Mechanical stimulation is critical in bone regeneration and significantly influences both EV secretion and cargo composition. Despite this, translating mechanically programmed EVs to clinically relevant doses remains a significant challenge. Most current scalable bioreactor systems has achieved high yields through high-density cell culture and fluid flow, yet they do not provide programmable or spatially consistent mechanical stimulation. In this study, an electrospun scaffold-enabled bioreactor was developed to integrate high-density three-dimensional macrophage culture with programmable cyclic stretching, enabling simultaneous EV scale-up and cargo programming. The interconnected fiber junction network transmits boundary-applied strain with enhanced spatial consistency, while the highly porous scaffold supports dense cell seeding and efficient EV release and collection. This approach increases EV yield by 13.8-fold compared to conventional two-dimensional culture. Fiber-mediated mechanical conditioning activates Piezo1-dependent Ca²⁺ signaling and integrin-associated mechanotransduction, promotes Yes-associated protein (YAP) nuclear translocation, and remodels EV cargo composition. The resulting mechanically stimulated EVs (ms-EVs) demonstrate concurrent pro-regenerative activities, including cellular rejuvenation, vascular repair, and osteogenic enhancement, and perform favorably compared to canonical interleukin-4 (IL-4)-polarized M2 macrophage-derived extracellular vesicles (M2-EVs). In aged rat femoral defects, ms-EV-functionalized scaffolds increase bone volume fraction by approximately 1.7-fold at 8 weeks, reduce p16⁺ senescent cells, and enhance CD31⁺ neovascularization. These findings establish electrospun scaffolds as scalable mechanobiological manufacturing substrates for the production of functionally programmed EV therapeutics.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"8 5","pages":"2113 - 2140"},"PeriodicalIF":22.6,"publicationDate":"2026-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148408661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a one-step, humidity-assisted electrospinning strategy that exploits the breath-figure effect to generate highly perforated ZnO/poly(lactic acid) nanofibers (HP-ZnO/PLA NFs) with ZnO preferentially exposed along pore walls is reported. Relative humidity (RH, 20%-60%) served as a direct process variable coupling textural porosity and Zn surface coverage: with increasing RH, the specific surface area increased from 0.64 to 10.92 m² g⁻¹, the Zn-covered surface atomic fraction increased from 24.2% to 44.9%, and the effective accessible ZnO area from 0.16 to 4.89 m² g⁻¹.

The loss of cardiomyocytes and structural damage to the ventricles following MI lead to cardiac dysfunction. Current myocardial repair scaffolds promote tissue regeneration by mimicking the natural structure of myocardial tissue, yet suffer from the limitation of focusing on a single dimension of repair, failing to address the complex pathological microenvironment after MI characterized by ischemia, inflammation, and stress mismatch. To overcome this, our study has developed a multiscale bionic fibrous scaffold. The scaffold combines directional freezing with electrospinning technology. While constructing oriented channels that mimic natural myocardial tissue, it embeds nanofibers into the channel walls to form synapse-like microstructures. In vivo and in vitro experiments demonstrate that this scaffold synergistically promotes myocardial repair through multiple mechanisms: providing mechanical support, promoting angiogenesis, and regulating macrophage polarization. It significantly improves cardiac ejection function and inhibits ventricular remodeling. This repair mechanism results from the nanofiber synapse structure activating downstream intracellular signaling networks through its integrin binding sites, thereby regulating cellular behavior. In summary, this study provides a novel strategy for developing myocardial repair materials that synergistically regulate multicellular tissues and match complex pathological microenvironments.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"8 5","pages":"2094 - 2112"},"PeriodicalIF":22.6,"publicationDate":"2026-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148710360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their performance at elevated temperatures is severely constrained by the thermal instability of polymer matrix. Herein, we demonstrate a novel aramid fiber-reinforced ceramic composite with a SiO₂ matrix as a thermally resistant radar stealth armor. To prevent fiber degradation during processing, the cold sintering process is employed to achieve densification of the SiO₂ matrix at merely 180 °C using Na₂SiO₃ as a transient liquid. Moreover, MXene modification of AF is introduced as an interphase to simultaneously enhance the interfacial shear strength and capability of microwave attenuation. By optimizing sintering conditions, the composite reinforced with a double layer of MXene-modified AF fabric exhibits a flexural strength of 166 MPa at room temperature and remains  stable up to 300 °C. Furthermore, the synergistic impact resistance from the ceramic matrix and AF fabric demonstrates excellent low-velocity ballistic shielding performance in the composite. Thanks to the capacitor-like structure and enhanced conduction loss of MXene interphase with increasing temperature, the composite realizes effective absorption bandwidth coverage throughout the X-band from room temperature to 300 °C.

However, traditional planar or simple 3D T-TENG structures often struggle to adapt efficiently to complex human motions, resulting in reduced electrical output and stability. In this study, we present a mechano-intelligent auxetic triboelectric textile (MIA-TENG) that integrates auxetic structures into the fabric to actively enhance contact and separation dynamics at the triboelectric interface.
