Stretchable, Washable,\nand Anti-Ultraviolet i‑Textile-Based\nWearable Device for Motion Monitoring

Abstract

Smart textiles with multifunction and highly stable performance\nare essential for their application in wearable electronics. Despite\nthe advancement of various smart textiles through the decoration of\nconductive materials on textile surfaces, improving their stability\nand functionality remains a challenging topic. In this study, we developed\nan ionic textile (i-textile) with air permeability, water resistance,\nUV resistance, and sensing capabilities through in situ photopolymerization\nof ionogel onto the textile surface. The i-textile presents air permeability\ncomparable to that of bare textile while possessing enhanced UV resistance.\nRemarkably, the i-textile maintains excellent electrical properties\nafter washing 20 times or being subjected to 300 stretching cycles\nat 30% tension. When applied to human joint motion detection, the\ni-textile-based sensors can effectively distinguish joint motion based\non their sensitivity and response speed. This research presents a\nnovel method for developing smart textiles that further advances wearable\nelectronics.
