    Summary:
    A new type of foldable material has been designed that is versatile, tunable and self actuated. It can change size, volume and shape; it can fold flat to withstand the weight of an elephant without breaking, and pop right back up to prepare for the next task.

    Harvard researchers have designed a new type of foldable material that is versatile, tunable and self actuated. Here a single cell is folds according to its actuation.

    Imagine a house that could fit in a backpack or a wall that could become a window with the flick of a switch.

    Harvard researchers have designed a new type of foldable material that is versatile, tunable and self actuated. It can change size, volume and shape; it can fold flat to withstand the weight of an elephant without breaking, and pop right back up to prepare for the next task.

    The research was lead by Katia Bertoldi, the John L. Loeb Associate Professor of the Natural Sciences at the John A. Paulson School of Engineering and Applied Sciences (SEAS), James Weaver, Senior Research Scientist at the Wyss Institute for Biologically Inspired Engineering at Harvard University and Chuck Hoberman, of the Graduate School of Design. It is described in Nature Communications.

    "We've designed a three-dimensional, thin-walled structure that can be used to make foldable and reprogrammable objects of arbitrary architecture, whose shape, volume and stiffness can be dramatically altered and continuously tuned and controlled," said Johannes T. B. Overvelde, graduate student in Bertoldi's lab and first author of the paper.

    The structure is inspired by an origami technique called snapology, and is made from extruded cubes with 24 faces and 36 edges. Like origami, the cube can be folded along its edges to change shape. The team demonstrated, both theoretically and experimentally, that the cube can be deformed into many different shapes by folding certain edges, which act like hinges. The team embedded pneumatic actuators into the structure, which can be programmed to deform specific hinges, changing the cube's shape and size, and removing the need for external input.

    Weird science: New 3D material could herald shape-shifting buildings (VIDEO)
    The world of architecture might just be about to get a little more exciting – and malleable – with the advent of a new 3D shape-shifting material that can support thousands of pounds in weight. The development opens up the possibility of mutating buildings and pop-up emergency shelters, as the material can be instantly folded flat for easy transport before transforming at the flick of a switch into a multitude of shapes and sizes.

    According to the creators, the “metamaterial” is tunable in “shape, volume and stiffness,” and could even support the weight of a fully grown elephant. The material is based on a form of origami known as Snapology, a design concept that involves folding paper into 3D geometric shapes.

    The design has a range of potential applications, from future space homes to emergency tents and medical equipment.

    The interchangeable, cube-like structure consists of 24 faces and 36 edges with hinges that are manipulated remotely.

    It has yet to be given a really cool name, but a mesmerizing video showing the strange material ballooning up and then shrinking shows just how versatile it could be.r

    Great invention and possibly applicable in many ways. I think that's a great solution for earthquake areas, to create flexible structures
    that can sustain themselves in that way. I hope that, once these structures are in place, that the building company reads the manual well,
    securing the mechanism that folds, unfolds and sets it in motion, before people start living in them, or go to their jobs. For I think I would've
    to learn shapeshifting fast, when that's not so Laugh Better start now learning it, I think, in the present shapeshifting of our reality, hmmm?

    This invention might be one of many signs, at present, an expression of instinctual intuition, that our concept and experience of physicality and
    physical form is changing. Possibly us ending up in dimensions of formlessness as in no need of dense 3D matter. I assume that concept of shape-
    shifting realities isn't known to these designer scientists, for their research and design of this material would become useless in the blink of an eye.

    That's a good analysis B.B. Thubs Up I hadn't thought of that perspective.
