![]() It’s created by an insensitive director with a large ego. Most of the time, violence in American films is for spectacle. What purpose is there for a masked man to kill 20 college students in a log cabin in the forest? Why do I have to be scared every time I go into the woods? Why do we need to see another rape scene? Is any of this teaching us something new? I curse the directors for traumatizing their audience. My skin folds inward like a ball of slime into a bucket. My frame goes boneless and collapses inside of itself. My body has a reaction to the fourteenth splash of blood that squirts from a man’s brains in a Tarantino film. ![]() I’m not a fan of unwarranted violence in movies. An earwig’s wing joints are formed from layers of resilin, an elastic biopolymer that determines the spring type from its thickness and arrangement.Once Upon A Time … in a land of directors and writers, there lived a storyteller by the name of Matteo Garrone who spun a Tale of Tales. Sometimes, both rotational and extensional functions can be combined in the same joint. The important thing to remember about the earwig’s wing is that the elastic folds are able to operate as either rotational or extensional springs, which goes beyond origami principle: some shapes just can’t be created using standard folds. Their simulations showed that if the earwig’s wing operated with the classic origami principle of using straight, rigid folds with an angular sum of 360° at the intersections, it could only fold down to a third of its size. Inspired by this biological wing, we establish a spring origami model that broadens the folding design space of traditional origami and allows for the fabrication of precisely tunable, four-dimensional–printed objects with programmable bioinspired morphing functionalities.” We show that these notable functionalities arise from the protein-rich joints of the earwig wing, which work as extensional and rotational springs between facets. Such an unusual biological system displays incompatible folding patterns, remains open by a bistable locking mechanism during flight, and self-folds rapidly without muscular actuation. ![]() In contrast to well-known paper-folded objects, the wing of the earwig has an exquisite natural folding system that cannot be sufficiently described by current origami models. The abstract reads, “Origami enables folding of objects into a variety of shapes in arts, engineering, and biological systems. The object is 3D printed in its closed state. Studart, Professor for Complex Materials at ETH Zurich. Arrieta with the Programmable Structures Lab in the School of Mechanical Engineering at Purdue, and Professor André R. The researchers recently published a paper on their work, titled “ Bioinspired spring origami,” in the Science journal co-authors include Faber, Professor Andres F. “If, on the other hand, they simply refolded automatically, this would save a lot of hassle.” Faber, with ETH Zurich’s Department of Materials. “Once you’ve unfolded these things, it’s often impossible to fold them back to their original shape,” said Jakob A. Researchers also acknowledge far simpler uses for their invention, like foldable maps, package inserts, or tents. Potential applications for the 3D printed, self-folding origami elements include foldable electronics and solar sails for space travel, which could be packed in a small space and then opened to full size later, without the use of actuators or additional stabilizers. The 3D printed imitation of the earwig wing can be folded as compact as its natural counterpart. They have been studying the earwig’s elaborate wings by performing computer simulations, and developed an artificial structure which utilizes the same basic principle behind the wings. It’s no wonder that the team chose design principles that imitate the earwig’s wing to develop multifunctional, 3D printable origami structures. The wing can then completely fold into itself with a single click, no muscular actuation necessary. The compact way it retracts lets the earwig tunnel underground without risk of harming its wings, and when the wing is in an open, locked state, it stays stiff without having to use muscle power for stability. ![]() A team of researchers from ETH Zurich and Purdue University have taken their inspiration from the wing structure of an earwig, a strange-looking creature with a fascinating wingspan.Īn open earwig wing can expand 10 times larger than when it’s closed, which is one of the highest folding ratios in the entirety of the animal kingdom. Many scientists have been inspired by wings, be they bat, bird, or butterfly, in their 3D printing research projects.
