<p>Energy harvesting from vibrations present in nature and converting it into electrical energy allows for the recovery of wasted energies and their optimal use. The generated electrical energy can serve as a cost-effective, continuous, and clean source to power low-consumption devices such as sensors, actuators, controllers, and medical equipment. This paper features a rigid horizontal cylinder that exhibits only vertical motion and is constrained by four springs. When wind interacts with the cylinder, a vortex-induced force is exerted on it, causing vibrations perpendicular to the wind flow. Inside this cylinder, a magneto-piezo-elastic (MPE) energy harvesting system is installed, connected to the horizontal cylinder via a fixed beam. The horizontal movement of the cylinder induces forces at the end of the beam, resulting in vibrations of the MPE beam. The nonlinear vortex-induced force due to the wind interaction with the horizontal cylinder is calculated using the Van der Pol equation, and its effect on the system’s vibrations is investigated. Subsequently, electrical energy is harvested in the form of voltage using a piezoelectric element mounted on the beam. Here, the optimal wind speed and resistance are calculated to maximize the output electrical power. Eventually, the effects of various parameters on the output power are examined. This study presents a novel magneto-piezo-elastic energy harvesting system that simultaneously absorbs vibrations and generates electrical energy from vortex-induced vibrations (VIVs) around a rigid horizontal cylinder. Unlike previous works, the system integrates both vibration absorption and energy harvesting in a single device, utilizing the combined effects of magnetic forces and piezoelectric elements. The optimal design parameters for maximizing the energy output are also identified, contributing to the development of efficient, sustainable energy harvesting systems.</p>
