Real-time magnetic noise sensing within skin tissues, especially through a quantum sensing technique known as T1 relaxometry, offers a promising approach for monitoring free radical activity. This technique uses fluorescent nanodiamonds (FNDs), whose optical properties change in response to magnetic fluctuations. To effectively deliver FNDs into the epidermis, we developed a dissolving microneedle (DMN) system composed of 10% polyvinylpyrrolidone and 3% hyaluronic acid. The DMNs exhibited strong FND fluorescence intensity concentrated at the microneedle tips (44%), optimizing their deposition within the epidermal layer. Histological analysis confirmed penetration depths of approximately 100–200 µm. To evaluate the sensing performance, T1 relaxometry measurements were conducted using gadolinium chloride solutions at the concentrations of 100 nm and 10 µm as surrogates for free radicals. Compared to the baseline, the mean T1 values decreased by 35% and 55% for 100 nm and 10 µm groups, respectively, demonstrating the system's sensitivity. Overall, our results highlight the potential of FND-loaded DMNs as a minimally invasive platform for high-resolution monitoring of oxidative stress and related biological processes in skin tissue.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"11 18","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.71117","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981492","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}

Among them, beryllium oxide (BeO) has high thermal conductivity (∼370 W/m·K at 300 K) and chemical stability makes it a promising candidate. However, the potential of BeO has been underexplored owing to the challenges in its nanoscale synthesis. In this study, we experimentally demonstrate for the first time the piezoelectric properties of BeO nanowires (NWs) and films. BeO NW arrays were synthesized via atomic layer deposition within anodic aluminum oxide templates. Structural and compositional analyses confirmed BeO NW formation, and piezoresponse force microscopy revealed an effective piezoelectric response with a longitudinal piezoelectric constant (d33) of 15.8 pm/V for NW, compared to 4.8 pm/V for thin films. Additionally, the BeO NW-based PENG achieved a maximum output voltage of ∼26.1 V and a maximum power density of ∼0.32 µW/cm2, which significantly exceed those of thin films (∼12.0 V and ∼0.09 µW/cm2, respectively) and are comparable to those of conventional wurtzite material-based systems.

Among various approaches, piezo-transmittance-based strain sensors offer fast response and environmental stability. However, achieving both high sensitivity and precise directional decoupling remains a significant challenge. While sensors relying on random microcracks exhibit high gauge factors, their stochastic nature hinders axis-specific sensing. On the other hand, engineered macroscopic structures like metamaterials provide structural predictability, yet they often suffer from reduced sensitivity and notable mechanical crosstalk between orthogonal axes. In this study, a direction-aware piezo-transmittance strain sensor was developed by engineering a controlled linear gap-opening mechanism in an aligned carbon nanotubes (CNTs)/polydimethylsiloxane (PDMS) composite. The uniform gap-opening structure overcomes the limitations of traditional crack-based sensors, achieving enhanced directionality, high sensitivity (gauge factor ≈ 283), low detection limit (0.03%), and excellent sensor-to-sensor uniformity (relative standard deviation < 12%). The sensor exhibits reliable performance over 17,621 strain cycles and enables precise multi-directional strain sensing through sensor arrays that quantitatively decouple orthogonal strain components. Finally, the developed sensor was integrated into wearable platforms, including attachment to joints and incorporation into stretchable exercise bands, demonstrating its potential for real-time human motion monitoring and for integration into wearable fitness and rehabilitation devices.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"11 18","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.71130","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981411","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 contrast, the c-In2O3/MgO TFT demonstrates well-defined anticlockwise hysteresis with a large memory window of 17 V, a high ION/IOFF ratio of 108, and threshold voltage of 0 V. The interlayer passivates oxygen vacancies in c-In2O3, thereby reducing the carrier concentration. Meanwhile, mobile protons (H+) in the GI can contribute to the hysteresis through proton-related interfacial polarization, consistent with the capacitance response. The device successfully emulates key biological synaptic functions, including excitatory and inhibitory postsynaptic current (EPSC/IPSC), paired-pulse facilitation (PPF), short-term plasticity (STP), and long-term plasticity (LTP).

This review shows that this limitation is not incidental, but arises from tightly coupled, multiscale constraints that preclude monotonic scaling of DIW processes. We develop a unified framework that identifies six interacting sources of limitation, spanning nozzle geometry, flow-rate and deposition dynamics, ink rheology, interlayer bonding, filament and structural mechanics, and system-level control and environmental effects. We treat material classes as boundary conditions for scalability and formulate scaling relationships that connect throughput, recovery kinetics, bonding windows, filament stability, and attainable part-size-to-feature-size ratios.
