Journal ArticleDOI
Improved Design and Analysis of Self-Powered Synchronized Switch Interface Circuit for Piezoelectric Energy Harvesting Systems
Junrui Liang,Wei-Hsin Liao +1 more
TL;DR: A modified circuit and an improved analysis for the self-powered SSHI (SP-SSHI) are proposed, with the modified circuit, direct peak detection and better isolation among different units within the circuit are achieved, both of which result in the further removal on the dissipative components.
Journal ArticleDOI
Impedance Modeling and Analysis for Piezoelectric Energy Harvesting Systems
Junrui Liang,Wei-Hsin Liao +1 more
TL;DR: In this paper, the authors provided the impedance modeling and analysis for the PEH systems with different interface circuits, including standard energy harvesting, parallel synchronized switch harvesting on inductor, and series synchronized switch harvests on inductors.
Journal ArticleDOI
Energy flow in piezoelectric energy harvesting systems
Junrui Liang,Wei-Hsin Liao +1 more
TL;DR: In this article, an energy flow chart is introduced to comprehensively illustrate the energy paths within the PEH system, and three experiments are carried out with an SSHI device to measure its performances on energy harvesting, energy dissipation, and structural damping.
Journal ArticleDOI
A string-suspended and driven rotor for efficient ultra-low frequency mechanical energy harvesting
TL;DR: In this article, a string-suspended and driven rotor was used for energy harvesting from ultra-low frequency vibrations and human body motions. But the performance of the proposed approach was limited by the fact that it required two strings to suspend and actuate a rotor.
Journal ArticleDOI
