As the spatial resolution of the sensing nodes increases on the E-skin, it introduces challenges related to compact design and wiring. Herein, the design, fabrication, and characterization of an ultrathin, ultralow cost, highly compact, and flexible multimodal sensing hierarchical palmtop with 390 piezoresistive tactile pressure sensing nodes and 5 capacitive hydration sensing nodes are presented. Each tactile pressure sensing node consists of two 3D-printed Ag nanoparticle ink electrodes sandwiching a piezoresistive film. The hydration sensing nodes in contrast are capacitive type with 3D-printed Archimedean spiral Ag nanoparticle ink electrodes. Upon characterization, the pressure sensors exhibit a sensitivity of 1.188 kPa−1 and an impressive sensing range from 10 to 600 kPa. Meanwhile, the hydration sensing nodes display a sensitivity of 3.124 per percentage increase in hydration level, with a hydration sensing range of 25%–75%. Subsequently, machine learning is used to discriminate the region touched on the palmtop, object shapes, and hydration levels. Given its multifaceted capabilities, this palmtop is poised to find potential applications in various robotic contexts such as robotic hands, rehabilitation hand exoskeletons, and in the sphere of augmented reality.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 7","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801819","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}

Results showed that the CR clad sheet exhibited the highest tensile strength of 507 MPa. CR can fabricate the clad sheet with good interfacial bonding quality, devoid of defects such as pores and cracks. Moreover, CR introduced significant fine-grain strengthening and dislocation strengthening effects. After annealing, the Ti and Al layers underwent varying degrees of recovery and recrystallization, thereby improving the elongation of clad sheets, and attained optimal elongation at 773 K (28.3%). During annealing, the element diffusion layer thickness at the interface gradually increased with temperature, along with the enhancement of the metallurgical bonding effect, resulting in improved interfacial bonding strength. However, the mechanical properties of the clad sheet decreased at 823 K because of the production of TiAl3 intermetallic compounds.

The modification of SF with photoreactive groups has been used to create novel biomaterials that undergo a liquid-to-solid transition upon exposure to light, enabling precise control over structure formation, pore geometry, and degradation. This advancement of PF has been shown for the biofabrication of hydrogels, 3D scaffolds, and micro-patterned surfaces suitable for biomedical applications, including tissue scaffolds and bioelectronics. Herein, further improvement using a water-based ternary solvent of calcium chloride-ethanol-water (Ajisawa reagent (AR)) is presented, to dissolve PF, offering a sustainable alternative to previously used organic solvents. PF in AR is shown to be compatible with various light-based manufacturing techniques including soft lithography, photolithography, and 3D printing, enabling the fabrication of multiscale structures with high fidelity. The gels formed demonstrate excellent cytocompatibility, supporting cell adhesion and growth without additional coatings, making them ideal for regenerative medicine. The integration of conductive polymers, such as PEDOT:PSS as a 3D printable conducting gel opens possibilities for bioelectronics.

Four different types of mechanical tests were carried out: tensile, compressive, bending, and short-beam shear tests, and the fracture morphology of the specimens was observed and analyzed. The failure mechanisms of the materials under different processes were explored based on the stress analysis. It is found that in the materials manufactured by SVB process, voids can induce stress concentration effect, reduce the stress area and interlayer bonding force, and cracks are more prone to initiate and propagate around voids. These are all factors contributing to the reduction of bearing capacity and accelerating the failure process in the material. The void contents of laminates manufactured by DVB process and hot press process are extremely low, it is difficult for cracks to propagate within the material, and the composites can maintain excellent mechanical properties.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 7","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801827","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}

Vast differences in material properties, such as those between aluminum and stainless steel, cause significant compatibility issues. Their combination for higher performance is a compelling goal, but attempts are usually limited to nonadditive mechanical fastening. Wire-based additive for direct fusion has never been attempted, and only powder-based additive metal fusion manufacturing (AM) has shown any promise. Concentric radial deposition patterns are used in a wire-arc DED system to produce a layer-by-layer in situ bimetallic coupling between AA5356 and SS308L to address this. The additively generated mechanical bond is held together by residual pressure, created by different thermal expansion coefficients between the concentric material bands during cooling. This produces a purely additive yet viable mechanical joint with minimal metallurgical bonding. Destructive testing defines the integrity of the additively coupled unit, with the radial overlap sustaining 732.96 Nm in torsion, 34.17 kN in tension, and a maximum of 475 MPa in compression. Fracture modes confirm the importance of concentric residual loads in creating the mechanically viable joint. Interfacial characterization shows a 300× reduction in crack width for concentrically constrained interfaces with narrowed diffusion zones.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 7","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801828","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 multilayer functional film utilizes carbon nanotube film as the electrothermal substrate, incorporates cobalt (Co) for its photothermal properties and silicon dioxide (SiO2) for enhancing surface roughness and light trapping, thereby constructing a photothermal superhydrophobic surface, referred to as PCoSi-PCNT, and integrates capacitive icing sensors, temperature sensors, and humidity sensors. The deicing or anti-icing controller processes data to detect icing status and regulate the electrically heated deicing or anti-icing system. The results demonstrate that the photothermal superhydrophobicity of the multilayer functional film surface significantly delays icing. Notably, a 30 μL droplet was completely iced for 563 s at an ambient temperature of −15 °C, while the surface temperature rises to 67.3 °C at a light intensity of 100 mW cm−2. The deicing or anti-icing controller accurately detects changes in capacitance during the icing process of surface water droplets and activates electric heating in real time. With the continuous operation of the electric heating system, the surface temperature is consistently maintained between 42 and 55 °C.
