Keeping Track of Time on Energy Harvesting Systems


Energy-harvesting devices have enabled Internet of Things applications that were impossible before. Power failures are the norm for these battery-less devices, imposing a challenge to maintain a continued notion of time on these energy restricted devices. To address this challenge we introduce a novel time measurement architecture for energy harvesting devices. Compared to existing solutions, our solution not only improves the start-up time but also reduces the required energy to measure a duration of time.
