The integration of smart sensing materials into textile products presents transformative opportunities in healthcare, sports, robotics, and human–computer interaction. Although textile-based smart wearables offer inherent advantages such as comfort, flexibility, and seamless integration into everyday life, making them ideal for continuous monitoring, their development is often limited by the complexity of current manufacturing methods and the intricate interplay between functional materials and the anisotropic, hierarchical structures of textile substrates. Existing fabrication approaches primarily rely on weaving conductive fibers into fabrics or attaching rigid sensors onto their surfaces. These methods pose significant challenges in achieving a balance between comfort, durability, and high sensitivity. Moreover, they often overlook the influence of textile substrates and fail to fully utilize the structural properties of textiles to enhance sensor performance. Therefore, there is a critical need for advanced fabrication strategies and a comprehensive understanding of fabric–material interactions to enable the direct integration of functional materials into textile structures while maintaining the essential performance characteristics required for ideal wearable devices. This dissertation proposes a Direct Ink Writing (DIW) 3D printing approach for fabricating high-performance textile-based sensors by understanding the interrelationship among conductive ink formulations, pr...
