Piezoresistive metamaterials fabricated via 3D printing have gained increasing attention due to their high flexibility and stability, making them suitable for a wide range of applications. However, conventional isotropic and planar designs of these metamaterials restrict their sensing capabilities to uniaxial detection, significantly limiting practical utility. In this study, a 3D piezoresistive metamaterial inspired by the 3D structure of dendrites beneath human skin, achieving multidirectional and multifunctional sensing capabilities is presented by controlling the distribution of different lattice micro cell types. These anisotropic piezoresistive metamaterials can be successfully fabricated by one-step digital light processing (DLP) 3D printing. When integrated with augmented reality (AR) systems, these customizable metamaterials enable seamless object interaction workflows encompassing 3D spatial localization, capture, and recognition through real-time virtual feedback. Furthermore, a digital twin system is implemented to enhance real-time visual feedback in AR and deliver an immersive operating experience for the user. This synergistic combination of anisotropic design and one-step 3D printing establishes a novel paradigm for developing metamaterials with multifunctional, multiregional, and multidirectional sensing capabilities.

In this paper, the saturation of electrolytes on the mass transfer property of porous electrodes in non-aqueous lithium air batteries has been studied based on digital twin. Herein, we reconstruct the porous cathode based on X-ray micro-computed tomography (μct) and quantitatively analyze the pore size distribution, specific surface area, triple-phase interface area, conductivity and diffusion coefficient of reactants at varying filling degrees of the electrolyte. The results derived from digital twin provide insight into the gas–liquid two-phase mass transfer performance in the porous cathode with various degrees of electrolyte saturation and demonstrate that the optimum electrolyte saturation is 60%.Keywords:lithium air battery;saturation;X-ray micro-computed tomography;digital twin

High-temperature electrochemistry is widely used in many fields. However, real-time observations and an in-depth understanding of the inside evolution of this system from an experimental perspective remain limited because of harsh reaction conditions and multiphysics fields. Here, we tackled this challenge with a high-temperature electrolysis facility developed in-house. This facility permits in situ x-ray computer microtomography (μ-CT) for nondestructive and quantitative three-dimensional (3D) imaging. In an electrorefining system, the μ-CT probed the dynamic evolution of 3D morphology and components of electrodes (4D). Subsequently, this 4D process was visually presented via reconstructed images. The results monitor the efficiency of the process, explore the dynamic mechanisms, and even offer real-time optimization. This 4D analysis platform is notable for in-depth combinations of traditional electrochemistry with digital twin technologies owing to its multiscale visualization and high efficiency of data extraction.

Flexible wearable devices based on triboelectric nanogenerators (TENGs) can be used to track many parameters around the human body, including signals from motions, gestures, and contacts, to perform a variety of tasks. However, it is still a challenge to achieve wide working temperature and multi-parameter body motion sensing with TENG sensors. To address that, this work reports a facile 3D printing-based strategy for preparing functionalized heat-resistant TENG sensors. In detail, a printable heat-resistant ink and multiple 3D printing-based assembly methods are proposed. The as-fabricated ink, which could maintain up to 200 ℃, then serves as multiple components in the TENG sensors through patterning. Functionalized TENG sensors and human–machine interfaces are printed and subsequently networked on a human body to sense comprehensive motion information. The results indicate six typical motions can be recognized with 94.85% accuracy based on neural network algorithms. A simple digital twin for motion capture and trace tracking in virtual space is furthermore implemented. Combining the proposed TENG sensors with virtual reality (VR) platforms opens up a new road for human safety monitoring in high-temperature environments.
