In a breakthrough that could reshape the future of functional apparel, researchers at National Yang Ming Chiao Tung University in Taiwan have developed self-healing fabrics designed to extend garment life and cut textile waste. Led by Professor Jiun-Tai Chen, the Optoelectronic Polymer Research Group has engineered polymer-based fibres and coatings that can recover from damage when exposed to controlled heat, pressure or light. After healing, the material can regain nearly 70 percent of its original strength, offering a practical answer to the throwaway culture associated with fast fashion.

Science Behind the Healing

The innovation rests on ionic gels formed by combining polymers of different crystallinity with ionic liquids. When fibres are damaged, molecular forces such as hydrogen bonding, electrostatic attraction and dipole interactions help the material reconnect and restore structure. These properties make the fabric especially suitable for demanding environments where durability matters most. Key application areas include:

• Ski jackets and mountaineering apparel

• Wetsuits and outdoor performance gear

• Camping tents and protective equipment

Beyond repairability, the fabrics can also deliver added value through conductivity, antimicrobial behaviour and sensing capability.

From Smart Apparel to Electronic Skin

Looking ahead, the research team is expanding the technology under a framework focused on synthesis, sustainability, smart design and application. Self-healing textiles could evolve into intelligent surfaces for smart wearables, medical textiles and even robotics. fabrics infused with sensing functions may act as electronic skin, able to detect pressure, temperature and touch. Such applications could transform areas ranging from infection-sensing medical gauze to robotic systems that interact more naturally with humans.

To bridge research and real-world use, the team is collaborating with national research institutes and industry partners, while exploring recycled material pathways and global academic partnerships. As self-healing textiles move closer to industrial adoption, the innovation signals a future where garments last longer, waste reduces and materials actively adapt to human needs.
