A newly discovered method of generating electricity from human motion could revolutionize wearable tech and medical devices. Researchers have developed a flexible, biodegradable material that converts mechanical energy—such as footsteps or hand movements—into usable power without relying on traditional batteries. Early tests suggest the material could be integrated into clothing or implants, offering a sustainable alternative for low-energy applications. The breakthrough raises questions about scalability and real-world efficiency as scientists explore its potential beyond laboratory settings.
