Conventionally proposed 3D nanopatterning techniques have the capability to create various functions of 3D nanostructured materials that nature never provides. If it is possible to control and develop uniformly ordered 3D nano-architectures, we can build up new material properties. (e.g. photonic bandgap, negative refractive-index, and effective transport of energy and fluidics.) Furthermore, we can enhance mechanical, thermal, electrical, and optical properties of materials beyond intrinsic properties of bulk material. Our proximity-field nanopatterning (PnP) is a promising 3D nanofabrication technique with a specific structure design based on optics, simple materialization process, large pattern area, and high reproducibility. This technique can be applicable to many fields, including stretchable electronics, sensors, microfluidic devices, energy devices (thermoelectric and battery), and many others. 1. Low-dimensional carbon nanomaterials: Since the discovery of electrically conducting polymers (a discovery that led to the 2000 Nobel prize in chemistry), conjugated carbon based materials has been investigated for semiconducting, conducting, insulating and even light emitting layers of electronic and optoelectronic devices. The finding of fullerene in 1980s and carbon nanotube in early 1990s exploded the research field and recently found graphene filled the vacancy of 2D nanoelectronic material. The light-weight, flexibility, and supreme electronic and mechanical properties promise the usefulness of these materials to flexible electronics and mechanical and biological systems. 2. Three-dimensional nanostructured materials: The advent of nanoscience and technology is greatly indebted to the established techniques of micro/nanopatterning in past decades. Still, most of
