However, preparing high‐performance ionogels with high conductivity and good mechanical strength remains challenging. Here, we report the development of a novel ionogel as a wearable device for monitoring the stimulus‐response behavior of aquatic animals. The integration of silver nanowires (AgNWs) endows the ionogel with good electrical conductivity (0.56 S m −1 ) and mechanical robustness (strain tolerance › 1400%). The ionic liquid (IL) makes the AgIL ionogel exhibit superior adhesion properties (84.6 kPa) across diverse substrates, including biological tissues (e.g., pig skin). Furthermore, this wearable electronic exhibits an ultralow detection limit (0.5%). The wearable electronics device consists of flexible AgIL ionogels as the sensing material, a microcontroller, a signal processing circuit, and a Bluetooth transceiver. Its electrical responsiveness and stable cyclic performance highlight its potential for wearable applications. This device can clearly and continuously monitor the regular or various stimuli‐induced movements of the gills, tail, and body of aquatic animals such as the Chinese sturgeon and bullfrog. Comparative studies with traditional rigid ionogels and hydrogels underscore the significant enhancements in flexibility, adhesion, and conductivity by our design.

Here, we report for the first time the use of Ce 2 Sn 2 O 7 /TiO 2 nanocomposites for ultra‐trace NH 3 detection at room temperature. The materials are synthesized via a facile hydrothermal route and systematically evaluated against common volatile organic compounds, including ethanol, acetone, methanol, n‐butanol, isopropanol, and triethanolamine. The Ce 2 Sn 2 O 7 /TiO 2 heterojunction demonstrated outstanding selectivity toward NH 3 , with the optimized CeTi2 sensor delivering an ultrahigh response of 83.8% to 100 ppm, a rapid response time of 12 and 5 s, and an exceptionally low detection limit of 2 ppb under ambient conditions (25°C). At 100°C, the prepared CeTi2 sensor displays a gas sensing response of 82.1% towards 100 ppm of NH 3 . Beyond sensitivity, the device exhibited excellent repeatability and long‐term stability, and ensured reliable operation under realistic environments. Mechanistic analysis revealed that the Ce 2 Sn 2 O 7 /TiO 2 interface induces strong surface band bending and remarkably accelerates charge transport and reversible adsorption–desorption dynamics. This work establishes Ce 2 Sn 2 O 7 /TiO 2 as a pioneering platform for ppt‐level NH 3 detection, offering a powerful combination of selectivity, stability, and energy‐efficient operation for environmental monitoring and industrial safety.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aiming to improve such situation, 3D tubular fabrics (A3,A4) are designed based on the thermosiphon mechanism with elastic hydrophobic BN/ZnO/PDMS@N/S‐6 and cotton yarns on the V‐bed flat knitting machine. Tubular structures are formed through arranging the elastic yarn to knit float stitches, while the cotton yarns to knit tuck and normal ones. The material and structure in the fabric contribute to the directional transport route of sweat on the surface synergistically. The property of sample A4 is optimal with results showing that a 5 µL droplet of artificial sweat traveled up to 2.6 cm longitudinally, which is 26 times farther than that laterally. Besides this, sample A4 also has excellent performance in moisture capture. Sample A4 showed the highest average moisture and liquid collection weight (8,225 mg) and Water Harvesting Rate (WHR = 2,056 mg/cm 2 h), approximately 2.6 times higher than that of sample A1. Headbands and wristbands made of sample A4 distributed 1 mL of artificial sweat across four tubular channels, expanding the diffusion area sixfold and achieving a maximum transport distance of 6 cm. After 25 times machine wash cycles, the directional transport performance remained still high, with 5 µL of artificial sweat moving 2.3 cm. Additionally, sample A4 behaved antibacterial activity against E. coli and S. aureus due to the presence of BN/ZnO/PDMS@N/S‐6. The design and performance of the 3D tubular fabrics are advantageous to the development and applications of moisture capture and transport.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"11 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147885884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hydrophobic characteristic prevents the ice/frost formation, and the slippery property accelerates the removal of supercooled liquid water. The light‐trapping effect from carbon nanotubes endows the film with superior non‐contact deicing ability via light irradiation. Furthermore, spatiotemporal control of frost crystal growth on a surface could be achieved via coordination of the strength of cooling and irradiation. Additionally, for the scenarios of sunlight absence, PIPCS exhibits an outstanding electrothermal deicing ability under low voltage. The above properties make PIPCS a promising all‐weather anti‐icing surface for passive anti‐icing and non‐contacting deicing in high‐altitude equipment and power transportation systems.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"11 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147895577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional sweat‐based AA sensors are hindered by complex, costly electrodes, and weakly hydrophobic substrates. In this work, we present a novel approach to sweat AA detection using simple, low‐cost, and highly hydrophilic sensors fabricated from carbon electrodes printed on flexible, delignified wood substrates. The electrodes are fabricated by screen‐printing carbon ink, resulting in low‐cost, simple structures. The wood substrates are prepared through a delignification process, which enhances their flexibility and hydrophilicity, enabling direct sweat permeability due to the natural alignment of vessel channels in the wood structure. These fabrication methods and unique substrate structures give the sensors a high sensitivity (0.032 µA·L·µmol −1 ), excellent selectivity, a low detection limit (10 µmol/L), and a wide linear range (10–1000 µmol/L), along with a fast response time, and outstanding stability against mechanical bending, temperature fluctuations, and long‐term storage. Selective detection of ascorbic acid is achieved even in the presence of common interfering substances such as glucose and dopamine. Moreover, the sensors have been successfully tested on real human skin, demonstrating their potential for reliable real‐time monitoring of AA levels.

As a wearable, integrable, and self‐powered sensing component, triboelectric yarn demonstrates significant potential in constructing comfortable, sensitive, and low‐power human‐machine interactive interfaces. However, yarn‐based triboelectric nanogenerators still suffer from low charge generation efficiency and rapid charge dissipation under dynamic conditions, which limit their practical application. Therefore, this study proposes a multi‐level structured triboelectric yarn designed with a synergistic combination of a conductive core, a charge trapping interface, and a microstructured friction surface, significantly enhancing charge generation, retention, and output stability. Experimental results demonstrate that the proposed triboelectric yarn exhibits a tenfold increase in open‐circuit voltage and a sixfold improvement in short‐circuit current compared to conventional yarns. Furthermore, the yarn can be woven into a smart textile for spatial pressure mapping and human‐machine interaction. A fabric keyboard array based on this yarn is integrated with a virtual interaction platform, enabling real‐time control of a virtual character through distinguishing commands based on pressing location and force intensity. This work provides an effective design strategy for high‐performance yarn‐based sensors and demonstrates their potential for immersive interactive applications in next‐generation wearable human‐machine systems.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147911483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A key challenge lies in developing coupling layers that combine sufficient rigidity for probe support with softness and adhesion to eliminate air gaps and maintain stable skin contact. Inspired by biological gradient structures, this rigid‐soft conflict was addressed by engineering a gradiently crosslinked polydimethylsiloxane (PDMS) coupling layer. The high‐modulus upper layer provided mechanical support for the probe, while the low‐modulus, adhesive bottom layer ensured conformal contact with skin. This gradient structure was achieved by pouring PDMS prepolymers onto a glass slide functionalized with N‐(2‐aminoethyl)‐3‐aminopropyltrimethoxysilane (AEAPS), which anchored platinum (Pt) catalyst near the surface. A diffusion‐driven Pt gradient resulted in a corresponding crosslinking density gradient upon immediate curing. Incorporating 3 vol.% tungsten and 25 vol.% aluminum oxide further optimized acoustic impedance (1.53 MRayl) to match skin and maintained high adhesion strengths (7.33 and 6.55 N m −1 ). This gradient PDMS layer enabled long‐term, stable coupling and high‐quality imaging of radial artery blood flow, advancing the field of wearable ultrasound diagnostics.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147882212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, a high‐performance piezoresistive pressure sensor based on PAN nanofiber films (PAN NFs) and MXene (Ti3C2Tx) is proposed. The realization of high sensitivity and wide sensing range is based on the microstructure of accordion‐like MXene and the macrostructure of fluffy porous blowing spinning PAN nanofibers, which exhibits a high sensitivity of 81.89 kPa−1 over a wide sensing range of 0.83–38.13 kPa and the dynamic responses to external pressures can reach 98.73 kPa. The pressure sensors based on skin surface‐like 3D patterned interwoven structure are used for health monitoring and tiny pressure detecting. Moreover, the application in human–machine interface is demonstrated.
