Energy harvesting presents a promising transition from battery-powered IoT nodes to battery-less ones. This paper presents a hybrid light-RF energy harvesting system utilising a metasurface patch antenna capable of simultaneous light and RF energy harvesting without mutual performance degradation. The meta-surface design improves the bandwidth and mitigates the negative effect of the solar panel on the antenna performance, achieving RF transparency. Our design operates across the entire RFID band (0.865-0.928 GHz) with a peak gain of 7 dBi at 0.868 GHz, harvesting 176 µW of light power at 155 lx and 20 µW of RF power over the air at 0.85 GHz, offering a sustainable pathway towards battery-less IoT nodes.engProceedings paper10.1109/wptce62521.2025.11062193WOS:001545112700085
