Article Abstract

The increasing needs for new types of computing lie in the requirements in harsh environments. In this study, the successful development of a non-electrical neural network is presented that functions based on mechanical computing. By overcoming the challenges of low mechanical signal transmission efficiency and intricate layout design methodologies, a mechanical neural network based on bistable kirigami-based mechanical metamaterials have designed. In preliminary tests, the system exhibits high reliability in recognizing handwritten digits and proves operable in low-temperature environments. This work paves the way for a new, alternative computing system with broad applications in areas where electricity is not accessible. By integrating with the traditional electronic computers, the present system lays the foundation for a more diversified form of computing.

Origami frustration and its influence on energy landscapes of origami assemblies.

Harnessing instabilities of multicomponent multistable structural assemblies can potentially lead to scalable and reversible functionalities, which can be enhanced by exploring frustration. For instance, standard Kresling origami cells exhibit nontunable intrinsic energy landscapes determined by their geometry and material properties, limiting their adaptability after fabrication. To overcome this limitation, we introduce frustration to enable fine-tuning of the energy landscape and resulting deformation states.

Turbulence-induced vibrations pose substantial risks to aircraft structural integrity and flight stability, particularly in unmanned aerial vehicles (UAVs), where real-time impact monitoring and lightweight protection are critical. Here, we present a bioinspired twist-hyperbolic metamaterial (THM) integrated with a triboelectric nanogenerator (TENG) for simultaneously impact buffering and self-powered sensing. The THM-TENG protector exhibits tunable stiffness (40 to 4300 newtons per millimeter), ~70% impact energy absorption, and achieves a specific energy absorption of ~0.

Can artificial polymer materials exhibit the characteristic of "evolution" over time, similar to biological tissue? The limitations arise from their inherently static nature and the absence of dynamic structures. A strategy is proposed for designing polymer materials whose phases and mechanical properties can be continuously transformed and enhanced temporally. Specifically, the polymer phases experience a sequence of transitions involving generation, separation, and fusion.

Fiber-reinforced polymer composite mechanical metamaterials have emerged as promising candidates for multifunctional structural applications owing to their exceptional strength-to-weight ratios. However, achieving concurrent high stiffness, high strength, and large recoverable strain in such structures remains challenging due to inherent trade-offs between these properties. To address this limitation, a novel Möbius-inspired metamaterial through optimized fiber orientation design is developed.
