Here, we report flexible laser-induced graphene (LIG) bioelectronics that achieve mechanical compatibility with soft tissues and enable multimodal recording across species. Through optimized fabrication and multistep surface modification, we developed bilateral LIG (BiL-LIG) biosensors with an extended working range (up to 40% improvement compared with single-layer LIG) and high sensitivity at high strain (gauge factor of 3.77), as well as interfacially engineered LIG (IntE-LIG) neural electrode arrays exhibiting high signal fidelity, markedly reduced impedance (up to 98.5% reduction), and long-term in vivo stability (maintained signal quality for up to 4 weeks). The BiL-LIG biosensors captured subtle movements and vital physiological signals, including heart rate and respiration, in human volunteers, non-human primates, and rodents, while the IntE-LIG electrodes enabled stable long-term neural recordings in vivo. Integrating these devices yielded a flexible physiological-electrophysiological monitoring system (PEMS) validated in a mouse model of epilepsy, which simultaneously tracked heart rate and neural activity during seizures and pharmacological intervention. This work establishes a scalable platform for multimodal bioelectronic integration, providing new opportunities for precise seizure detection and for advancing research into neuropsychiatric disorders and brain function.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"70 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147755199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we employed a sacrificial template method combined with solvothermal induction to construct a GDL with a rich pore structure and multiscale rough structure. This enhancement reinforces the three-phase interface on the GDE, accelerates CO₂ mass transfer at the catalyst surface, and enhances the GDE's durability under high cathodic potentials and alkaline conditions. The catalytic performance of the nanostructured copper catalyst was evaluated, showing stable electroreduction for up to 69 h at a constant current density of 200 mA cm⁻². At a potential of −2.0 V(vs. RHE), no flooding still occurs in the system, demonstrating superior selectivity and voltage stability compared with commercial GDLs. Furthermore, real-time wettability changes of the electrolyte on the GDL surface were investigated using electrowetting and durability tests, revealing the flooding mechanism of the GDE during the catalytic process. This work is expected to provide guidance for the design and industrial implementation of ECO₂RR technologies.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"60 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147755177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, this study proposes a heterodimensional interface engineering strategy to fabricate dual-functional phase change regulator capable of synergistically achieving efficient thermal management and microwave dissipation. By integrating paraffin wax (PW) with a robust three-dimensional polypyrrole (PPy) network decorated with vertically aligned MoS₂ nanosheets, the resulting PW-PPy@MoS₂ phase change regulator achieves a high phase change enthalpy of 108.2 J·g⁻¹. In device-level testing, PW-PPy@MoS₂ significantly reduces the peak temperature of high-power chips and contributes to extended device longevity. Electromagnetically, PW-PPy@MoS₂ exhibits outstanding microwave absorption, with a minimum reflection loss of -73.18 dB and a broadband absorption of 6.56 GHz, originating from its well-designed hierarchical architecture. 3D PPy@MoS₂ conductive network and heterogeneous interfaces synergistically optimize impedance matching, while simultaneously activating a collaborative dissipation mechanism dominated by interfacial polarization, supplemented by dipole relaxation, conductive loss, and multiple scattering. Simulations and experiments further confirm its promising potential in radar cross-section reduction and wireless communication signal shielding. This work provides a promising heterodimensional material design solution to the integrated thermal-electromagnetic management challenges in high-power integrated electronics.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"60 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147755200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the <jats:italic>x</jats:italic> value increases, configurational entropy rises, inducing phase competition and stabilizing the superrelaxor state at room temperature. The HE environment disrupts long‐range ferroelectric order and promotes random octahedral tilting.

Unfortunately, their insufficient compressive strength (often &lt; 0.5 MPa) and high flammability limit their practical applications. To bridge this gap, we here report a bottom-up biomimetic mineralization strategy to prepare biobased aerogel (SiB@CC) by impregnating chitin/chitosan aerogels with sodium silicate and borax, followed by freeze-drying and thermal cross-linking. The SiB@CC aerogels exhibit high compressive strength (up to 2.25 MPa) and exceptional energy absorption. The aerogel can withstand 81 000 times of its own weight without failure, and its energy absorption efficiency is superior to that of most polymers, metals, and ceramics. Benefiting from the ability to form a robust organic-inorganic char layer, the SiB@CC aerogels exhibit excellent fire resistance and cannot be ignited, with a limiting oxygen index value exceeding 90%. Moreover, the aerogel shows exceptionally high-temperature thermal insulation, as evidenced by a backside temperature of only 130^°C after 600 s continuous exposure to ∼1300^°C flame. This work offers a promising biomimetic approach for preparing bio-based aerogels combining high-strength, fire-resistant, and super thermal insulation, which is expected to find great potential for sustainable high-temperature thermal insulation.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"117 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Breath sensors targeting ammonia (NH₃) have shown significant potential for early CKD diagnosis due to their excellent ability to analyze human breath. However, the rational design of the functional sensing layer—particularly concerning active sites and adhesion forces—remains a considerable challenge. This study developed a multifunctional wearable sensor based on polyaniline (PANI) featuring a bionic rose micro-dome structure, fabricated via a modified in situ growth method. Owing to the superhydrophobic microstructured sensing layer with a contact angle of 108.6°, the sensor exhibits excellent humidity resistance and an expanded NH₃ contact area. The sensor demonstrates a remarkable 97.3% improvement in response to 100 ppm NH₃, a low detection limit of 0.1 ppm, and high moisture resistance under 80% relative humidity. Clinical tests reveal its potential for breath monitoring in CKD patients, effectively distinguishing between varying disease stages with an accuracy of up to 91%. Furthermore, due to the specialized nanostructure modification providing strong adhesion, the sensor exhibits a pressure sensitivity of 0.7126 kPa⁻¹ and a broad detection range of 0–35 000 Pa, thereby enabling precise monitoring of subtle human movements and gestures. This research proposes a novel strategy for designing high-performance, multifunctional flexible sensors based on PANI microstructures. This approach not only enhances the detection capability of trace NH₃ in complex humidity environments but also offers an innovative solution for the early screening and clinical monitoring of CKD, as well as for the development of multifunctional health monitoring systems.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"26 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147753460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we report a novel patch repair strategy that in situ embeds highly conductive VN patches into the Na₃V₂(PO₄)₃ matrix, generating dual-functional Na⁺ storage pathways. The VN phase serves as a dynamic reservoir that unlocks interface adsorption/desorption storage, while its strong electronic coupling with the NVP host enhances bulk diffusion, facilitating fast Na⁺ kinetics in both plateau and slope regions. The optimal electrode delivers a specific capacity of 145.4 mAh g⁻¹ at 0.1 C, exceeding the theoretical capacity of Na₃V₂(PO₄)₃ by 123.6%, while maintaining over 95% capacity retention after 5000 cycles at 20 C. A pouch cell achieves an energy density of 423.05 Wh kg⁻¹ and 98.56% capacity retention over 500 cycles at 2 C, along with reliable low-temperature performance. More significantly, in situ XRD analysis corroborates a reduced diffusion barrier in the plateau region induced by VN, and unveils for the first time a continuous solid-solution reaction in the slope region, offering direct visualization of the non-diffusion-controlled storage mechanism.
