Abstract

With the rapid development of the Internet of Things and intelligent structures, integrated piezoelectric energy harvesting and vibration reduction technologies aimed at self-powered monitoring and vibration suppression have become a research hotspot. Owing to mature structural mechanics, relatively low manufacturing cost and the ease of integrating piezoelectric elements, beam components have become the core load-bearing elements in piezoelectric energy harvesting and vibration control systems. Against this background, the fundamental theory of piezoelectric energy harvesting and beam-based vibration reduction is reviewed for typical prismatic and non-prismatic beam structures, including cantilever beams, L-shaped beams, U-shaped beams, and trapezoidal and tapered beams. The research progress regarding bandwidth extension, enhancement of energy conversion efficiency and improvement of vibration attenuation performance for these beam configurations is systematically summarized. Through a comparative analysis of the mechanisms and performance of different beam types, the key challenges faced by current beam-type piezoelectric energy harvesting–vibration reduction systems are identified, including nonlinear electromechanical coupling modelling, adaptability to broadband and multi-directional vibration environments, structural reliability and practical engineering application. On this basis, future development directions involving multi-field coupling, integrated co-design, introduction of smart materials and topological optimization are discussed. The review is intended to provide useful reference for structural design and engineering application of beam-type integrated piezoelectric energy harvesting and vibration reduction systems.
