Abstract: A method for forming conductive and stretchable traces on a substrate is disclosed. A photocurable ink is prepared by dispersing surface-modified liquid-metal particles in a solvent together with monomers, crosslinkers, dispersant, and photoinitiator. The ink is deposited onto a substrate and selectively exposed to patterned light to initiate photopolymerization and crosslinking of the functionalized particle surfaces, forming a patterned liquid-metal-polymer composite anchored to the substrate. Subsequent mechanical activation ruptures oxide shells surrounding the particles and allows the liquid-metal cores to merge into a continuous conductive layer that conforms to the projected pattern. The process operates under ambient conditions with low energy input and short exposure time, providing high-resolution, durable, and deformable conductive features suitable for wearable electronics, biointegrated sensors, and soft-robotic devices.
