However, it remains a great challenge to simultaneously achieve high actuation efficiency, programmable deformations, real-time feedback, and robustness. Herein, a textile engineering approach is harnessed to integrate multifunctionality into woven actuators by tailoring yarn groupings using all-in-one industrial weaving technologies. The unique nearly zero Poisson’s ratio inflatable deformation of the actuators contributes to a large bending strain (2,250° m−1), a high output force (30 N MPa−1), and robust mechanical performance. Bilateral bending actuators with negative, zero, and positive curvatures are realized by hierarchical shape transformations of the woven layers. The embedded sensing yarns provide facile and effective methods to proprioceptively sense actuation deformation without compromising actuation performance. Moreover, this manufacturing method is cost efficient and highly scalable, which expands practical applications of soft actuators in healthcare and offers a new perspective on the structure design of customized soft actuators.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"98 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141882800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the utilization of their uncommon physical and mechanical behaviors remains underexplored because existing fabrication processes limit the decoupling of structural frameworks from the responsive mechanisms. Here, we propose a multi-step fluidic control programming strategy by fabricating three-dimensional (3D) magnetic soft materials (MSMs) with reconfigurable mechanical metamaterial behaviors, enabling magnetic-field-driven alteration between three different geometry modes in a single structure. The MSM lattices exhibit fast 3D transitions between positive (νmax = 3.41) and negative (νmax = −2.64) Poisson’s ratios. We then create MSMs with reconfigurable orthotropic behaviors, which demonstrate the positive and negative Poisson’s effect in perpendicular planes. In further demonstrations, the fast and wireless response is validated by manipulating falling loads and switching the states of electrical circuits. This research provides a controllable workflow for future magnetic soft metamaterials.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"31 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141865486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the overall performance of such oxide materials is still limited by low tap density and finite conductivity. Here, we present a type of densely packed titanium dioxide (TiO2) composite that comprises three-dimensional aligned mesoporous TiO2 microspheres and coated ultrathin mesoporous carbon shells. The fabricated mesoporous meso-TiO2@meso-C complex possesses a highly accessible surface area (134 m2 g−1), dual mesopore channels (11.8 and 21.6 nm), and a much higher tap density (1.52 g cm−3). As expected, this designed mesoporous composite achieves superior electrochemical performance, including both a maximized specific capacity of 255 mAh g−1 and a volumetric capacity of 390 mAh cm−3 at 0.025 A g−1. Our mesoscopic composite electrode that enables fast redox reaction reveals the importance of incorporating conductive and dense mesostructures as an alternative pathway for high-volumetric pseudocapacitive materials.","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"79 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141778872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
