Hybrid Energy Harvesting Techniques for Self-Powered Electronic Devices

Authors/Creators

Description

The increasing demand for sustainable and maintenance-free power sources for modern electronic systems has driven research into energy harvesting technologies for self-powered devices. This study investigates a hybrid energy harvesting system that integrates solar, piezoelectric, and thermoelectric energy sources to improve power reliability and efficiency. A mathematical modeling and simulation-based approach using Optisystem was employed to evaluate the performance of individual energy harvesting modules and their combined output under varying environmental conditions. The system incorporates power conditioning circuits, energy storage units, and power management strategies to ensure efficient energy conversion and utilization. Simulation results indicate that solar energy provides the highest contribution (12 W), while piezoelectric (6.084 W) and thermoelectric (2.304 W) modules offer significant complementary power. The hybrid system achieved a total output of 20.388 W, demonstrating enhanced energy availability and continuity compared to single-source systems. The findings highlight the suitability of hybrid energy harvesting systems for applications such as wireless sensor networks, wearable electronics, and remote monitoring systems, where continuous and reliable power is essential. Hybrid energy harvesting provides a robust and sustainable solution for next-generation self-powered electronic devices, although further improvements in system integration and cost optimization are required for large-scale deployment.
