Get an original essay The active approach to bending is the leading term in lightweight design, kinetic and deployable structures today. Unlike previous approaches for deployable systems based on hinged connections, the active bending approach exploits the elastic deformation of the entire structure replacing the need for local hinges, which reduces the ecological footprint by pushing the material's capabilities to the limits and taking advantage of the pre-compression of the elements providing greater global stiffness and wider ranges of stability. This article will present further investigations into different types of deployable structures based on a series of cutting patterns on flat sheets of wood that manipulate their geometry after elastic deformation, this technique was inspired by the Japanese artistic approach Kirigami.1Keywords: Kirigami, active bending, deployable structures, architecture.IntroductionThe term deployable characterizes a system that can change shape so as to significantly change size. Examples of deployable structures are: tensile structures, bistable structures, some forms of Origami and scissor structures. Standard deployable structures are usually created by rotating rigid elements around their fixed hinges, (Example: scissor structures) which makes it somewhat heavy, which is why lightweight systems are usually connected to tensile structures and pneumatic structures, these systems can be differentiated by the direct relationship between strength and shape, resulting in efficient use of materials. In the last couple of years scientists and researchers have started to give more attention to lightweight systems with less waste and a low ecological footprint has led them to discover some models that can deform in size and shape due to their folding properties just by performing simple cuts into models without removing any parts allowing them to deform elastically. deform and sometimes expand up to 3 times its original length. This technique was introduced in the traditional Japanese Kirigami art which consists of creating multiple cuts on a flat paper allowing it to deform and expand. In essence, kirigami is a variant of origami, the art of folding paper. The words derive from the Japanese for cut (kiru), fold (oru) and paper (kami). The modern notion of origami as a recreational art and craft (avoiding all cuts in its purest form) took shape in the last century.2 Standard origami begins with a pristine sheet of paper, most often square, and proceeds exclusively adding folds: cutting or gluing is not allowed. In contrast, kirigami relies on both cutting and folding. The designs range from flat, symmetrical cut-out decorations like classroom snowflakes to elaborate designs that form 3D patterns similar to pop-up books. Kirigami, Japanese paper art, inspires twisting solar panels. Solar energy has become a wonderful source of renewable energy with the help of solar panels. But the technology is not yet infallible. The problem with flat3solar panels is that they need to stay facing the sun to produce electricity at an optimal rate, but the problem here is that the sun doesn't stay fixed in one place and moves across the sky. To solve this problem, scientists from the University of Michigan came up with the idea of ​​using the Japanese art Kirigami to develop:.
