Energy harvesting as an alternate power source in miniaturized implantable medical devices, especially cardiac and neural implants has been investigated. An electret-based angular electrostatic energy harvester has been proposed along with a power management control circuit to harvest maximum possible energy. The proposed harvester incorporates the properties of both area-overlap and gap closing topologies to achieve larger capacitance variation with respect to displacement as is observed in
