Programmable Microcontroller Based Power Management Module for Batteryless intermittent Computing Systems

The maturity of energy harvesting technologies and low-power microcontrollers creates the prospect of developing batteryless computing for wireless sensor networks and i.o.t applications. One of the challenges mitigating the sustainability of batteryless computing is the intermittence and regulation of harvested energy which hinders the prolonged execution of batteryless computing applications. This paper aims to propose a novel power management module by leveraging a programmable microcontroller using an open-source, energy-aware software framework to implement a low-cost power management module for batteryless intermittent computing solutions. The design and implementation consist of integrating DC to DC power regulating topology and the characteristics of a general purpose, ultra-low power mixed signal microcontroller to implement a power management module that regulates DC output voltage and offers many more functionalities for batteryless intermittent computing applications.
