Abstract

Liquid metals are ideal materials for fabricating stretchable circuits in wearable devices, becoming printable metallic inks with high conductivity by blending with solid nanoparticles. However, challenges related to reliability arise, including variation of printing patterns, and electrical damage during repeated stretching. Here, we report a novel metallic ink containing biphasic alloys, obtained by annealing the liquid metal-based mixture. The solid-phasic alloy adheres to the surface of nanoparticles, creating an anchoring effect with liquid-phasic alloy to enhance the reliability of stretchable circuits based on this novel printable metallic ink.
