Ionic Conductive Textiles for Wearable Technology

Abstract

Abstract Soft ionic conductors, characterized by their inherent flexibility and tissue‐like ion dynamics, are ideal for intimate applications such as wearable electronics for sensing, energy harvesting, signal transmission, and bioelectronics applications. Shaping ionic conductors into fiber and textile formats (i.e., ionic conductive textiles) to replace the focus on rigid electron‐based conductors heralds a transformative technology in wearable electronics and smart textiles, offering advantages that align with human‐device compatibility, wearability, and sustainability demands. In this review, the category of ionic conductors, the essential characteristics of ionic conductors, the methodologies for the fabrication and integration of ionic conductive textiles, and the diverse applications of these textile‐based soft ionic conductors are summarized. By providing perspectives and raising potential challenges on the future design and development of ionic conductive textiles in terms of sustainability, wearability, fabrication strategies, and integration with electrical systems, this review aims to highlight the potential of ionic conductors as key components for the next generation of wearable technologies and electronic textiles.
