| Abstract Scope |
Electronic device miniaturization has driven component study to the nanoscale, sparking interest in nontraditional packaging substrates for targeted device fabrication and design. The emerging field of ‘e-textiles’ examines the translation of traditional manufacturing strategies onto flexible textiles to establish functional garment devices. We investigated the modification of textiles with nanosolder-inks, establishing conductive communication channels and joining resistive sensing elements through non-destructive soldered interconnection. Low melting temperature tin/indium nanosolder particles were synthesized and formulated into conductive inks at various loadings. These nanoinks were applied to threads of differing fabric blends by dip-dry coating, alongside thermal/electrical processing to improve adhesion. Exposure to infrared heating enabled targeted nanosolder melting without harming the fiber structure. Following melting, threads modified by nanoinks with incorporated graphene oxide demonstrated sensing capability (e.g., temperature, humidity, liquid phase salinity, or chemical vapors). Generated signal was transmitted via thread-to-thread soldered joining, demonstrating robust, non-destructive interconnection within a conductive textile platform. |
