Novel Metal-Mesh Transparent Conductors for Flexible and Stretchable Electronics Applications

A unique way of making transparent conductors has been developed by embedding conductive inks into imprinted grooves to form a metal-mesh, which enables extremely high conductivity (0.03ohm/sq.) while still maintains high optical transparency (86 ^% ) and high flexibility. The embedded metal-mesh transparent conductors have been successfully applied to commercial touch panels, transparent electromagnetic shielding, heating films and thermotherapeutic patch for cancer healing. Recently the metal-mesh technology has been further extended to make stretchable transparent conductors and applied to stretchable electroluminescent devices.
