Abstract-Intelligent systems like automatic highway traffic management, area surveillance, and geological activity monitoring require substantial data collection and processing in the field. Energy self-sustainability is a critical foundation for successful field systems that are away from the power grid infrastructure. Instead of the conventional battery-based energy storage, this paper argues that the super capacitor buffering of solar energy (SOLARCAP) has the advantages of precise energy lifetime awareness, low maintenance, and operational robustness. By designing and developing a prototype implementation of the circuitry required for management and harvesting of energy, we demonstrate a SOLARCAP system that ensures safe device operation within the permitted voltage range.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
