There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract: Energy harvesting has been applied widely to resolve power distribution challenges in standalone devices. However, prior techniques for continuous, high-power systems often result in excess overhead for low-power counterparts that have become increasingly important contributors to Internet of Everything (IoE) edge devices. This thesis investigates the development of energy harvesting and delivery systems for low-power low-duty-cycle devices. We begin by designing a power management scheme for on-demand power delivery to reduce battery power. After identifying critical challenges for low-power energy harvesting. We further propose a robust self-powered energy harvesting and delivery system (EHDS) design as a solution to achieve energy autonomy in standalone systems. The design demonstrates a complete ecosystem for low-overhead discrete conduction mode (DCM) harvesting while reducing harvesting window confinement and overall implementation footprint. Finally, a low-power authentication IC is demonstrated and projected designs for self-powered System-on-Chips (SoCs) are presented.
