The ability to manipulate materials in order to tailor and extend their properties to length scales spanning from the nanometer to the kilometer range remains a challenge in both fundamental and applied research. For example, several applications in energy harvesting and storage, health care, or distributed sensing, require complex nano-scale devices to be employed over macroscopic systems. This entails a controlled fabrication over drastically different length scales that is still difficult to achieve using conventional processing approaches. In this talk, I will present an original approach based on simple thermal drawing processes that enables the fabrication of nano-structured materials and composites with unprecedented aspect ratios. In particular, I will show how we were able to realize tens-of-meters long and flexible polymer fibers that integrate a prescribed assembly of conducting, semiconducting, insulating, and other functional materials into specific geometries and with micro- and nano-scopic feature sizes. Then, I will introduce the concept of one-dimensional distributed photodetecting devices and demonstrate how we can utilize the unique interplay between the materials, structures, and length scales of our processing approach to achieve unprecedented functionalities at the single fiber level as well as in fiber assemblies and fabrics. Finally, I will present a few examples to illustrate the wide range of new fundamental phenomena and potential applications that will be made possible by the rapidly evolving scientific field of multimaterial nano-stuctured fibers and composites.
