Introduction to Vibration-Based Piezoelectric Energy Harvesting I. C. Lien1 Y. C. Shu2 1 2 (National Taiwan University) 130 SSHI (Synchronized Switch Harvesting in Inductor) SSHI This document provides an introduction to vibration-based piezoelectric energy harvesting. It summa- rizes the recent research activities of the authors in this field. The contents are divided into three parts: the design of piezoelectric power structures, energy-storage circuits and harvesting electronic interfaces. The electrical behavior of an energy harvesting system is able to be predicted based on the proposed analysis; moreover, some opportunities for new devices and improvements in existing ones are also indicated here. /Key Words (Electrical Damping) (Energy Harvesting) (Piezoelectric Materials) SSHI (Synchronized Switch Harvesting on Inductor) (Vibration-based Piezoelectric Energy Harvesting) Industrial Materials Magazine
