X-ray diffraction analysis confirmed the predominantly amorphous nature of the PT matrix along with the crystalline CuSnO<sub>2</sub> phase, while the observed variation in crystallite size indicates composition-dependent microstructural modification.

This review presents a quantitative analysis of recent developments in PEH covering materials and structural configurations as well as performance enhancement strategies and optimization approaches. This paper presents a comparative framework that links material properties, structural design, and system performance metrics such as power density, bandwidth, and efficiency into a unified framework. Electromechanical coupling and scalability of advanced piezoelectric materials, specifically lead-free ceramics, polymer composites and nanostructured systems are reviewed. Broadband energy harvesting is evaluated for structural innovations including non-linear bistable systems, multi-modal configurations, and frequency up-conversion mechanisms. The convergence and applications of optimization methods that are metaheuristic and recent intelligent approaches are also examined. By analyzing each harvesting technique there are some trade-offs that can be made when choosing to implement one over another such as harvested power, frequency range and system complexity. Finally, this paper highlights current research gaps and future work areas, focusing on self-powered multimodal sensors, piezo-pyroelectric hybrid energy harvesting systems, AI-based adaptive tuning, and large-scale deployment practices.
