Breaking Standard Laws of Origami

National Geographic:

A group of researchers led by Andres Arrieta, assistant professor of mechanical engineering at Purdue University, recently published a paper in Science about how earwigs’ wings work. When the team tried to model the unfolding mechanism using a traditional understanding of origami-like folding, it did not compute. The wings simply do not fold like typical well-known materials (think paper) at a single crease.
Instead, Arrieta’s team found that the wings work by possessing spring-like folds, which have two stable configurations. He likens them to slap bracelets, which can stably switch between two different orientations.
Julia Deiters, a researcher at Germany’s University of Duisburg-Essen who recently co-authored a study on the topic, says the wings are also stabilized by folds that are bended, as opposed to straight. These arrange mechanical forces in a way that enables the wings to “lock,” either when they are completely open or folded up.

Arrieta and others hope to use their insights into the wings’ mechanisms to create mimics in the future. “The wing gave us the recipe to make similar manmade materials,” he says. Such materials could be an invaluable tool with potential applications for making things like quick-assembly tents, portable solar panels, and compact electronics.

Origami Revolution on PBS

Haven't even sat down for time to watch this, yet; but the whole community has been buzzing about it.






According to Seth Friedman through "Google trends", searches are up 46% on origami since the NOVA airing.
