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...

Wake-Up Alignment for Batteryless Sensors

Batteryless network nodes could enable unprecedented ubiquitous sensing applications, while gathering energy from the environment and hence removing maintenance costs for batteries. However, these devices inherently suffer frequent power failures and reboots, due to the volatility of the incoming energy, thus classical synchronous message...
