This paper "A 2-Mode Reconfigurable SSHI Rectifier with 3.2X Lower Cold-Start Requirement for Piezoelectric Energy Harvesting", by Xinling Yue and Sijun Du, proposes a 2-mode reconfigurable rectifier with low input open circuit (VOC) for piezoelectric energy harvesting. The rectifier works as a voltage multiplier in cold state, while switches to synchronous switch harvesting on inductor (SSHI) rectifier combined with a full bridge rectifier after the cold state ends, which lowers the requirement for the start-up voltage by 3.2X. This enables the energy harvester start harvesting energy at much lower excitation levels.
