Copper conductive inks are attracting immense interest given their augmenting contribution to the field of printed electronics, while its high-temperature conducting performance is indispensable. This study highlights a copper-based printable ink with high electrical conductivity at elevated temperatures for an increased operating life and capable of adhering to any geometric surface. The in situ formed copper-graphene printed conductor displays an electrical conductivity of 8 x 10(-5) S/m and maintains its stability up to 650 degrees C. Furthermore, high-temperature Cu sensor electronics are fabricated by using 3D printing, which paves the way for the resistance thermometer sensors and flexible electronics applications.
