Power management is a critical component for efficient energy harvesting from ubiquitous vibrations existing in our environment. Conventional power management circuits were designed based on a simple vibration source input with a single frequency. However, the practical scenarios are that the majority of the vibration sources, such as, the vibrations of a window near a busy street or the vibrations of a bridge induced by passing vehicles, are not tonal. They are time-varying or stochastic, which means the conventional power management circuits are not adapted to many practical applications. This project aims to design a more efficient power management circuit that can be adapted to more practical vibration circumstances.
