Origami Inspires Research Into Materials That Self-Assemble When Exposed to Light

The U.S. National Science Foundation is funding research into creating two-dimensional (2D) materials capable of folding themselves into three-dimensional (3D) objects when exposed to light.
North Carolina State University (NCSU), which in earlier research detailed a way to convert 2D patterns into 3D objects using only light, will lead the initiative. "We're pulling together a diverse team of designers, engineers, and mathematicians to advance our understanding of how to manipulate photoresponsive materials," says NCSU professor Jan Genzer.
The methods are inspired by origami. The multi-university team will use experiments and computational models to evaluate the folding process in order to develop new multi-functional 3D structures that can form rapidly while retaining precise control over their shape. The patterns will be based on 2D materials, and the process should be compatible with high-throughput patterning techniques, such as roll-to-roll patterning used in electronics.
"Ultimately, we hope to develop new techniques that have applications ranging from electronics to high-volume manufacturing to the delivery of humanitarian relief," Genzer says.
