**Abstract**

The rapid advancement in electronics, electric vehicles, and grid storage has created a growing need for cutting-edge electronic devices. Researchers are actively investigating innovative materials that can withstand mechanical stress, exhibit electrical conductivity, and self-repair to ensure top-tier performance in various scenarios. Traditional polymer materials, though versatile, often lack the necessary qualities to meet the rigorous demands of flexible electronic and energy applications. To address these limitations, a significant breakthrough has emerged with conductive self-healing epoxy composites. These composites incorporate conductive materials into the polymer matrix, providing them with electrical conductivity, making them ideal for use as active components in electronic systems. Moreover, the integration of self-healing mechanisms significantly enhances their durability, countering performance degradation from mechanical stress. This chapter explores the recent developments in electrically self-healing epoxy-based polymer composites, with a focus on intrinsic self-healing mechanisms, evaluation strategies, the design of the conductive network in these composites, and their diverse applications in electronic components. These applications encompass adhesives, anti-corrosion coatings, sensors, EMI shielding, soft actuators, and energy storage/harvesting devices such as supercapacitors, batteries, and nanogenerators. The chapter also addresses the challenges and prospects of advancing flexible devices, paving the way for more reliable and efficient electronic systems in the future.
