Herein, we address this challenge with a hybrid metal–ceramic framework of Pt_xAu_1−x coated ZrO₂-Al₂O₃ nanofibers (Pt_xAu_1−x@ZANF), enabling flexible dual-functional temperature–pressure sensing up to 800 °C. Systematic studies on solid-state dewetting, nano-grain melting, and phase stability identified Au-rich Pt_0.15Au_0.85 as optimal: it retains a single face-centered cubic phase and low resistivity (&lt; 1 order of magnitude increase) after 2 h at 800 °C in air, outperforming pure Pt/Au and Pt-rich alloys (prone to phase separation/spheroidization). Laser-patterned electrodes on Pt_0.15Au_0.85@ZANF yield a dual-functional temperature–pressure sensor, which exhibits both high-temperature resistance and flexibility. The sensor exhibited a sensitivity range of 0.019 kPa⁻¹ to 0.054 kPa⁻¹ and demonstrated stability over 360 cycles (≥ 3 h) at 800 °C, far exceeding the maximum operating temperature of other reported temperature–pressure sensors (≤ 300 °C).

Conventional approaches, including screen printing, inkjet printing, and conductive-thread embroidery, enable the integration of conductive traces into garments but often suffer from limited patterning resolution, binder-related degradation, mechanical instability, and unreliable interfacing with electronic components. Here, we present a selective laser-assisted ablation method for directly defining conductive circuit traces on single-sided metallized fabrics (MFs) composed of woven, multi-stranded silver fiber yarns. This mask-free and chemical-free process enables rapid, digitally programmable patterning while preserving the structural integrity, flexibility, and breathability of the underlying textile. Importantly, localized laser heating simultaneously removes conductive fibers in selected regions and thermally fuses the exposed ends of adjacent silver yarns, thereby suppressing fraying and enhancing the mechanical robustness of the patterned circuit edges. Using a neodymium-doped yttrium aluminum garnet (Nd:YAG) laser tuned for high absorption by silver, controlled ablation at energy densities of 8–26.5 J·cm⁻² produced well-defined insulating regions without compromising the conductivity of neighboring traces. Surface and elemental analyses confirmed nearly complete silver removal, with residual silver content below 3% in the ablated areas. The resulting laser-ablated metallized fabric (LA-MF) exhibited low sheet resistance (approximately 2 mΩ/sq.), retained more than 94% of its initial conductivity after 10000 bending cycles, and maintained stable electrical performance after more than 20 machine-washing cycles. As a proof of concept, a 16-electrode electrical impedance tomography (EIT) array was patterned directly onto the MF and integrated into a compression garment for noninvasive lung-function monitoring. The textile electrodes enabled real-time impedance imaging, and an embedded convolutional neural network accurately classified respiratory states, including normal breathing and breath-hold conditions, even after repeated laundering. This laser-assisted patterning framework provides a robust, scalable, and manufacturing-compatible route for integrating high-performance circuit architectures directly into fabrics for wearable sensing, healthcare monitoring, and next-generation smart textile applications.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"8 6","pages":"2552 - 2577"},"PeriodicalIF":22.6,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42765-026-00761-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149310258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a self-adhesive lignocellulosic composite is designed directly from forestry residue <i>Eucommia ulmoides</i> bark (EUB), which is rich in <i>Eucommia ulmoides</i> gum (EUG) and lignin. The fabrication consists of a two-step process of in situ epoxidation and self-adhesive technique. In situ epoxidation transformed the intrinsic EUG into an excellent viscoelastic epoxidized EUG (EEUG). The self-adhesive technique relies on hydrogen bonding reinforcement promoted by pressure-assisted densification and thermal-assisted flow of EEUG, and further enhanced by epoxy ring-opening. This process converts the raw materials into a fully natural self-adhesive composite without any additional polymers. The demonstrated composite exhibits enhanced mechanical strength, notable flexibility, high hydrophobicity (contact angle at 104.55°), remarkable water resistance, improved thermal stability, and biodegradability (52.96% mass loss in 5 months). In addition, the life cycle assessment reveals a carbon emission factor of 3.28 kg CO₂ eq/kg, which can be reduced to 1.56 kg CO₂ eq/kg under renewable-energy production.

Herein, this study presents hierarchically structured zinc oxide (ZnO) clusters regulated by the matrix-regenerated cellulose fibrils (RCFs) template for efficient PDRC. A proposed ZnCl₂-mediated cellulose dissolution-regeneration strategy is developed to yield hydroxyl-rich RCFs with anchored Zn²⁺ ions, thereby facilitating the interfacial self-assembly of well-dispersed, flower-like ZnO clusters. Acting as efficient scattering centers, these hierarchical micro/nano architectures enhance light scattering via multiple internal reflections, endowing the ZnO/RCFs composites with an ultrahigh solar reflectivity (as high as 99.6% in the visible-light region to the near-infrared range) and ultra violet (UV) resistance (&gt; 240 h). Based on experimental results and theoretical simulations, a 'hierarchical-confined scattering' effect is proposed to clarify this mechanism. Combined with the high infrared emissivity (96.7%) in the mid-infrared region of the RCFs matrix, this synergy enables a remarkable daytime sub-ambient cooling of 11.2 °C. Energy consumption simulations further demonstrate its significant energy-saving potential across diverse climatic zones in China by reducing cooling demand.
