Electrohydrodynamic inkjet printing of reduced graphene oxide (RGO) is demonstrated to form complex geometric devices with high resolution (line width ≈ 5 mm). Both planar and highly curved surfaces (radius of curvature ≈ 60 mm) can be used as substrates. Demonstrations of counterfeit coin recognition using RGO patterns and all‐printed RGO transistors suggest substantial promise for applications in security and electronics.
