While recent wearable technologies can monitor behavioral and physiological changes associated with loneliness, existing solutions such as accelerometers and inclinometers often lack comfort and flexibility for long‐term monitoring. Smart textile systems offer a viable solution for continuous monitoring by integrating sensors and conductive materials into textiles. However, there remains a critical technological gap that no existing solution integrates multimodal textile‐based sensing specifically for loneliness detection. This review addresses that gap by providing a comprehensive review of smart textile technologies for monitoring loneliness in older people, highlighting sensing and design innovations to meet the needs of older users. Key behavioral patterns and physiological symptoms associated with loneliness are explored and suitable wearable sensing technologies, focusing on textile‐based solutions that combine comfort, flexibility, and monitoring accuracy, are reviewed. In addition, current advances in data collection, transmission, and analysis are examined for smart textile systems, exploring their potential and challenges in the field of elderly care. By identifying specific design requirements and challenges for monitoring loneliness in older people, this review lays the foundation for future research and development of proactive loneliness detection and intervention.","PeriodicalId":110,"journal":{"name":"Advanced Electronic Materials","volume":"30 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144850862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although hexagonal 2D MOFs generally display impressive electrical conductivity because of their dual in-plane (through bonds) and out-of-plane (through π-stacked ligands) charge transport pathways, notable differences between these two orthogonal conduction routes cause anisotropic conductivity and lower bulk conductivity. To address this issue, we have developed the first redox-complementary dual-ligand 2D MOF Cu3(HHTP)(HHTQ), featuring a π-donor hexahydroxytriphenylene (HHTP) ligand and a π-acceptor hexahydroxytricycloquinazoline (HHTQ) ligand located at alternate corners of the hexagons, which form either parallel HHTP and HHTQ stacks (AA stacking) or alternating HHTP/HHTQ stacks (AB stacking) along the c-axis. Regardless of the stacking pattern, Cu3(HHTP)(HHTQ) supports more effective out-of-plane conduction through either separate π-donor and π-acceptor stacks or alternating π-donor/acceptor stacks, while promoting in-plane conduction through the pushpull-like heteroleptic coordination network. As a result, Cu3(HHTP)(HHTQ) exhibits higher bulk conductivity (0.12 S/m at 295 K) than single-ligand MOFs Cu3(HHTP)2 (7.3 × 10−2 S/m) and Cu3(HHTQ)2 (5.9 × 10−4 S/m).

Here, an innovative percolation method utilizing a time‐efficient shortest‐path algorithm is introduced, effectively addressing the arbitrariness in nanowire networks to achieve more realistic conductivity modeling. By applying the percolation framework to arbitrary nanowire assemblies, universalized cluster parameters within the shortest paths are indentified, highlighting the most relevant conductive paths rather than exhaustively examining all nanowire connections. This approach is employed to analyze the two‐step conductivity behavior observed in random ZnO nanowire films. The results indicate that tunneling conduction is the primary mechanism below the percolation threshold, while percolative conductivity becomes dominant beyond this threshold. This model precisely calculates tunneling distances within universalized networks, offering accurate conductivity modeling based on nanowire spacing, which previous models have not fully captured. Furthermore, at low nanowire concentrations, charge transport is confined to a single lowest‐energy barrier path, as evidenced through both numerical and experimental methods. This comprehensive approach integrates theoretical models and experimental applications to enhance the practical use of random nanowire assemblies in real‐world applications. It also enables researchers with limited computational expertise to conduct realistic and accessible conductivity simulations across various nanostructured films and composite materials.","PeriodicalId":110,"journal":{"name":"Advanced Electronic Materials","volume":"28 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144770035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metal–organic chemical vapor deposition (MOCVD) is the preferred method for depositing highly crystalline, c-axis oriented aluminium nitride (AlN). However, achieving optimal film quality requires vertical surfaces with minimal roughness and uniformity. Traditional etching techniques, such as wet and plasma etching, often result in rough and irregular surfaces, which challenge the crystal quality of the deposited AlN. In this study, cryogenic deep reactive ion etching (cryo-DRIE) is used to fabricate vertical sidewalls with a root mean square roughness of 26 nm and waviness of 131 nm, followed by hydrogen annealing to further enhance surface quality. Hydrogen annealing reduces the roughness to 7 nm, but the waviness varies depending on the pre-annealing surface conditions. When AlN is deposited on these treated surfaces using MOCVD, the films exhibit high crystal quality comparable to those grown on wet-etched surfaces with extremely low roughness. A slight misalignment of the AlN c-axis orientation with the Si (111) plane is observed, with localized surface irregularities impacting grain alignment in specific areas.","PeriodicalId":110,"journal":{"name":"Advanced Electronic Materials","volume":"11 15","pages":""},"PeriodicalIF":5.3,"publicationDate":"2025-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aelm.202500066","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144770036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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, Rozanov et al. posited that reflection minimum depth is insufficient as the quality criteria—a viewpoint that remains under-recognized in scientific discourse so far. This study leverages the quarter-wavelength wavelength relationship in conjunction with transmission line theory to engineer various microwave absorbers composed of ferromagnetic or dielectric materials. The results indicate that each of these absorbers can achieves perfect matching (Zin/Z0 = 1), suggesting that, in practice, they can all achieve the best reflection loss (RL) value of negative infinity, thereby affirming Rozanov ′s perspective. In order to be able to better evaluate MA materials, it is identified that the squared refractive index at perfect matching, denoted as (με)p, serves as a robust quality metric. Experimental results indicate that materials with a higher (με)p value exhibit superior absorption performance. Furthermore, this metric offers valuable insights for the design of low-frequency thin-layer absorbers and for identifying better MA materials. These findings underscore an indissociable link between MA device performance and MA material characteristics.","PeriodicalId":110,"journal":{"name":"Advanced Electronic Materials","volume":"11 14","pages":""},"PeriodicalIF":5.3,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aelm.202500239","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144755961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 paper, a series of artificial cilia is prepared using additive micro-manufacturing technologies for direction-sensitive acoustic sensing, including electrospray and 3D micro-direct ink writing. The response of the artificial cilia at resonance is significantly enhanced, while the resonance frequencies decrease with increasing length, and the response increases due to the amplification. Two resonances are achieved on a cilium by printing two independent electrode-to-electrode interconnect bridges. Two signal channels of the artificial cilia produce an ‘8’-shaped loop by varying acoustic excitation angles, showing that both amplitude ratio and phase difference are direction-dependent. The two voltages of the artificial cilia can be decoupled to produce different frequencies, amplitudes, and phase differences, thus enabling directional detection of multiple sound sources. The direction-sensitive acoustic sensing is achieved by micro-manufacturing artificial cilia.

A total of 54 device architectures are systematically explored by combining six different electron transport layers (ETLs: Ws2, TiO2, C60, PCBM, IGTO, and LBSO) with nine‐hole transport layers (HTLs: CBTS, Cu2O, CuI, CuSCN, P3HT, PEDOT: PSS, PTAA, GaAs, and CdTe), using Ni as the back contact. The ITO/Ws2/Cs2TlAsI6/Cu2O/Ni configuration achieves the highest power conversion efficiency (PCE) of 26.92%. Further optimization examines the influence of absorber thickness, ETL hthickness, and defect densities on performance. Detailed analyses include band alignment (VBO/CBO), interface defects, carrier dynamics, quantum efficiency, capacitance profiles, Mott–Schottky behavior, and impedance spectra. Additionally, the effects of series and shunt resistance, temperature, and back contact selection are investigated. Structural stability of Cs2TlAsI6 is confirmed via tolerance factor analysis, including Goldschmidt's and a newly proposed parameter.
