Wearable technology for 2D MXene based supercapacitors

The growing demand for wearable electronics has intensified the need for lightweight, flexible, and high-performance energy storage systems. MXene-based supercapacitors have emerged as a promising solution due to their high electrical conductivity, large surface area, mechanical flexibility, and excellent electrochemical performance. These features enable rapid charge–discharge capability, long cycling stability, and seamless integration with flexible and stretchable substrates. This study reviews the application potential of MXene-based supercapacitors in wearable technologies such as health monitoring systems, fitness trackers, smart textiles, and AR/VR devices. In addition, key challenges, including large-scale production, oxidation stability, electrolyte compatibility, and mechanical durability, are discussed. Recent strategies to enhance material stability and device performance through surface modification and hybrid configurations are highlighted. MXene-based supercapacitors are expected to play a crucial role in the development of next-generation self-powered and smart wearable systems.
