微环境下需要高自由度的操控方法。然而，在通过表面张力进行显微操作的典型方法中，目标的倾斜或旋转是困难的。多针型毛细管被提出用于通过表面张力进行高自由度微操作。多针式毛细管由圆柱形排列的细针、针的直线运动机构和针内部的液体泵机构组成。这些针可以被视为假想的毛细管。如果毛细管充满液体，则毛细管尖端上会形成液滴。因此，可以通过表面张力用毛细管尖端液滴保持目标。此外，当每根针向上或向下移动时，毛细管尖端表面和毛细管尖端液滴发生转变。因此，用毛细管尖端液滴固定的目标可以倾斜和旋转。本文描述了多针型毛细管的设计和制造。实验中评估了线性运动机构的位移和毛细管尖端的变形。然后，对使用多针型毛细管的片式电阻器的操作进行了评估。
High DOF manipulation method is required under microenvironment. In the typical method of micromanipulation by surface tension, however, tilting or rotating of a target is difficult. The multi-needle-type capillary is proposed for high DOF micromanipulation by surface tension. The multi-needle-type capillary is composed of thin needles which are cylindrically arranged, linear-motion mechanisms of the needles and a liquid pump mechanism inside the needles. The needles can be regarded as a hypothetical capillary. In case the capillary is filled with a liquid, then, a droplet is formed on the capillary tip. Therefore, a target can be held with the capillary-tip droplet by surface tension. In addition, the capillary-tip surface and the capillary-tip droplet are transformed when each needle is moved up or down. Therefore, the target, which is held with the capillary-tip droplet, can be tilted and rotated. In this paper, design and fabrication of the multi-needle-type capillary is described. Displacement of linear-motion mechanisms and transformation of capillary tip are evaluated in the experiment. Then, manipulation of chip resistors using the multi-needle-type capillary is evaluated.
