仿生设计

In this paper, we newly propose a microarm which has a bionic joint for medical application, especially for minimally invasive surgery. The novel design of bionic joint has a characteristic of the stiffness anisotropy of insect legs, and comprised of several materials which have different stiffness characteristics. The advantages of proposed joint are as follows: (1) small, (2) flexible, (3) simple mechanism fabricated by stacking microassembly process, and (4) biocompatible.

Diphylleia Grayi诱导的水致变色纳米/微结构薄膜因其简单、低成本、节能的策略而受到广泛关注，具有广阔的应用前景。通过选择性去除聚二甲基硅氧烷( PDMS )薄膜表面嵌入的纳米/微球聚苯乙烯阵列，提出了一种新型的具有不同纳米/微米空气孔反蛋白阵列的可调水玻璃膜。利用漂白与散射态的显著对比度，我们对Mie散射模式的开关性质进行了优化。因此，我们得到了一个单反蛋白石层嵌入PDMS胶膜，六边形密排1μm的空气孔阵列作为最佳的散射膜。最佳分散膜的干态和湿态扩散透过率和光学雾度值的差异分别达到44.93 % ( ΔTD . T = 59.11 - 14.18 % )和54.88 % ( ΔH = 69.42 - 14.54 % )。此外，我们还利用优化的反蛋白层嵌入PDMS薄膜，制作了一种完全模仿Diphylleia Grayi结构的伪装应用和一种智能水致变色窗口器件。动态水调制反蛋白图案PDMS胶膜的分散不透明和不分散透明状态，可为智能窗、伪装和雨天晴雨伞的水致变色技术领域提供先进的平台结构。
