已经开发出由施加的磁场致动的人工纤毛。在我们以前的报告中，我们展示了几毫米尺度的致动纤毛，这是通过切割磁性弹性体片制造的。制造的人造纤毛的工作类似于天然纤毛，但是，它们具有比天然纤毛大得多的结构，并且显示出在微全分析系统（mu TAS）领域中用于泵送系统的困难。因此，我们的目标是进一步小型化。在这项研究中，我们介绍了一种新的工艺制造更小的支柱结构与磁取向的每个支柱紫外线（UV）激光加工。我们还通过模具和铸造工艺的交替激光加工为支柱组提供不同的方向。(C)2017日本应用物理学会
Artificial cilia actuated by an applied magnetic field have been developed. In our previous report, we demonstrated actuated cilia of a few millimeters scale, which were fabricated by cutting a magnetic elastomer sheet. The fabricated artificial cilia worked similarly to natural cilia; however, they had a much larger structure than natural ones, and showed difficulty for use in pumping systems in micro-total analysis systems (mu TAS) fields. Thus, our goal is further miniaturization. In this study, we introduce a new process of fabricating smaller pillar structures with a magnetic orientation in each pillar by ultraviolet (UV) laser machining. We also give different orientations to groups of pillars by the alternate laser machining of the mold and casting processes. (C) 2017 The Japan Society of Applied Physics
