The shear strain induced by these waves at a frequency of ≈160 MHz, coupled with magnetoelastic effects, leads to domain magnetization oscillation, resulting in unique responses that are particularly pronounced near the coercive field. Experimental results reveal that the response of the sensor is highly sensitive to the angle between the applied magnetic field and the wave propagation direction, with profiles that can vary significantly depending on this angle, with some configurations resulting in practically opposite responses. A particularly relevant case arises when the magnetic field is aligned with the Love wave propagation direction. In this case, the sensor response shows mainly a monotonic increase with the magnetic field, except near the coercive field, where a sharp peak emerges and then abruptly collapses, resulting in a magnetic sensitivity of ≈5 Hz/nT (0.031 ppm nT−1). This high sensitivity near the coercive field opens the door to the development of high-performance sensors, simplifying electronics while leveraging the key advantages of SAW technology, including low power consumption, compact size, real-time response, and portability. A theoretical model is also discussed to further understand the underlying phenomena and optimize the design of next-generation devices, which hold significant potential for sensor applications across various fields.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 18","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202500746","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145101082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These sensors are of particular interest in healthcare, especially for monitoring physiological pressures such as intraocular, blood, bladder, and intracranial pressure (ICP), offering significant potential for clinical use. However, improving the sensitivity and in vivo performance of these sensors remains a key challenge. In this paper, a novel approach is introduced to enhance the sensitivity of wireless capacitive pressure sensors by utilizing a nanocomposite dielectric layer. Biocompatible zinc oxide (ZnO) nanoparticles are incorporated into styrene-ethylene-butylene-styrene (SEBS) at different concentrations to fabricate a nanocomposite pyramid-structured dielectric layer. Sensors with a 0.7%-ZnO (v/v) nanocomposite dielectric layer exhibit a 4.3-fold improvement in sensitivity compared to ones with a pure SEBS dielectric layer. The sensitivity of the fabricated sensors reaches a notably high value of 45 MHz mmHg⁻¹ within the pressure range of up to 25 mmHg. Additionally, a new pickup probe is developed that extends the wireless reading distance by 40% over conventional probes. Furthermore, in vivo studies are conducted, demonstrating reliable detection of ICP changes in murine models. This design enables wireless sensing without complex electronics, offering enhanced sensitivity, stability, and clinical potential.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 19","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a high-speed microscopy study of self-sustained, asymmetric oscillations in eutectic gallium–indium (EGaIn) microdroplets partially immersed in hydrochloric acid (HCl) solution is presented. Using a cost-effective smartphone-based imaging platform capable of 7680 frames per second, a pronounced temporal asymmetry in the oscillation cycle, consisting of a rapid 3 ms contraction driven by surface oxidation, followed by a 86 ms recovery governed by acid-mediated oxide dissolution at the triple-phase boundary, is uncovered. The system supports stable, high-frequency oscillations, sustaining up to 31 Hz for over 30 min, a performance that contrasts markedly with previously reported behavior in alkaline environments. As proof of concept, a Janus EGaIn-HCl droplet functioning as an autonomous optical modulator, producing tunable laser reflection and interference patterns without external input, is demonstrated. The oscillation frequency is readily tunable via HCl concentration, offering a strategy for environmentally regulated, redox-driven soft matter dynamics. These findings support the development of intelligent, self-regulating soft devices for chemical-to-mechanical energy conversion as well as adaptive photonics.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 19","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Annealing at temperatures of 80°C, 100°C, 120°C, and 140°C is assessed for its impact on material properties and physiological utility. Analytical techniques such as Differential Scanning Calorimetry (DSC), Fourier-Transform Infrared Spectroscopy (FTIR), and X-ray Diffraction (XRD) reveal increased crystallinity with higher annealing temperatures, peaking in β-phase content and crystallinity at 140°C. Scanning Electron Microscopy (SEM) shows that 140°C annealed scaffolds have enhanced lamellar structures, increased porosity, and maximum piezoelectric response. Mechanical tests indicate that 140°C annealing improved elastic modulus, tensile strength, and substrate stiffness, aligning these properties with physiological soft tissues. In vitro assessments in Schwann cells demonstrate favorable responses, with increased cell proliferation, contraction, and extracellular matrix attachment. Additionally, genes linked to extracellular matrix production, vascularization, and calcium signaling are upregulated. The foreign body response in C57BL/6 mice, evaluated through Hematoxylin and Eosin (H&E) and Picrosirius Red staining, shows no differences between scaffold groups, supporting the potential for future functional evaluation of the annealed group in tissue repair.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":" ","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12380390/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144938517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, purifying semiconducting CNTs using cellulose acetate (CA) as a surfactant in polar organic solvents is proposed that can tolerate environmental impurities such as water. Dispersion experiments with up to 1 v/v% water added to the polar organic solvent showed no significant deterioration in the purity and yield of the semiconducting CNTs. This process requires no dry hydrophobic solvents, in contrast to widely used extraction methods with conducting polymers. Controlling the solubility of CA with an ethyl lactate-tetrahydrofuran mixture helped differentiate between the colloidal stabilities of semiconducting and metallic CNTs and increased the purity of semiconducting CNTs. The semiconducting CNTs purified in this study demonstrated significant conductivity switching characteristics in electric double-layer transistors and large thermoelectric power factors used for thermal-electrical energy conversion.
