The realization of futuristic functional and smart textiles hinges on converging advanced fabrication methodologies with textile engineering. Additive manufacturing techniques, including direct ink writing and screen printing, enable precise deposition of conductive, piezoelectric, and thermochromic inks onto woven substrates, facilitating low-cost, scalable production of flexible sensors and displays. Fiber-based approaches—such as multimaterial thermal drawing, coaxial electrospinning, and dip-coating—allow seamless integration of electrodes, micro-batteries, and optical fibers directly into yarns without compromising breathability or mechanical flexibility. Traditional textile processing routes, including weaving, knitting, and embroidery, further offer structural anchorage for functional elements, enabling distributed sensing networks across large fabric areas. Key emerging applications encompass continuous physiological monitoring (heart rate, temperature, sweat analysis), energy harvesting from body motion and solar irradiation, adaptive thermoregulation via phase-change materials or Joule-heating elements, and bidirectional human-machine communication through fabric-embedded antennas. Despite significant progress, critical challenges persist. Washability remains a primary concern, as repeated laundering degrades printed electrodes and compromises fiber interfaces. Power autonomy requires seamless integration of flexible energy storage or harvesting without weight or rigidity penalties. Scalable manufacturing, transitioning from laboratory demonstrations to roll-to-roll production, demands robust quality control and standardized testing protocols. Addressing these barriers through materials innovation, encapsulation strategies, and hybrid fabrication workflows will determine the trajectory toward truly autonomous, responsive garments—where sensing, computation, and actuation become inherent fabric properties rather than external attachments.
