The study developed a water-based environmental conductive ink based on silver fractal dendrites for fabricating multifunctional e-textiles with high conductivity, excellent strain sensing, and outstanding joule heating performance. These e-textiles have been successfully used to monitor human joint motion.
Herein, a water-based environmental conductive ink based on silver fractal dendrites is formulated and screen-printed onto the fabrics to fabricate the multifunctional e-textiles. Multifunctional e-textiles exhibit high conductivity (0.12 ohm/sq), excellent strain sensing performance (workable strain range of 105% with a gauge factor of 906.45), and outstanding joule heating performance (heated to 89 square at 1 V). The developed multifunctional e-textiles have been successfully used to monitor the motion of human joint (elbows and knees).
