给出了利用铁磁铰链结构实现多步磁性自组装的设计方法。该工艺使用垂直于衬底的外部磁场产生的静磁扭矩来提升铰链结构。铰接结构是由刚性板通过弹性铰链连接到衬底的一侧组成的。如果铰链结构按顺序升高，就有可能组装成日本式的复杂三维结构。在我们之前的研究中，我们发现了一个依赖于其形状的无量纲因子，它决定了铰链微结构对磁场的敏感性。这一因子可以作为顺序批量自组装工艺设计的判据，因为它反映了敏感度的差异。在本研究中，我们使用无量纲化因子来设计多工步顺序装配。利用该方法对四步顺序批量装配进行了演示。这种方法对于由许多复杂的三维结构组成的光学系统将是有用的。(C)2006爱思唯尔B.V.保留所有权利。
We provide the design method of multi-step magnetic self-assembly using ferromagnetic-hinged structures. The process uses the magnetostatic torque generated by an external magnetic field perpendicular to the substrate to lift hinged structures. Hinged structure is composed of a rigid plate connected by elastic hinges to one side of a substrate. If hinged structures are raised in sequential order, it is possible to assemble like Japanese "origami" complex three-dimensional structures. In our previous study, we found that a dimensionless factor that depends on its shape determines the sensitivity of the hinged microstructures to a magnetic field. This factor can be used as a criterion in designing a process for sequential batch self-assembly, because the factor indicates the differences in the sensitivity. In this study, we designed multi-step sequential assembly by using the dimensionless factor. Four-step sequential batch assembly was demonstrated using this method. This method will be useful for optical systems, which consist of many complex three-dimensional structures. (c) 2006 Elsevier B.V. All rights reserved.
