However current technologies still unsatisfy practical uses due to the limitations of sensing and decoding capabilities. Here, A continuous sign language recognition system is proposed with multimodal hand/finger movement sensing and fuzzy encoding, trained with small word-level samples from one user, but applicable to sentence-level language recognition for new untrained users, achieving data-efficient universal recognition. A stretchable fabric strain sensor is developed by printing conductive poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) ink on a pre-stretched fabric wrapping rubber band, allowing the strain sensor with superior performances of wide sensing range, high sensitivity, good linearity, fast dynamic response, low hysteresis, and good long-term reliability. A flexible e-skin with a homemade micro-flow sensor array is further developed to accurately capture three-dimensional hand movements. Benefitting from fabric strain sensors for finger movement sensing, micro-flow sensor array for 3D hand movement sensing, and human-inspired fuzzy encoding for semantic comprehension, sign language is captured accurately without the interferences from individual action differences. Experiment results show that the semantic comprehension accuracy reaches 99.7% and 95%, respectively, in recognizing 100 isolated words and 50 sentences for a trained user, and achieves 80% in recognizing 50 sentences for new untrained users.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"7 4","pages":""},"PeriodicalIF":22.7,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.12642","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143827050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A deeper understanding of the impact of ambient conditions (e.g., moisture, oxygen, and illumination) on the possible reactions of FA-based perovskite films and their processing sensitivities has become critical for further advances toward commercialization. Herein, we investigate reactions that take place on the surface of the FA<sub>0.7</sub>Cs<sub>0.3</sub>, mixed Br/I wide bandgap perovskite thin films in the presence of humid air and ambient illumination. The treatment forms a surface layer containing O, OH, and N-based anions. We propose the latter originates from formamidine trapped at the perovskite/oxide interface reacting further to cyanide and/or formamidinate—an understudied class of pseudohalides that bind to Pb. Optimized treatment conditions improve photoluminescence quantum yield owing to both reduced surface recombination velocity and increased bulk carrier lifetime. The corresponding perovskite solar cells also exhibit improved performance. Identifying these reactions opens possibilities for better utilizing cyanide and amidinate ligands, species that may be expected during vapor processing of FA-based perovskites. Our work also provides new insights into the self-healing or self-passivating of MA-free perovskite compositions where FA and iodide damage could be partially offset by advantageous reaction byproducts.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"7 2","pages":""},"PeriodicalIF":22.7,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.12643","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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, there is lacking in profound study on the effect of electronic structure regulation on sensing performance. Herein, we propose an innovative strategy of Jahn–Teller distortion-induced electronic configuration regulation of Co<sub>3</sub>O<sub>4</sub> to improve acetone sensing performance. After the introduction of Mn<sup>3+</sup> into Co<sub>3</sub>O<sub>4</sub> (Mn-Co<sub>3</sub>O<sub>4</sub>), the Jahn–Teller distortion of high-spin Mn<sup>3+</sup> (t<sub>2g</sub><sup>3</sup>e<sub>g</sub><sup>1</sup>) conversed to low-spin Mn<sup>4+</sup> (t<sub>2g</sub><sup>3</sup>e<sub>g</sub><sup>0</sup>), resulting in conversion of Co<sup>3+</sup> (t<sub>2g</sub><sup>6</sup>e<sub>g</sub><sup>0</sup>) into Co<sup>2+</sup> (t<sub>2g</sub><sup>6</sup>e<sub>g</sub><sup>1</sup>). As expected, Mn-Co<sub>3</sub>O<sub>4</sub> exhibits a high response value of 46.7 toward 100 ppm acetone, low limit of detection of 0.75 ppb, high selectivity, and high stability, which are overwhelmingly superior to previous Co<sub>3</sub>O<sub>4</sub>-based acetone sensors. The dynamics and thermodynamics analysis demonstrate that the Mn doping improves sensing reaction rate, reduces reaction barrier, and promotes the charge transfer. The theoretical calculations further prove the charge transfer from Mn to Co derived from Jahn–Teller distortion and support promoting the adsorption of acetone on Co<sub>3</sub>O<sub>4</sub> by Mn dopant. Moreover, we demonstrated the substantial potential application of Mn-Co<sub>3</sub>O<sub>4</sub> sensor as a monitoring gas sensor in pest resistance of Arabidopsis.

By varying the pressure, the effective absorption bandwidth (EAB) of Fe@CNFs@Co/C elastic aerogels shows continuous changes from low frequency to high frequency. The EAB of Fe@CNFs@Co/C elastic aerogels is 14.4 GHz (3.36–17.76 GHz), which covers 90% of the range of S/C/X/Ku bands.

However, due to issues with sealing, anchoring, and difficult deployment over large areas, TENG still cannot achieve large-scale wave energy capture. Here, a submerged and completely open solid–liquid TENG (SOSL-TENG) is developed for ocean wave energy harvesting. The SOSL-TENG is adapted to various water environments. Due to its simple structure, it is easy to deploy into various marine engineering facilities in service. Importantly, this not only solves the problem of difficult construction of TENG networks at present, but also effectively utilizes high-quality wave energy resources. The working mechanism and output performance of the SOSL-TENG are systematically investigated. With optimal triggering conditions, the transferred charge (<i>Q</i><sub>tr</sub>) and short-circuit current (<i>I</i><sub>sc</sub>) of SOSL-TENG are 2.58 μC and 85.9 μA, respectively. The wave tank experiment is taken for fully demonstrating the superiority of the SOSL-TENG network in large-scale collection and conversion of wave energy. Due to the excellent output performance, TENG can harvest wave energy to provide power for various commercial electronic devices such as LED beads, hygrothermograph, and warning lights. Importantly, the SOSL-TENG networks realizes self-powered for electrochemical systems, which provides a direction for energy cleanliness in industrial systems. This work provides a prospective strategy for large-scale deployment of TENG applications, especially for harvesting wave energy in spray splash zones or at the surface of the water.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"7 3","pages":""},"PeriodicalIF":22.7,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.12621","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
