“…Apart from viscous-based sequencing, the growing material can be controlled via utilizing the different threshold pressures for the opening of straight and bent frusta (this concept is related to ideas explored by Peretz et al [27] and Melancon et al [28] ). For viscous-based sequencing, the fluidic pressure propagation determines the rate and order of opening of the frusta.…”

Growing soft materials which follow a three dimensional (3D) path in space are critical to applications such as search and rescue and minimally invasive surgery. Herein, a concept for a single‐input growing multi‐stable soft material, based on a constrained straw‐like structure is presented. This class of materials are capable of maneuvering and transforming their configuration by elongation while executing multiple turns. This is achieved by sequenced actuation of bi‐stable frusta with predefined constraints. Internal viscous flow and variations in the stability threshold of the individual cells enable sequencing and control of the robot's movement so as to follow a desired 3D path as the structure grows. A theoretical description of the shape and dynamics resulting from a particular set of constraints is derived. To validate the model and demonstrate the suggested concept, experiments of maneuvering in models of residential and biological environments are presented. In addition to performing complex 3D maneuvers, the tubular structure of these robots may also be used as a conduit to reach inaccessible regions, which is demonstrated experimentally.

“…1). We note that in contrast to recent metamaterials which exhibit sequential shape changes under monotonic driving [22][23][24][25][26], we require a sequential response under cyclic driving. This necessitates unit cells that memorize their previous state, interact with their neighbors, and break left-right symmetry.…”

Materials with an irreversible response to cyclic driving exhibit an evolving internal state which, in principle, encodes information on the driving history. Here we realize irreversible metamaterials that count mechanical driving cycles and store the result into easily interpretable internal states. We extend these designs to aperiodic metamaterials which are sensitive to the order of different driving magnitudes, and realize 'lock and key' metamaterials that only reach a specific state for a given target driving sequence. Our strategy is robust, scalable and extendable, and opens new routes towards smart sensing, soft robotics and mechanical information processing.

“…The advancement of additive manufacturing (AM) (i.e. 3D printing) technology has allowed the fabrication of complex multistable mechanical metamaterials [28,29], which is beyond the capability of traditional subtractive manufacturing methods. These 3D printing methods include macroscopic manufacturing technology and mesoscopic/microscopic manufacturing technology.…”

Multistable mechanical metamaterials are a type of mechanical metamaterials with special features, such as reusability, energy storage and absorption capabilities, rapid deformation, and amplified output forces. These metamaterials are usually realized by series and/or parallel of bistable units. They can exhibit multiple stable configurations under external loads and can be switched reversely among each other, thereby realizing the reusability of mechanical metamaterials and offering broad engineering applications. This paper reviews the latest research progress in the design strategy, manufacture and application of multistable mechanical metamaterials. We divide bistable structures into three categories based on their basic element types and provide the criterion of their bistability. Various manufacturing techniques to fabricate these multistable mechanical metamaterials are introduced, including mold casting, cutting, folding and three-dimensional/4D printing. Furthermore, the prospects of multistable mechanical metamaterials for applications in soft driving, mechanical computing, energy absorption and wave controlling are discussed. Finally, this paper highlights possible challenges and opportunities for future investigations. The review aims to provide insights into the research and development of multistable mechanical metamaterials.
