This chapter presents the analysis and designs of efficient energy harvesting circuits interfacing two example energy generators: thermoelectric generator and piezoelectric generator. For both examples, it is important to understand their key characteristics in order to design circuits that can collect the maximum energy. For instance, a Energy harvesting devices such as piezoelectric elements and antennas capture ambient energy, but this energy has to be converted to DC for load and energy storage devices. For this high-efficiency power harvesting circuits are required. This article discusses important design aspects of energy harvesting circuits and their implementation. Harvesting Circuit. Energy management system components should have: High energy efficiency in capturing, accumulating, and storing small energy packets. Efficiency must be high enough to ensure that the energy consumed by the energy harvesting circuit is much smaller than the energy captured from the source.
