“…Among the counterparts in the family of metamaterials, mechanical metamaterials are a unique type that possess distinctive mechanical properties such as negative Poisson's ratio, [4][5][6] negative stiffness, [9,10] negative compressibility, [11,12] tunable Young's modulus. [13,14] Over the past decade, researchers have extensively studied and developed various mechanical metamaterials in different dimensions and scales. In addition to the 3D structure in space, the development of active materials enables mechanical metamaterials to interact with external environmental conditions, such as heat, light, electricity, and magnetism, and realize dimensional switching from 2D to 3D, which is also called 4D metamaterials.…”

“…[2,3] Mechanical metamaterials create novel materials by optimizing the periodic geometric structure of cells, which can be freely selected and adjusted to meet specific requirements. As a result, mechanical metamaterials exhibit a variety of extraordinary mechanical characteristics, such as zero or negative Poisson's ratios, [4][5][6] vanishing shear modulus, [7,8] negative stiffness, [9,10] negative compressibility, [11,12] tunable Young's modulus, [13,14] singularly nonlinear behavior, [15,16] and customized topological microstructures, [17][18][19] all of which distinguish them from conventional counterparts. The ability to obtain programmable behavior through the interplay between material and structure leads mechanical metamaterials to the venue beyond the mechanical field, where studies have been reported on their active, adaptive, and actuating characteristics.…”

In recent years, mechanical metamaterials have shown good mechanical properties such as ultra‐lightness, programmable stiffness, and tunable Poisson’s ratio through clever structural design of microstructures. Micro/nanotechnology has been used to ensure mechanical metamaterials’ fabrication quality and performance for use as structural substrates in multifunctional applications. Mechanical metamaterials are intentionally engineered with periodic microstructures in diverse shapes, allowing for the creation of complex structural substrates. However, this sophisticated design poses significant challenges in the fabrication process, particularly at the micro/nanoscale level, where current technology hinders mechanical metamaterials’ performance improvement and function realization. This review explores the fabrication processes of mechanical metamaterials using micro/nanotechnology and showcase recent progress and future trends. Particular attention is given to recent development, challenges, and future trends in advanced fabrication technologies for mechanical metamaterials. This survey aims to explain why mechanical metamaterials have significant benefits and are well‐suited as structural substrates for multifunctional applications, what advanced fabrication technologies at the micro/nanoscale have been introduced to prepare mechanical metamaterials and how to overcome manufacturing technology bottlenecks of mechanical metamaterials in terms of synthesis, materials and design method.This article is protected by copyright.

Mechanical metamaterials enable the creation of structural materials with unprecedented mechanical properties. However, thus far, research on mechanical metamaterials has focused on passive mechanical metamaterials and the tunability of their mechanical properties. Deep integration of multifunctionality, sensing, electrical actuation, information processing, and advancing data-driven designs are grand challenges in the mechanical metamaterials community that could lead to truly intelligent mechanical metamaterials. In this perspective, we provide an overview of mechanical metamaterials within and beyond their classical mechanical functionalities. We discuss various aspects of data-driven approaches for inverse design and optimization of multifunctional mechanical metamaterials. Our aim is to provide new roadmaps for design and discovery of next-generation active and responsive mechanical metamaterials that can interact with the surrounding environment and adapt to various conditions while inheriting all outstanding mechanical features of classical mechanical metamaterials. Next, we deliberate the emerging mechanical metamaterials with specific functionalities to design informative and scientific intelligent devices. We highlight open challenges ahead of mechanical metamaterial systems at the component and integration levels and their transition into the domain of application beyond their mechanical capabilities.

“…[10][11][12] These materials, which are referred to as metamaterials, are engineered to exhibit properties that are derived from their architecture, rather than constituent materials. [13,14] Negative swelling ratio, [10] negative thermal expansion coefficient, [15] negative Poisson's ratio, [16] negative moduli, [17] anisotropic behavior, [18,19] reversible nonlinear deformability, [20,21] programmability, [22,23] and shape memorability [24] are some of the obtained mechanical properties.Modular metamaterials consist of rationally designed modules or unit cells linked to each other. In these materials, desired mechanical properties can be achieved by engineered deformation of the consisting modules.…”

Double‐Spirals Offer the Development of Preprogrammable Modular Metastructures

Metamaterials with adjustable, sometimes unusual properties offer advantages over conventional materials with predefined mechanical properties in many technological applications. A group of metamaterials, called modular metamaterials or metastructures, are developed through the arrangement of multiple, mostly similar building blocks. These modular structures can be assembled using prefabricated modules and reconfigured to promote efficiency and functionality. Herein, a novel modular metastructure is developed by taking advantage of the high compliance of preprogrammable double‐spirals. First, the mechanical behavior of a four‐module metastructure under tension, compression, rotation, and sliding is simulated using the finite‐element method. Then, 3D printing and mechanical testing are used to illustrate the tunable anisotropic and asymmetric behavior of the spiral‐based metastructures in practice. The results show the simple reconfiguration of the presented metastructure toward the desired functions. The mechanical behavior of single double‐spirals and the characteristics that can be achieved through their combinations make our modular metastructure suitable for various applications in robotics, aerospace, and medical engineering.
