Abstract

Abstract

With the increasingly prominent challenges of energy shortages and environmental issues, the development of clean and renewable energy has become a global consensus. Owing to their abundant reserves and renewable nature, wind and water energy are regarded as promising sources for energy harvesting. Mechano-electric coupling mechanisms determine the output power and bandwidth adaptability of energy harvesters and therefore provide an important approach to improving energy harvesting efficiency. This review summarizes recent advances in the application of mechano-electric coupling effects to wind and water energy harvesting, with particular emphasis on energy capture mechanisms based on dynamic instabilities, theoretical modeling methods, and performance enhancement strategies. For wind energy harvesting, typical flow-induced vibration phenomena, including vortex-induced vibration, flutter, and galloping, are discussed with a focus on their nonlinear dynamic response characteristics. Recent progress in broadening the effective operating bandwidth and improving electromechanical conversion efficiency through structural configuration optimization, the introduction of nonlinear mechanisms, and multi-degree-of-freedom coupling designs is also reviewed. For water energy harvesting, linear resonance responses and nonlinear frequency-up-conversion techniques used in macroscopic wave energy harvesting are summarized in terms of their effectiveness in improving energy conversion efficiency, and the micro- and nanoscale mechanical characteristics involved in microscale liquid-water energy harvesting are discussed. Finally, future trends in mechanics-based design for energy harvesting technologies are outlined.
