**3. Conductive self-healing ECs for flexible applications**

Long-term operation of flexible electronic devices can lead to fatigue, corrosion, and damage, which ultimately culminate in significant device failure. To tackle this issue, researchers are actively investigating the potential of self-healing electronic devices. These devices possess the remarkable ability to automatically restore their electrical and mechanical performance in the face of mechanical damage, whether with or without external assistance. Integrating conductivity and self-healing functionality in flexible electronic devices is predicted to significantly enhance both their durability and performance. In this section, we emphasize the deployment of epoxybased self-healing polymer composites in various components and devices of flexible electronics, encompassing adhesives, coatings, sensors, electromagnetic interference (EMI) shielding, soft actuators, and energy devices.
