However, these systems face significant challenges in energy management, which become even more complex when devices are required to collaborate with one another. In this demo, we showcase ScAlg, a decentralized algorithm that leverages wake-up receivers to scatter wake-up times within a fully connected network of batteryless devices. This approach improves operational continuity and reliability under strict energy constraints. Our hardware setup demonstrates how batteryless nodes utilize wakeup receivers to coordinate their wake-up schedules based on energy availability dynamically, enabling sustained operation and collision-free communication.enhttp://rightsstatements.org/vocab/InC/1.0/Technology::621: Applied Physics::621.3: Electrical Engineering, Electronic Engineering::621.38: Electronics, Communications EngineeringComputer Science, Information and General Works::004: Computer SciencesConference Paperhttps://doi.org/10.15480/882.1601110.22032/dbt.6711910.15480/882.16011Renner, Bernd-ChristianBernd-ChristianRennerConference Paper
