Abstract: Touch sensor circuits are used in touch screens for displays and graphical interfaces and may be, for example, resistive or capacitive touch sensor circuits. The touch sensor circuits may be manufactured using at least one catalytically active printable ink that may contain a plurality of radiation-curable binders, a plurality of coated electrically conductive nano-particles, a solvent, and may contain photo-initiators. The plurality of nanoparticles are coated by one of surfactants, polymers, or carbon. The ink is formulated to be used in a printing process such as a flexographic printing process or inkjet process to print complicated geometrics for microscopic patterns, particularly high resolution conductive patterns.
