To overcome the constraints of a simple pendulum confined to a plane and its restricted degree of excitation, as shown in Musharraf et al [79], the dynamics of a spherical pendulum experiencing translational support excitation in three directions under generic forcing conditions were explored in the study by Sommermann et al [97]. The system is represented using two generalized coordinates to enhance pre-prototypes and to explore the impact of the power take-off on pendulum dynamics.…”

The ability to power low-power devices and sensors has drawn a great deal of interest to energy harvesting from ambient vibrations. The application of variable-length pendulum systems in conjunction with piezoelectric or electromagnetic energy-harvesting devices is examined in this thorough analysis. Because of their changeable length, such pendulums may effectively convert mechanical vibrations into electrical energy. This study covers these energy-harvesting systems’ basic theories, design concerns, modeling methods, and performance optimization strategies. This article reviews several studies that look at dynamic models, the effects of damping coefficients, device designs, and excitation parameters on energy output. The advantages and disadvantages of piezoelectric and electromagnetic coupling techniques are demonstrated by comparative research. This review also looks at technical advances and future research prospects in variable-length, pendulum-based energy harvesting. An expanded model for an energy harvester based on a variable-length pendulum derived from the modified, swinging Atwood machine is more specifically presented. This model’s numerical simulations, estimated current and voltage outputs, and produced power from the electromagnetic and piezoelectric devices integrated at various points in a 4-DOF variable-length pendulum model all indicate encouraging results. This necessitates extra study, changes, and optimizations to improve the usefulness of the proposed model. Finally, important dynamic models on developing variable-length, pendulum-based energy harvesters for usage in a range of applications to create sustainable energy are summarized.

“…There are many techniques to implement this conversion such as piezoelectric, electrostatic, and electromagnetic. The most popular method is the electromagnetic approach used in this study, as illustrated in [20]. A finite element model for the cantilever employs the Euler-Bernoulli beam theory to investigate the bladeless wind turbine dynamic behaviour.…”

Green energy applications have been a promising research area last two decades. One of these applications is using the power of wind for electrical power generation; wind turbines with different designs have great importance in this field. However, capturing energy from wind by using traditional wind farms has several limitations such as large installation space, specified airflow conditions, shading effect, noise, and design and maintenance complexity. Bladeless wind turbines have been used to convert wind energy into useful kinetic energy to overcome these obstacles. This paper introduces numerical and experimental investigations of a bladeless wind turbine for harvesting energy from wind. The proposed design has a cylindrical structure to resonate at a wide range of wind speeds and directions, which can maximize the harvested energy. Eigenfrequency simulation modules were developed to determine the structure's natural frequencies and mode shapes which aimed for continuous tunning with the generated vortex shed frequency. Furthermore, the numerical investigations extended to simulate the fluid-structure interaction (FSI) analysis to accurately define the dynamic response of the bladeless wind turbine under different air-flow conditions. The resulting kinetic energy is delivered to an alternator to convert it into electrical power.
