Abstract
This thesis presents a power management system for a batteryless wireless sensor which was powered by a sediment microbial fuel cell (SMFC), a microbial fuel cell tester used to measure the performance of microbial fuel cells (MFCs) and a new ultra-low voltage charge pump (ULVCP) for ultra-low voltage (~300 mV) applications. Microbial fuel cells were used as the target energy source to demonstrate the operation of the power management system (PMS) under ultra-low voltage and low power conditions. In order to design power management systems for MFCs, a new device called the MFC Tester (MFCT) was developed to test the performance of MFCs. Depending on the MFC’s performance over time, the capacitor sizes can be optimized for maximum system efficiency. Lastly a new charge pump (ULVCP) was designed which can operate with an input voltage of 300 mV.
