Abstract: Disclosed are a flexible strain sensor and a method for manufacturing the same. A conductive line pattern is directly printed on a flexible substrate by jetting a printing material mixture of metal nanoparticles and CNTs at a high impact speed, and sandwiched between the flexible substrate and a flexible cover. The mixture is excited by aerodynamically controlling pumping timing and jetted onto the flexible substrate in an aerosolized state through a nozzle. The jetted mixture collides with the surface of the flexible substrate to create cracks, and then CNTs penetrate into the cracks and are mechanically locked with the flexible substrate. Subsequently, metal nanoparticles and CNTs are deposited thereon to a predetermined width and height, forming the conductive line pattern. This direct printing can be performed in a low pressure and at room temperature without using solvents or resins, thus no need for additional chemical post-treatment or heat treatment.

Abstract: In a method of printing a product, a plate gap can be at least partially concealed, and the presence of any trap lines can be minimized. The background of each impression can be printed to include a gradient region along the leading and trailing edges of the background adjacent to the plate gap. An overprint ink/layer can be printed over the plate gap and at least a portion of the background gradient regions. The overprint ink/layer can be printed to include gradient regions along the leading and trailing edges of the overprint. The overlapping gradient regions of the background and of the overprint soften or obscure the appearance of any trap lines that would otherwise be more prominent in the overlapping areas.
