Through the development and evaluation of alternative tunable stiffness mechanisms, particularly focusing on a discrete-tunable mechanism with three levels of torsional springs, significant improvements in energy capture and construction simplicity have been achieved. By optimizing dynamic models and conducting thorough structural analyses, potential weaknesses in the design have been identified and addressed. The innovative tunable mechanism, currently undergoing patent review, represents a substantial advancement in the field of renewable energy technologies, offering a promising solution for urban energy harvesting applications. This research underscores the importance of continuous innovation and optimization in energy harvesting systems to meet the evolving demands for sustainable energy production.eninfo:eu-repo/semantics/closedAccessVortexHarvesterVibrationWindTunableConference Object10.1109/GPECOM61896.2024.105827392-s2.0-85199089803
