Ke Ji Ri Bao· 2025-10-15 00:00
美国科学家研发出一种形似"中国灯笼"的聚合物结构,通过压缩或扭曲等简单操作,就能快速变换出十 几种不同的三维弯曲形态。更引人瞩目的是,这种变形过程可通过磁场远程操控,大大拓展了其应用潜 力。相关研究成果发表于最新一期《自然·材料》杂志。 研究还发现,通过扭曲结构、将灯笼顶部或底部的实心条向内或外折叠,或是组合使用这些操作,还能 创造出更多形态。 通过在结构底部实心条上附着磁性薄膜,研究团队实现了利用磁场远程控制结构的压缩与扭曲。他们还 演示了基于双稳态切换的多种应用场景,例如非侵入式鱼类捕捉器、可调控水流开合的过滤器等。 这类"灯笼"结构未来有望组装成二维或三维系统,在可变形的机械超材料与机器人技术领域大展身手。 (文章来源:科技日报) 这项研究由美国北卡罗来纳州立大学与宾夕法尼亚大学的科研团队合作完成。研究团队先将聚合物薄片 切割成钻石状的平行四边形,再于每条边中央刻出一排平行缝隙,从而在薄片上下两侧形成由实心材料 条连接的均匀色带。接着,将上下实心条的左右两端相连,便构成了一个近似"中国灯笼"的三维结构。 研究团队表示,这一基础结构本身具有"双稳态"特性。若从顶部向下压缩结构,它会逐渐变形,直至达 到某个 ...
