The progression of self-sustaining, energy-efficient, and cordless gadgets has ignited a profound curiosity in the realm of power harvesting and the creation of compact dynamos. These generators tap into environmental power sources using piezoelectric energy harvesting materials, a process demonstrated through a comprehensive parametric analysis of a dual-layered actuator bar featuring an end-loaded beam, as modeled in Ansys. When subjected to an external force, the beam undergoes deformation and polarization. To harness this energy for small electronic devices (SEDs), an electrical circuit is employed to obtain electrical potential, or it can be contained within the battery for subsequent utilization. Initially, an exploration of six different piezoelectric materials highlighted PZT-5A as exhibiting the highest output voltage. Subsequently, a focused investigation into PZT-5A delved into the impact of distance, width, depth of the PEH material, end weight, and the repetition of the stimulus force on the generated outcome electrical potential. The findings underscored that increased distance, breadth, stimulus frequency, magnitude, tip mass, and thinner piezoelectric materials contribute to enhanced output voltage generation. This research assumes particular significance in addressing the fundamental needs of the Internet of Things and 5G technologies, where energy harvesting plays a pivotal role in powering detectors, micro-electro-mechanical systems, and various other portable gadgets. The end masses, varying from 10 to 250 g, were examined and analyzed for their impact on power production. It was observed that the direct current electric potential rises with an increase in the end mass. Specifically, an end mass of 250 g is capable of generating 35.5 mV of direct current electric potential. As the demand for efficient, sustainable power sources intensifies, the insights gleaned from this investigation hold promise for advancing the capabilities and applications of self-powered electronics in diverse technological landscapes.
