This video demonstrates the SUPERIOT dual-mode wireless node, integrating RF and light-based links for both communication and energy harvesting. The system combines SWIPT (Simultaneous Wireless Information and Power Transfer), SLIPT (Simultaneous Lightwave Information and Power Transfer) and RF backscattering to enable a fully battery-less IoT node.
In the demonstration, the base station operates at 0.88 GHz and 2.48 GHz while LED transmitters provide optical signals at different modulation frequencies. The mobile node harvests energy through a dual-band RF rectifier and a photovoltaic interface, stores it in a capacitor and performs low-power communication via backscatter and light/RF downlink reception. This showcases a practical architecture for energy-autonomous sensing, communication, and localisation in future sustainable IoT deployments
The image shows an overview of the proposed hybrid RF and light localisation system, integrating SWIPT, SLIPT and RF backscattering for energy harvesting, communication and localisation in battery-less IoT applications.
