Piezoelectric Energy Harvesting Interface Circuits based on The Synchronized Switch Harvesting on Inductor Technique

Harvesting energy from environmental vibration sources constitutes a promising solution to enable the development of self-powered medical implants such as pacemakers. The objective of this thesis is to investigate highly efficient implementations of piezoelectric energy harvesting interface circuits based on the Parallel Synchronized Switching Harvesting on Inductor (P-SSHI)technique. Four highly efficient piezoelectric energy harvesting interface circuits based on P-SSHI technique were developed in this thesis. All of them can achieve at least 3 times improvements in terms of the harvested energy compared to full wave bridge rectifier under the same testing condition.
