Herein, a novel silent speech decoding system is proposed, which employs a self-powered, low-cost, and conformable triboelectric-based E‑skin patch and a well-trained multi-layer convolutional neural network (CNN) model. We systematically characterize the structural principles and electrical performance of the E-skin patch. A comparative analysis of labial kinematics during vocalized and silent speech is also conducted, which demonstrates strong consistency in time-frequency domain characteristics. The utilized CNN model is trained across 15 lexical categories (200 samples per category), achieving a high accuracy of 98.75% and demonstrating excellent recognition performance. Furthermore, by integrating human-machine interaction (HMI) and virtual reality (VR) technologies, we develop three representative applications, including a real-time lip language visualization system, an orofacial-controlled \"Feeding Frenzy\" interactive game, and a VR communication platform with avatar dialogue.

Among various material systems, sulfide solid-state electrolytes (SEs) stand out as highly promising candidates owing to their exceptional ionic conductivity. Nevertheless, their extreme sensitivity to moisture results in the release of toxic H₂S and rapid structural degradation, which severely impedes their scalable manufacturing under ambient conditions. A bifunctional (3-mercaptopropyl)trimethoxysilane (MPTMS) coating strategy is herein presented to shield Li_5.5PS_4.5Cl_0.8Br_0.7 (LPSCBr) from moisture-induced degradation. The MPTMS layer forms a hydrophobic barrier of approximately 10 nm, which reduces H₂S emission by 93.0% after 35 min of exposure to 30% relative humidity, while maintaining 83.1% of the initial ionic conductivity (10.8 mS cm⁻¹). This approach tackles the core challenge associated with sulfide solid-state electrolytes: the realization of compatibility with controlled ambient air without sacrificing critical electrochemical properties. The modified electrolyte maintains a high ionic conductivity (&gt; 5.7 mS cm⁻¹) even after 10 h of air exposure. When applied in all-solid-state cells paired with LiNi_0.83Co_0.11Mn_0.06O₂ cathodes, it exhibits remarkable electrochemical performance, delivering a capacity retention of 84.6% after 1000 cycles. By enabling moisture-tolerant processing, MPTMS-modified LPSCBr SEs lay a solid foundation for the scalable, high-performance, and cost-effective production of ASSLBs.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"19 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02353-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149088612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To meet the demands of next-generation optoelectronic technologies for high performance, low cost, and portability, perovskite materials have emerged as highly promising light-absorbing materials due to their excellent optoelectronic properties, solution processability, and compositional flexibility. Recently, significant performance improvements in perovskite-based PDs have been achieved through various strategies. This review systematically summarizes and analyzes performance enhancement strategies for perovskite PDs. First, the fundamental working mechanisms and key performance parameters of PDs are introduced. Then, four core strategies for performance improvement are discussed in detail. In material preparation, methods for regulating the growth of high-quality light absorption layers are reviewed. In light management, technical approaches such as plasmonic effects, optical microcavities, and nanostructures for enhancing light-harvesting efficiency are summarized. In interface engineering, the impacts of energy level alignment, interface passivation, and charge transport layer optimization on device performance are analyzed. Concerning stability enhancement, the impacts of crystal growth control, additive engineering, and encapsulation technology on device performance are summarized and analyzed. The review further examines the representative applications of perovskite PDs. Finally, key challenges such as stability and large-area fabrication are discussed, along with perspectives on future development. This review aims not only to summarize the performance optimization strategies for perovskite PDs but also to provide a roadmap for their future development and exploration of applications in industrial manufacturing, daily life, and healthcare.</p>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"19 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02335-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149086516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional tactile sensors are limited to single-stimulus recognition and face fundamental challenges in scalability and functionality, as miniaturizing sensor pixels reduces baseline signal levels and degrades the SNR. This study presents a high-spatiotemporal and multimodal soft tactile interface for simultaneous perception of structural and thermal profiles, fabricated through a layered architecture enabled by additive manufacturing. The proposed interface incorporates a 3D-stacked capacitive pressure sensor that combines buried interdigitated capacitors and a parallel-plate capacitor, and a reduced graphene oxide based temperature sensor within the same pixel area. The 3D-stacked electrode architecture enhances baseline capacitance within a miniaturized pixel footprint, and a via-free, interlayered interconnection scheme resolves wiring complexity in the temperature sensor array. Each sensing layer operates through independent transduction mechanisms, enabling the simultaneous perception of structural and thermal profiles with minimal cross-interference. The fabricated multimodal array can spatially resolve both contact geometry and localized thermal distributions with high-spatiotemporal resolution. Furthermore, by applying a tactile scanning strategy in robotic perception, the platform successfully identifies geometric features and surface thermal profiles of target objects even under vision-limited conditions.

Here, a molecular engineering-assisted functionalization strategy is proposed: programming the coordination environment of nanocrystalline frameworks with monodentate carboxylic acid ligands of varied carbon chain lengths to construct a family of zirconium-based UiO-66 nanoporous frameworks that act as bilirubin-specific molecular capture traps. The experimental results and molecular dynamics simulations confirm that the newly engineered UiO-66 nanoporous framework rapidly enriched albumin-bound bilirubin through short-range van der Waals/electrostatic effects; the internal Zr–μ₃–OH sites then formed directional Zr–pyrrole coordination with the bilirubin tetrapyrrole core, whereas albumin was physically excluded by the narrow apertures of the engineered nanoporous framework (average 7.6 Å), breaking the “albumin barrier” without competitive displacement. Dense intrapore hydrogen-bonding networks and π–π stacking further strengthen bilirubin-specific complexation. The computed adsorption energy (ΔE_ads = – 3.7 eV) indicates spontaneous, diffusion-limited capture. In simulated blood experiments, the newly developed UiO-66 nanoporous framework achieves an ultrahigh bilirubin removal rate of ~ 97.9% with negligible albumin loss. Finally, clinical tests on plasma samples from ten liver failure patients revealed a 251% higher bilirubin removal capacity per unit mass than that of the commercial ion exchange resin (IER) within 3 h, while albumin leakage remained ≤ 2.58% (vs. ≥ 8.53% for commercial IER).
