High-resolution liquid metal-based stretchable electronics enabled by colloidal self-assembly and microtransfer printing.

ABSTRACT: Liquid metal-based stretchable electronics offer high electrical performance and seamless integration with deformable systems but face challenges in achieving scalable, high-resolution patterning. In this work, we present a method for micropatterning liquid metal particle (LMP) films with feature sizes as small as 5 micrometers by integrating electrostatically enabled colloidal self-assembly and microtransfer printing. The resulting cold-welded LMP micropatterns exhibit exceptional electromechanical properties, high conductivity (2.4 × 10⁶ siemens per meter), stretchability (more than 1200%), and strain- and pressure-insensitive resistance, owing to their multiscale and dynamic morphologies.
