Inkjet printing is a scalable processing technique to fabricate smart textiles through deposition of electronic materials based on drop-on-demand (DOD) system. As a postprocessing method, inkjet printing is a cost-effective strategy to fabricate e-textiles with versatile patterns using automated systems. Inkjet printing is a widely accepted technique to fabricate high functionality electronic devices in flexible electronics whereas the application to textile platform is highly challenging. Congruous knowledge in rheology, characteristics of electronic materials, textile science, mechanism of electronic devices is required to achieve our goals in inkjet printing smart textiles. As the first study, a novel technique of inkjet printing e-textiles with particle free reactive silver inks on knit structures is developed. The inkjet printed e-textiles are highly conductive with sheet resistance of 0.09 {acute}{84}{OElig}/sq by means of controlling the number of print passes, annealing process and textile structures. It is notable that the inkjet process allows textiles to maintain inherent properties including stretchability, flexibility, breathability and fabric hand after printing process. This was achieved by formation of ultrathin silver layers surrounding individual fibers. In the second study, the compatibility of MOD silver inks and polymer dielectrics of UA and PVP/PMF is demonstrated by process optimization and followed characterization. Unique dual-layered polymer dielectrics' intra- and inter-layer chemical interaction was able to enforce adhesion with excellent separation interfaces of MOD silver inks which typically dissolve dielectric layers easily. This led to significant enhancement of metalpolymer interfaces. The surface microstructure of film and textiles were compared to fabricate capacitance. The reliable samples were further characterized with performance as capacitor and electromechanical response for the further capacitive sensing applications. The third study includes a work in a continuous and thorough investigation in inkjet printingMOD silver inks for high conductivity, accurate pattern resolution and cost-effective materials processing for multiplexed e-textile circuits was demonstrated. The ink characterization for suitability for inkjet processing and the textile microstructure-ink interface relationship significantly affected performance of e-textiles. The simultaneous O-PTIR/Raman spectroscopy is a non-contact and non-destructive chemical and microscopic method which has significant potential for understanding functionalities of the inkjet printed e-textiles. As print parameters centered in drop spacing and print passes affect the level of electrical conductivity, pattern resolution and the materials efficiency with consideration of large area patterning. The large area multiplexed circuits prepared with inkjet printing on textiles showed the great potential for the e-textile circuits performance in wearable electronics system development.
