Journal ArticleDOI
Toward energy harvesting using active materials and conversion improvement by nonlinear processing
TL;DR: This technique, called synchronized switch harvesting (SSH), is derived from the synchronized switch damping (SSD), which is a nonlinear technique previously developed to address the problem of vibration damping on mechanical structures, results in a significant increase of the electromechanical conversion capability of piezoelectric materials.
Journal ArticleDOI
A comparison between several vibration-powered piezoelectric generators for standalone systems
TL;DR: In this article, a comparison between four vibration-powered generators designed to power standalone transducers is presented, based on a particular processing of the voltage delivered by the piezoelectric material, which enhances the electromechanical conversion.
Journal ArticleDOI
Piezoelectric Energy Harvesting Device Optimization by Synchronous Electric Charge Extraction
TL;DR: In this article, a nonlinear approach to optimize the power flow of vibration-based piezoelectric energy-harvesting devices is presented, which maximizes the mechanical to electrical energy conversion.
Journal ArticleDOI
Buck-Boost Converter for Sensorless Power Optimization of Piezoelectric Energy Harvester
TL;DR: In this paper, the authors presented a comprehensive model for miniature vibration-powered piezoelectric generators and analyzed modes of operation and control of a buck-boost converter for the purpose of tracking the generators optimal working points.
Journal ArticleDOI
Pyroelectric energy conversion: Optimization principles
TL;DR: Practical implementation key points of pyroelectric energy harvesting are presented showing that the different thermodynamic cycles are feasible and potentially effective, even compared to thermoelectric devices.
