The Nanostructured Origami? 3D Fabrication and Assembly method is used to create
three-dimensional (3D) nanosystems by exclusive use of 2D lithography tools. The
method consists of two steps. First, we nanopattern a membrane with functional
features: photonic, mechanical, electronic, chemical and/or biological components,
etc. During the same step, we define hinges, folding actuation, latching and
alignment mechanisms to be used in the next step. Subsequently, we activate the
membrane to fold it into the final 3D nanosystem with its components located and
interconnected as desired. We have studied experimentally and analytically, and
optimized several aspects of this technology: membrane materials, folding actuation
and dynamics, and alignment strategies. We have demonstrated a functioning
origami super-capacitor with energy density exceeding that of commercial devices.
We have also demonstrated that by using close-range interaction of nanomagnets
patterned on the membrane, we can achieve sub-100nm alignment between the
folded segments. Our results indicate that Nanostructured Origami enables accurate
and cost-effective manufacturing of 3D nanophotonic structures, for example
photonic crystals and non-crystals, as well as hybrids where integrated optical
components are combined with electronic, mechanical, and energy storage
elements.

George Barbastathis is Associate Professor of Mechanical Engineering at MIT. His
research is centered on the physics and engineering of 3D optical systems, in
particular volume holograms, photonic non-crystals, and mechanically
reconfigurable photonic crystals.
