“…A potential approach to overcome this limitation is to take a multimaterial design strategy with both soft and rigid components, which, for example, could increase the load-bearing capacity of kirigami metamaterials for engineering applications such as impact energy absorption. [14] Moreover, symmetry-broken kirigami can be made responsive to multiphysical stimuli through the integration of active materials, such as shape memory polymers, [63] hydrogels, [64,65] and dielectric elastomers. [66] While the concluding demonstrations of our work show how to harness slit symmetry breaking to tailor anisotropic deployment in bistable kirigami, our strategy holds generality and can also be extended to other kirigami patterns [31,67] as well as other types of metamaterials [41,68] and metasurfaces.…”

Shape morphing in bistable kirigami enables remarkable functionalities appealing to a diverse range of applications across the spectrum of length scale. At the core of their shape shifting lies the architecture of their repeating unit, where highly deformable slits and quasi‐rigid rotating units often exhibit multiple symmetries that confers isotropic deployment obeying uniform scaling transformation. In this work, symmetry breaking in bistable kirigami is investigated to access geometric frustration and anisotropic morphing, enabling arbitrarily scaled deployment in planar and spatial bistable domains. With an analysis on their symmetry properties complemented by a systematic investigation integrating semi‐analytical derivations, numerical simulations, and experiments on elastic kirigami sheets, this work unveils the fundamental relations between slit symmetry, geometric frustration, and anisotropic bistable deployment. Furthermore, asymmetric kirigami units are leveraged in planar and flat‐to‐3D demonstrations to showcase the pivotal role of shear deformation in achieving target shapes and functions so far unattainable with uniformly stretchable kirigami. The insights provided in this work unveil the role of slit symmetry breaking in controlling the anisotropic bistable deployment of soft kirigami metamaterials, enriching the range of achievable functionalities for applications spanning deployable space structures, wearable technologies, and soft machines.This article is protected by copyright.

Friction is an ever-present force in our lives, affecting the interaction between objects in numerous ways. The common hypothesis of frictionless contact between a foreign rigid object (needle) and a target material during puncturing leads to a constant penetration force. However, experimental observations reveal a linear increase in penetration force as the needle tip delves deeper. This force increment arises from the interplay of friction and adhesion at needle-solid interface. The present work provides an insight into the measure of friction and adhesion quasi-static characteristics at the needle-solid interface through puncture experiments. To this end, an axisymmetric hyperelastic model is presented to describe the expansion of a cavity under the contact pressure of the penetrating needle. In addition, the competing mechanisms of cavity expansion and mode I cracking during needle penetration in a soft solid are discussed.
