Abstract: ABSTRACT [0012] The present invention introduces a novel self-powered RF energy harvesting system tailored for sustainable IoT sensor networks deployed in remote areas. By capturing ambient RF signals from various sources such as cellular towers, broadcast stations, and Wi-Fi networks, the system converts these electromagnetic waves into usable electrical energy with enhanced efficiency. Key innovations include a multi-band fractal antenna combined with a dynamic impedance matching network and a hybrid storage unit comprising supercapacitors and micro-batteries, all managed by an intelligent microcontroller that optimizes energy allocation based on real-time environmental conditions. This approach ensures continuous operation of low-power IoT sensors for data collection on parameters like temperature, humidity, soil moisture, and air quality. Experimental results demonstrate significant improvements in power conversion efficiency and operational lifespan compared to conventional battery-dependent systems, promoting eco-friendly deployments with reduced maintenance needs. The system is particularly suited for harsh environments, offering robustness against weather variations and signal fluctuations while maintaining data transmission reliability over long distances.
