For such situations, this work synergizes permeable material identifications with carbon nanotube (CNT) film photo-thermoelectric (PTE) imagers in millimeter-wave (MMW)–visible light (Vis) bands and conventional Vis-computer vision (CV) approaches mainly used for analyzing outer shapes of 3D objects. Specifically, this work demonstrates multi-CV-driven non-destructive structural reconstruction techniques by ultrabroad MMW–Vis band multi-wavelength optical monitoring using the CNT film PTE imager. Here, the CNT film PTE imager ultra-broadly performs photo-detection operations over the existing sensors in comparable sensitivities with the conventional narrowband devices at each region. Thus, the above imager facilitates utilizing ultrabroadband multi-wavelength photo-irradiation as playing an essential role in the presenting non-destructive CV system. Following such device performances, the MMW–Vis multi-CV system with the CNT film PTE imager first speculates spatial locations of each part for targets by visual hull measurements, then restores their detailed structures by tomography approaches.

They indicate a visual signal when the temperature exceeds a predefined threshold. However, TTIs require a manual process of checking each label individually, making their applications time and cost-intensive. Radio frequency identification (RFID) tags can streamline the process with data readily available in digital format. Challenges of RFID-based temperature sensors are the need for a battery and incompatibility with standard readers. In this study, thermoresponsive composites are developed based on acetylene black (AB) and poly(ethylene glycol) (PEG). By mixing two PEG binders having different molecular weights, the resulting composites function as thermal antifuses, irreversibly transitioning from a high resistance (HR) state to a low resistance (LR) state. The optimal composition detects a threshold temperature of ≈60 °C and shows a large HR/LR ratio of &gt;10³. Combining the antifuse based on this unique AB/PEG composite with an RFID tag with a tamper detection capability allows the fabrication of a battery-free, passive RFID temperature indicator equipped with a 1-bit non-volatile memory.

The jumping actuators are made of gelatin crosslinked with genipin and polyvinyl alcohol, ensuring resilience to stress during shell eversion. The shape and size of the shells are modeled and optimized for maximum jumping height resulting in jumpers with a diameter of 47 mm that can reach a jumping height of 361 mm. The edible jumpers can be loaded with additional nutritional components encapsulated by humidity-sensitive latches for automatic release.

Accurate design of the microfluidic device is important to allow recapitulation of key factors of a tumor and its microenvironment. Polydimethylsiloxane (PDMS) is widely used as material for microfluidics due to its favorable characteristics including low cost, suitability for rapid prototyping, optical transparency, and biocompatibility. However, the hydrophobic nature of PDMS complicates its use in microfluidic devices. Here, the characterization and application of an injection-molded functionalized PDMS fluidic insert for the commercially available Micronit system are described. The injection-molded PDMS has been modified with carboxyl groups to accommodate cell culture on its surface and to covalently bind proteins for long-lasting coating of the PDMS surface required for flow-conditions. Modification of PDMS does not change its favorable properties such as its high optical transparency and absence of auto-fluorescence.

Traditional organ-on-chip models often utilize rectangular cross-section channels, resulting in flat walls, sharp corners, and non-uniform wall shear stress profiles, which do not accurately mimic physiological conditions. Tubular channels with circular cross-sections provide a more in vivo-like geometry and result in a physiological uniform wall shear stress. Here, tubular channels fabricated using sugar 3D-printing are compared with rectangular channels made via stereolithography 3Dprinting. The results show that ECs from both blood and lymph vessels exhibit more uniform coverage and circumferential alignment in tubular channels than in rectangular channels. Unidirectional or bidirectional flow conditions align ECs parallel to the flow, overruling the circumferential alignment induced by curvature in tubular channels. Pulsatile flow enhances circumferential orientation in tubular channels, while alignment along the flow is maintained in rectangular channels. Additionally, EC orientation induced by flow impacts monocyte rolling velocities, crucial for understanding immune cell motility. This study underlines the importance of the combined effect of channel geometry and flow conditions in VoC models, and advocates for the continued development of advanced organ-on-chip systems that better replicate human physiology.</p>","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 7","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401994","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770392","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}
