Bor-Shiun Lee,Shun-Chiu Lin,Wen-Jong Wu,Xuan-Yu Wang,Pei-Zen Chang,Chih-Kung Lee,Chih-Kung Lee +6 more
TL;DR: In this article, the authors presented the development of two piezoelectric MEMS generators, {3-1} mode and {3 -3} mode, which have the ability to scavenge mechanical energy of ambient vibrations and transform it into useful electrical power.
Journal ArticleDOI
Revisit of series-SSHI with comparisons to other interfacing circuits in piezoelectric energy harvesting
TL;DR: In this paper, an improved analysis accounting for the effect of frequency deviation from resonance on the electrical response of an SSHI system has been proposed to investigate the electrical behavior of a series-SSHI system.
Proceedings ArticleDOI
Tunable resonant frequency power harvesting devices
TL;DR: In this article, a tunable resonant frequency power harvesting device in cantilever beam form which will shift its resonant frequencies to match that of the external vibrations was developed and verified.
Journal ArticleDOI
Modeling and experimental verification of synchronized discharging techniques for boosting power harvesting from piezoelectric transducers
TL;DR: In this article, the authors present analytical models for studying the transient behavior of several power harvesting circuit topologies for use with piezoelectric bending transducers, and they compared to a matched resistive load case.
