The growing global demand for sustainable energy has inspired scientists to develop innovative technologies that can harvest energy from our surroundings. Among these breakthroughs, lead-free nanogenerators have emerged as a game-changing solution for clean and self-sufficient power generation. These devices convert mechanical energy—such as motion, vibration, or pressure—into electrical energy using piezoelectric and triboelectric principles . Traditional nanogenerators often relied on lead-based materials, raising serious environmental and health concerns. In contrast, lead-free nanogenerators use eco-friendly materials like barium titanate, zinc oxide, and potassium sodium niobate, making them safe, biodegradable, and highly efficient. These next-generation materials offer exceptional flexibility, durability, and energy conversion efficiency while aligning with the goals of green chemistry and sustainable technology . The applications of lead-free nanogenerators are vast and tra...
