Abstract : Electrostatic vibrational energy harvester (e-VEH) appeals to the ever expanding applications of self powered sensors. The capacitive transduces and their conditioning circuits are extensively studied in literature, yet usually lacking a load interface that manages that energy extraction from the harvester and efficiency delivers it to a load. A load interface, as well as its controller, designed for Bennet's Doubler conditioning circuit is presented in this work. The energy extraction from the harvester is achieved through a multiple energy-shot transfer process to minimize the resistive energy loss. The load interface controller simulation shows a low power overhead of less than 100nW making it adequate for practical implementation.
