Abstract
The advancement of fibre electronics is crucial for developing wearable smart textiles. However, traditional single-function fibres are typically limited to basic sensing and data collection capabilities, lacking effective computational and multimodal signal processing abilities, thus significantly restricting their potential in human activity recognition. Recently, Gupta et al. introduced an innovative single-fibre computer embedding eight microelectronic devices, integrating sensing, communication, and computation into a single fibre. Establishing a distributed cooperative fibre network substantially enhanced human activity recognition accuracy from 67% (single-fibre scenario) to 95%. This novel approach effectively addresses the limitations of conventional smart fibres, paving the way for multi-point sensing, edge-based inference, and real-time human–computer interactions in future intelligent textiles.
1. Introduction
The development of fibre-based electronics is indispensable to the advancement of intelligent textiles, serving as a foundational bridge that connects conventional fabrics with next-generation wearable electronic systems [1, 2]. However, one of the most significant limitations of current smart textiles lies in the restricted functionality of individual fibre units, which typically lack embedded computational capabilities [3, 4]. This makes performing localized processing and real-time interpretation of complex biosignals difficult. Additionally, the spatial resolution of signal acquisition is often insufficient, limiting the system's ability to accurately and comprehensively capture full-body motion dynamics. Moreover, communication between sensing nodes generally relies on rigid wiring, which reduces the textile's mechanical flexibility and impedes efficient signal transmission, collaborative sensing, and distributed data fusion—all of which are essential for scalable, high-performance systems [5–7]. Compounding these challenges, most existing innovative textile platforms lack the architectural flexibility and scalability required to integrate and analyse multimodal inputs, such as mechanical, optical, and electrophysiological signals. Such limitations critically hinder the adaptability, intelligence, and practical deployment of next-generation smart textiles across diverse application scenarios.
To overcome these challenges, significant breakthroughs in fibre-level system integration are required. The latest study published in Nature by Gupta et al. reported an autonomous programmable elastic fibre computer [8]. It transformed the computing architecture of conventional chips to the fibre scale, and effectively integrating multiple electronic components within a single fibre—thereby imparting capabilities for sensing, computing, storage, and wireless communication—is a crucial strategy for addressing the current limitations of fibre electronics. This approach paves the way for a paradigm shift in wearable electronics and intelligent textiles. The single-fibre computer integrates eight microdevices via helical wiring during thermal drawing, consolidating full computing, sensing, storage, and communication capabilities within a single elastic fibre. The resulting functional fibre exhibits over 60% stretchability and is machine-washable, offering high elasticity alongside embedded computational capabilities.

Direct Repair of the Crystal Structure and Coating Surface of Spent LiFePO4 Materials Enables Superfast Li-Ion Migration
The rapid accumulation of spent LiFePO4 (LFP) cathodes from retired lithium-ion batteries necessitates the development of effective and environmental-friendly recycling strategies. In this context, direct regeneration has emerged as a promising approach for reclaiming LFP cathode materials, offering a streamlined pathway to restore their electrochemical functionality. We report an integrated regeneration protocol that simultaneously repairs the degraded crystal structure and reconstructs the damaged carbon coating in spent LFP. The regenerated cathode material had superfast lithium-ion diffusion kinetics and a stable cathode–electrolyte interface, giving a remarkable rate capability with specific capacities of 122 mAh g−1 at 5C and 106 mAh g−1 at 10C (1C = 170 mA g−1). It also maintained capacities of 110.7 mAh g−1 (5C) and 84.1 mAh g−1 (10C) after 400 cycles. It could be used in harsh environments and could be stably cycled at subzero temperatures (−10 and −20 °C) and in solid-state electrolyte batteries. Life cycle assessment combined with economic evaluation using the EverBatt model reveals that this direct regeneration approach has high economic and environmental benefits.
Oxide Semiconductor for Advanced Memory Architectures: Atomic Layer Deposition, Key Requirement and Challenges
Oxide semiconductors (OSs), introduced by the Hosono group in the early 2000s, have evolved from display backplane materials to promising candidates for advanced memory and logic devices. The exceptionally low leakage current of OSs and compatibility with three-dimensional (3D) architectures have recently sparked renewed interest in their use in semiconductor applications. This review begins by exploring the unique material properties of OSs, which fundamentally originate from their distinct electronic band structure. Subsequently, we focus on atomic layer deposition (ALD), a core technique for growing excellent OS films, covering both basic and advanced processes compatible with 3D scaling. The basic surface reaction mechanisms—adsorption and reaction—and their roles in film growth are introduced. Furthermore, material design strategies, such as cation selection, crystallinity control, anion doping, and heterostructure engineering, are discussed. We also highlight challenges in memory applications, including contact resistance, hydrogen instability, and lack of p-type materials, and discuss the feasibility of ALD-grown OSs as potential solutions. Lastly, we provide an outlook on the role of ALD-grown OSs in memory technologies. This review bridges material fundamentals and device-level requirements, offering a comprehensive perspective on the potential of ALD-driven OSs for next-generation semiconductor memory devices.
Laser powder bed fusion of biodegradable Zn-4Cu alloy: Processing, microstructure and properties
Zn's natural degradability and biocompatibility make it a promising candidate for implants, however, its mechanical properties remain insufficient for bone applications. In this study, the performance of Zn was enhanced by developing Zn-Cu alloys via laser powder bed fusion (LPBF). Optimal LPBF parameters for forming stable tracks were achieved by adjusting laser power and scanning speed. Under optimized conditions of 100 W and 100 mm/s, high-density (99.58%) Zn-Cu alloys with improved hardness (68.2HV) and yield strength (160 MPa) were achieved. These improvements are attributed to solid solution strengthening, segregation strengthening, and grain refinement. The Zn-Cu alloys also demonstrated favorable degradation behavior, with a rate of 0.16 mm/year. This degradation is primarily driven by micro-galvanic corrosion between the CuZn5 phase and Zn matrix, along with refined grains and increased grain boundary density. This work demonstrates a viable strategy for fabricating Zn-based implants with enhanced structural integrity and mechanical performance via LPBF.
