Abstract:
Lead-based piezoelectric materials like PZT pose environmental and health hazards, driving the need for lead-free alternatives in energy harvesting. This study focuses on the design and development of lead-free piezoelectric energy harvesting systems using materials such as potassium sodium niobate (KNN), bismuth sodium titanate (BNT), and barium titanate (BT).Advanced synthesis techniques enhance piezoelectric properties, while optimized device structures maximize energy conversion from mechanical vibrations. Experimental analysis and simulations confirm that lead-free materials achieve competitive performance compared to PZT. Applications in self-powered sensors, biomedical devices, and wireless electronics highlight their practical potential. This research advances eco-friendly energy solutions, promoting sustainable and efficient energy harvesting.
