Photoresist-based patterning strategies have been standardized for decades since the invention of photolithography. However, there are still major challenges in the processing of certain functional structures. For example, ...
The ancient arts of origami, the art of paper-folding, and kirigami, the art of paper-cutting, have gained popularity in recent years among researchers building mechanical metamaterials. Folding and cutting 2D thin-film materials ...
Researchers have designed electromechanically reconfigurable ultrathin optical elements that can be controlled and programmed on a pixel-by-pixel level. These versatile metasurfaces could offer a new chip-based way to achieve ...
Researchers at North Carolina State University have developed materials that can be used to create structures capable of transforming into multiple different architectures. The researchers envision applications ranging from ...
A new approach to producing metamaterials draws on kirigami techniques to make three-dimensional, reconfigurable building blocks that can be used to create complex, dynamic structures. Because the design approach is modular, ...
Curved imagers that can adjust their shape could have many valuable applications, for instance, aiding the development of more advanced medical imaging tools and cameras. Most existing flexible curvy imagers, however, are ...
Azobenzene functionalized liquid crystalline polymers are considered "smart" materials owing to their programmable shape transformations under various external stimuli (i.e., thermal, chemical, and photomechanical shape morphing). ...
A new technique that mimics the ancient Japanese art of kirigami may offer an easier way to fabricate complex 3D nanostructures for use in electronics, manufacturing and health care.
Multistable mechanical metamaterials are artificial materials whose microarchitecture offers more than two different stable configurations. Existing mechanical metamaterials rely on origami or kirigami-based designs with ...
Paper snowflakes, pop-up children's books and elaborate paper cards are of interest to more than just crafters. A team of Northwestern University engineers is using ideas taken from paper-folding practices to create a sophisticated ...
