Traditional strain sensors in SHM often face limitations in sensitivity, durability, and scalability, particularly for large-area monitoring. In this work, these challenges are addressed by introducing a digitally fabricated strain sensor using additive 3D direct writing technology. The sensor uses a hybrid structure of stretchable carbon and silver materials to improve sensitivity and durability. It achieves dual-axis strain sensing by positioning carbon elements in both horizontal and vertical directions, enabling 2D strain mapping. A temperature sensor with nickel oxide nanoparticles provides temperature compensation, ensuring accurate strain measurements. To optimize performance, design parameters are fine-tuned, and comprehensive tests—including static, dynamic, and tensile strength evaluations are performed. The sensor, measuring 5 cm in length and 0.8 mm in width, reaches a maximum gauge factor of 2.45 at room temperature and shows minimal resistance change (0.01%) after 1000 bending cycles with a 5 mm radius. It detects small deformations with a resolution of 0.05%, and dynamic tests, such as earthquake simulations, verify its stability. Tensile testing, using a dynamic servohydraulic Material Testing System (MTS) frame for tension/compression, validates the accuracy of the sensor. This research advances SHM technology by offering a novel digital manufacturing approach for dual-axis strain sensing, demonstrating the potential of the sensor for continuous, low-cost, large-area monitoring.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 5","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143536051","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}

Hydrogels are frequently used to produce 3D models for tissue engineering, disease modeling, and high-throughput screenings (HTS). However, integrating 3D cultures into HTS workflows presents challenges, including automation compatibility and cost constraints. Addressing these challenges requires innovative approaches that enable miniaturization, automation, and cost reduction while maintaining experimental fidelity. The Droplet Microarray platform, based on hydrophilic-superhydrophobic surface patterning, facilitates the formation of nanoliter-hydrogel arrays containing cells or spheroids. This method allows dispensing of hundreds of nanoliter-hydrogel droplets with precise control over volume and cell density, reducing reagent consumption and offering high-throughput applications. Here, we demonstrate stable nanoliter-hydrogel arrays on a chip, enabling experimental procedures such as washing and medium immersion. Our approach demonstrates that spheroid-containing droplets can be gelled at any point of the experiment, allowing for the fixation of cell structures on the surface. The selective gelation of individual droplets enables spheroid sorting by stabilizing desired droplets while pooling the others. This method holds the potential for HTS and miniaturized workflows in 3D microenvironments, thereby advancing research in different fields such as cell, cell spheroid, or organoid screenings, drug screenings, and precision medicine.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 8","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401159","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840947","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}

Despite extensive studies, there remains a need for a deeper understanding of how particle size and loading specifically influence printability, especially in the nano range. This work aims to systematically evaluate the effects of SiO2 nanoparticle size (26–847 nm) and loading on printability within a polydimethylsiloxane (PDMS) matrix. For the single-layer printing process, which is influenced by the substrate properties, a 3D printing line analysis (3D-PLA) is developed to monitor the top and side views of printed lines. It is found that line width varies with ink composition and substrate, while the line height decreases with solvent evaporation, indicating a strong confinement effect from the substrate. For multilayer structures, dual-layer printing analysis (DLPA) is utilized to evaluate the printability. It is shown that DLPA is independent of the substrate and can be used to compare the printabilities from different inks. Both 3D-PLA and DLPA can be correlated to the rheological behavior of the ink through ink rheology analysis (IRA). Finally, this research defined the design space for DIW by benchmarking the minimum and maximum particle loadings for printable composite inks.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 8","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840674","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}

The sensor utilizes a high-impedance surface metamaterial, which functions as a perfect absorber at the resonant frequency. This sensor has a uniform water-soluble Mg film at the bottom coated with hydroxyapatite that degrades depending on the pH, and a periodic square split ring resonator metamaterial structure made on top of a lossy dielectric plate. The sensor detects the dissolution of the metamaterial due to soil pH conditions through the electromagnetic wave reflection response at GHz frequency. Because of the perfect absorbing characteristics, the influence of soil on the metamaterial's electromagnetic response is blocked, allowing for robust measurement regardless of soil type. By coating the Mg with hydroxyapatite, the difference between acidic (pH = 3.0) and neutral soils can be detected by the time difference by a factor of three in the reflectance change from 40% to 75% reflectance change, indicating a transition from absorptive to reflective of the metamaterial's response, at the resonant frequency of 4.12 GHz.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 8","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401134","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840675","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}

However, the aspect ratio of the printable structures, which is key for determining electrical properties, is typically determined by the wettability between printed ink and substrate. Higher aspect-ratio structures can only be achieved by multi-pass printing, with the consequent loss of fabrication throughput and increase in complexity. Here, these issues are addressed by using print-n-release, a method based on printing micro-electrodes on pre-stretched elastomeric substrates. Upon stress release, the liquid-printed electrodes shrink while increasing their aspect-ratio. As a result, their final shape can be tailored beyond the limitations imposed by wetting constraints, enabling intentional miniaturization by design. The principle and practical implementation of print-n-release are described, and show how electrodes with up to an 8 fold increase in aspect-ratio and a 4 fold reduction in sheet resistance can be produced in a single-pass compared to traditional printing methods. As a proof-of-concept, functional interdigitated electrodes that serve as sensors for drop volume and electrolyte concentration, delivering enhanced sensitivity and a reduced footprint not achievable with standard printing techniques are fabricated.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 7","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401641","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770532","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}

While recent advances in templated assembly methods enable high-throughput fabrication of multi-material active colloids, their limitations reduce the ability to construct flexibly linked colloidal systems, restricting their complexity, agility, and functionality. Here, templated assembly by selective removal (TASR) is leveraged to construct multicomponent colloidal microstructures that are connected with compliant DNA nanotube linkages. Polycarbonate heat (PCH) molding is employed to create high-surface-energy templates for improved polystyrene microsphere assembly via TASR. This increase in template surface energy improves microsphere assembly by more than 100-fold for two-sphere microstructures. An inverse relationship between microstructure complexity (i.e., the number of microspheres) and assembly yields is observed. PCH-assisted TASR is leveraged to construct larger colloidal structures containing up to 26 microspheres, multi-sphere microrotors, and structurally homogeneous populations of flexibly linked, two-sphere microswimmers that locomote in fluid environments. Real-time modification of a microswimmer is also demonstrated through nuclease-mediated degradation of the DNA linkages, highlighting the DNA-enabled reconfiguration and responsiveness capabilities of these microswimmers. These results establish PCH-assisted TASR as a versatile method for constructing flexibly linked, modular microrobots with controlled geometry, enhanced agility, and dynamic response.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 8","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401584","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840770","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}

Currently, these PEMMs are made with the selective layer on the inside of the hollow fiber.

This will lead to an increased surface area per fiber and enable the use of smaller mechanically stronger fibers, which further increases the surface area per membrane module. To prove that the concept of an outer-skinned PEMM is feasible, the dry-jet wet-spinning process is used to fabricate charged outer-skinned hollow fiber supports, and they are coated through the layer-by-layer self-assembly process to form a PEMM. Scanning electron microscopy images of the hollow fibers confirm the existence of an asymmetric structure with an outer skin, while fluorescence imaging confirms that the polyelectrolyte multilayer is located on the outside of the hollow fiber. Filtration experiments showed that the PEMMs exhibited nanofiltration properties similar to the conventional inner-skinned PEMMs. Overall, these membranes show a 3.8x increase in active membrane surface area to volume ratio compared to commercial PEMMs, clearly highlighting the benefits in terms of footprint.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 8","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401832","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840769","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}

This study develops a self-folding gelatin-based bilayer scaffold for trachea engineering exploiting the 4D bioprinting approach. Starting from a 2D flat configuration, upon hydration, the scaffold automatically forms a closed tubular structure. An analytical model, based on Timoshenko's beam thermostats, is developed and validated to predict the radius of curvature of the scaffold. The 4D bioprinted structure is tested with airway fibroblast, lung endothelial cells, and cartilage progenitor cells (CPCs) toward the development of a tissue-engineered trachea. Cells are seeded on the scaffold in its initial flat configuration, maintain their position after the scaffold actuation, and proliferate over or inside it. The ability of CPCs to differentiate toward mature cartilage is evaluated. Interestingly, real-time PCR reveals that differentiating CPCs on the 4D bioprinted scaffold promotes healthier cartilage formation, if compared with CPCs cultured on 2D static flat scaffold. Thus, CPCs can perceive scaffold folding and its final curvature and react to it, toward the formation of mature cartilage for the airway.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 6","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401210","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143639327","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}
