Abstract
Coating inkjet-printed traces of silver nanoparticles (AgNP) ink with a thin layer of eutectic gallium indium (EGaIn) increases the electrical conductivity and significantly improves tolerance to tensile strain. This enhancement is achieved through a room temperature 'sintering' process in which the liquid-phase EGaIn alloy binds the AgNP particles to form a continuous conductive trace. These mechanically robust thin-film circuits are well suited for transfer to highly curved and non-developable 3D surfaces as well as skin and other soft deformable substrates.
