Flexible wearable electronics have great potential in a variety of applications from daily infotainment and personalized healthcare to military security. Here we report a new multifunctional e-textile fabricated via screen printing of new water-based conductive inks based on silver fractal dendrites. After spraying coating an invisible waterproofing agent, the as-fabricated multifunctional e-textiles exhibit excellent stretchability, electromechanical performance, waterproofness, air permeability, and wear resistance. The conductivity of the e-textiles can be as low as 88.1 mΩ/sq and the strain sensing range can be up to 150% with a maximum gauge factor of 119.4. We finally demonstrate that the new multifunctional e-textiles can be used to detect human motions and serve as an effective wearable thermal management unit. This printed e-textiles may bring new opportunities for wearable electronics and promoting their large-scale applications in many other fields.
