The two main components of a self-powering solution are energy harvesting and energy storage devices. Energy harvesters derive their energy from the ambient eg in the form of solar, wind, and kinetic energy. Energy storage devices store the energy derived from the energy harvester. Energy harvesters integrated with an energy storage system can potentially replace batteries, creating a self-sustaining IoT platform. Furthermore, if the manufacturing of such devices is compatible with electronics manufacturing processes, then we can significantly reduce the cost of manufacturing. In this thesis, we describe carbon-based electrochemical capacitors and silicon-based piezoelectric energy harvesters as components of such a self-powered sensor node intended for on-chip integration with microelectronics while envisioning a better and greener future.
