Stretchable and Permeable Liquid Metal Micromeshes Featuring Strain-Insensitive Resistance Through In Situ Structural Transformations.

Gallium-based liquid metals hold promises for applications in stretchable electronics and beyond. However, these materials often encounter notable resistance increases during stretching and have negligible permeability to gases and liquids. This study presents an in situ structural transformation mechanism to create stretchable and permeable liquid metal micromeshes with strain-insensitive resistance.
