“…In this section, we report alternative fabrication methods that are more direct and do not start with a flat sheet of material. Instead, the intended final structure is designed using a computer-aided design (CAD) software and then realized through a few subsequent manufacturing steps, such as molding [83][84][85], winding [86], casting [87], CNC machining [88], or additive manufacturing [48,83,[89][90][91][92][93][94][95][96][97][98][99][100][101].…”

“…In molding methods, a mold resembling the Kresling column (a stack of KOSs) is first prepared using 3D printing (figure 7(a)). Next, uncured silicon resin or thermoplastic Polyurethane (TPU) is poured into the mold [83,96]. To ensure that a thin layer is formed, instead of a solid block of Kresling column, Li et al [83] employed spin casting, where the mold is spun at a rate of 10 rad s −1 , resulting in a homogeneous thin layer of silicon coating on the inner surfaces of the mold.…”

“…Using fused filament fabrication (FFF) [108], researchers were able to leverage the airtightness of the single-phase model for pneumatic applications, particularly in making artificial muscles [92], crawling robot actuators [99], ventilators [107], and energy absorbers [101]. In their simplest form, soft TPE [92,99], TPU [96], or Semiflex (Fenner Drivers, Inc.) [107] were used as 3D printing materials. For more complex structures designed for actuation and switching, the development of custom photopolymers (PPIA50-PEA50) [91], or shape memory polymers [90] is necessary for thermal actuation.…”

Structures inspired by the Kresling origami pattern have recently emerged as a foundation for building functional engineeringsystems with versatile characteristics that target niche applications spanning different technological fields. Their light weight,deployability, modularity, and customizability are a few of the key characteristics that continue to drive their implementationin robotics, aerospace structures, metamaterial and sensor design, switching, actuation, energy harvesting and absorption,and wireless communications, among many other examples. This work aims to perform a systematic review of the literatureto assess the potential of the Kresling origami springs as a structural component for engineering design keeping threeobjectives in mind: i) facilitating future research by summarizing and categorizing the current literature, ii) identifying the currentshortcomings and voids, and iii) proposing directions for future research to fill those voids.

“…With the strong nonlinearity [43], multi-stability [44] and inherent foldability [45], origami structures, exemplified by Kresling pattern [46], have been utilized in vibration systems [47] as well as other biological and aerospace applications ranging from nano-scale to mega-scale [45]. Variation of origami parameters leads to the shift of stable states [48,49] and provides them some interesting nonlinearities (e.g., quasi-zero stiffness [50] and hardening effect [51]).…”

This paper presents an electromagnetic energy harvester based on a unique nonlinear Kresling origami-inspired structure. By introducing the equilibrium shift phenomenon, reversible nonlinearity (i.e. mixed softening-hardening behavior) empowers the proposed harvester to work in a broad frequency band, confirmed by both simulation using a dynamic model and experimentation. The prototyped device can produce the open-circuit RMS voltage from 0.09 V to 0.20 V in the reversibly nonlinear response region in [6.19 Hz, 9.63 Hz] and a maximum output power of 0.4956 mW at a optimum load of 18.1 Ω under the excitation of 1.1 g. Moreover, detailed research further reveals that the design parameters of Kresling origami-inspired structure and electrical and mechanical loads influence reversible nonlinearity. Increasing the tip mass and γ0 in the M2 region of the design map strengthens the softening behavior, and enlarging the electrical load enhances the hardening behavior. The findings from this work deepen the understanding of the nonlinear behavior of Kresling origami, unveils the great potential of origami structure in energy harvesting and offers a new method to realize broadband vibration energy harvesters.

The study of multistable structures, particularly those that can twist, has attracted significant attention in recent years. This ability to transition between multiple stable geometries of these structures has paved the way for advances in diverse applications, such as morphing structures and robot actuation mechanisms. Conventional methods of designing and fabricating these structures often involve complex and resource‐intensive fabrication processes, which restrict their widespread adoption and limit their miniaturization. Here, we present a novel inflatable multistable twisting structure, based on helical folds of an elastic tube. Our fabrication approach utilizes directed mechanical instability as a method for a rapid fabrication, which is readily implemented at various length scales. We developed a theoretical model for the deformation of the bistable helical elements comprising the twisting structure, and compared it to experimental data. Furthermore, we demonstrate our fabrication methodology using a variety of polymers, including medical grade polymers, as well as various inner radii ranging from 5mm to 44μm and thicknesses of the tubes’ walls ranging from 250μm to 19μm .This article is protected by copyright.
