Abstract: A method for producing flexible conductive printed circuit with a printed overcoat is disclosed. For example, the method includes forming conductive printed circuit lines on a flexible substrate, detecting locations on the flexible substrate where the conductive printed circuit lines are formed, and printing an overcoat over the conductive printed circuit lines at the locations that are detected on the flexible substrate, wherein the overcoat comprises a mixture of thermoplastic polyurethane (TPU) and a solvent having a viscosity of 1 centipoise to 2,000 centipoise to allow the mixture to be printed.

Abstract: A method is disclosed. For example, the method includes applying a clear coat layer on a substrate, drying the clear coat layer to form random microstructures in the clear coat layer, dispensing a printing fluid to print a graphical pattern on the clear coat layer, and generating a physical unclonable function (PUF) pattern by drying the printing fluid that fills the random microstructures formed in the clear coat layer.

Abstract: A printable flexible overcoat ink composition that can be digitally printed is disclosed. For example, the printable flexible overcoat ink composition includes a mixture of a thermoplastic polyurethane (TPU) and a solvent. The mixture is mixed to have a viscosity of 1 centipoise to 2,000 centipoise to allow the mixture to be digitally printed via an inkjet printhead or an aerosol jet printhead.
