For centuries, engineers and scientists have sought to develop materials that are stronger, more durable, and more resilient to environmental stress. Yet, no matter how advanced a material may be, it inevitably suffers from wear and tear. Bridges develop cracks, aircraft components degrade under extreme conditions, and electronic devices break down over time. Traditionally, such damage requires human intervention—maintenance, repair, or replacement. But what if materials could repair themselves, just as human skin heals after an injury? This question has driven the emerging field of self-healing materials , a groundbreaking area of research that promises to transform multiple industries by making materials more sustainable, cost-effective, and resilient. Inspired by nature, these materials have the ability to autonomously detect and repair damage , enhancing the lifespan and reliability of infrastructure, vehicles, electronics, and even biomedical devices. However, while the technol...
