The present invention provides an inkjet adhesive comprising: one or more monofunctional monomers, each having a log D.sub.octano/water of 1.1 or higher; and one or more photoinitiators, wherein the inkjet adhesive is free from monomers having a log D.sub.octano/water of lower than 1.1. The inkjet adhesive is particularly formulated for use in a method of cold foil printing. The inkjet adhesive contains only low polarity monomers to provide the inkjet adhesive with the ideal balance of through and surface curing properties required for cold foil printing. The monofunctional monomers also provide the inkjet adhesive with good adhesion properties.

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.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for producing meander-line polarizers.
