电共轭流体（ECF）是一种功能流体，当受到高直流电压时会产生射流（ECF喷射）。已确定在不均匀电场下，例如在一对针电极和环电极(针环电极对)周围产生强ECF射流。本研究提出并开发了一种使用 ECF 喷射进行双自由度运动的新型微手指。首先，我们提出了一种由ECF喷射驱动的新型微指（ECF微指）的概念。 ECF 微指由沿其轴具有三个腔室的指管和具有三个针电极和具有三个孔的板电极的 ECF 喷射发生器组成。当 ECF 射流发生器产生的 ECF 射流施加到指管的腔室时，加压腔室膨胀而其他腔室收缩，导致指管弯曲。接下来，制造了所提出的 ECF 微指的大型模型，其指管直径为 4.5 mm，以证实我们的概念。最后，我们通过实验研究了大模型的静态特性。 (C) 2006 Elsevier B.V. 保留所有权利。
Electro-conjugate fluid (ECF) is a kind of functional fluid, which produces jet flow (ECF jet) when subjected to high DC voltage. It is ascertained that a strong ECF jet is generated under nonuniform electric field, for example, around a pair of a needle-electrode and a ring-electrode (a needle-ring electrode pair). This study proposes and develops a novel micro finger with two-DOF motion using ECF jet. First, we propose a concept of novel micro finger driven by ECF jet (ECF micro finger). The ECF micro finger consists of a finger tube with three chambers along its axis and an ECF jet generator with three needle-electrodes and a plate-electrode with three holes. When the ECF jet generated at the ECF jet generator is applied to the chambers of the finger tube, the pressurized chambers expand and the other chambers shrink resulting in the finger tube bending. Next, a large model of the proposed ECF micro finger, with finger tube diameter of 4.5 mm, is fabricated in order to confirm our concept. Finally, we investigate the static characteristics of the large model by experiments. (C) 2006 Elsevier B.V. All rights reserved.
