Abstract The rapid expansion of Internet of Things (IoT) applications, wireless sensor networks, and intelligent monitoring systems has increased the demand for sustainable and autonomous power solutions. Conventional sensor systems generally depend on batteries, which create limitations related to maintenance requirements, replacement costs, limited lifespan, and environmental concerns. Energy harvesting technologies have emerged as an innovative approach for developing self-powered sensor systems by converting available environmental energy sources into usable electrical power.
This study examines the role of energy harvesting technologies in enabling sustainable and autonomous sensor systems. The research explores various micro-energy sources, including solar energy harvesting, piezoelectric conversion, thermoelectric generation, electromagnetic energy harvesting, and hybrid energy systems. A conceptual analytical framework supported by simulated observations is developed to evaluate the influence of energy harvesting capabilities on self-powered sensor performance.
The findings indicate that energy conversion efficiency, power generation stability, environmental adaptability, energy storage integration, and system reliability significantly contribute to the effectiveness of self-powered sensor networks. However, challenges including low energy density, environmental dependency, material limitations, integration complexity, and manufacturing costs continue to influence widespread implementation.
The study contributes to sustainable electronics and smart sensing research by highlighting the importance of energy harvesting technologies for developing maintenance-free and environmentally responsible sensor systems. The findings provide practical implications for researchers, engineers, IoT developers, and industries seeking advanced solutions for autonomous monitoring applications.
