Healing wounds is a slow process, and it can be hard to tell if a cut is getting better or worse. To solve this, scientists made a "smart bandage" called a-Heal. It has a tiny camera and AI that acts like a 24-hour doctor. It looks at the wound and automatically gives the right medicine or a tiny electric boost to help cells grow. This makes wounds heal 25% faster. The big benefit is that people can heal much more quickly at home without needing to visit the hospital as often.
