We developed a continuous nanopattern manufacturing system that realizes a high-frequency vibrational indentation of a simple flat-edge rigid tool onto a horizontal-feeding polymer substrate with computer-based control. We first designed a process principle and its implementation modules, and subsequently constructed a system prototype. By controlling the tool vibration frequency and indenting force as well as the substrate feeding speed and stroke direction, we can create diverse nanopatterns with various periods and shapes including periodtunable nanogratings and multidimensional nanostructures. Such manufactured nanopatterns may be utilized in many potential applications involving precision machinery components, displays and light sources, sensors and actuators, and flexible electronics and photonics, all of which require tunable periods and shapes.
