项目摘要

An electro-conjugate fluid(ECF) is a kind of dielectric fluids, which generates a powerful jet flow when subjected to a high voltage (several kV). Although the mechanism of the jet flow, which is called an ECF jet, has not been clarified yet, the fluid is clarified suitable for micro actuation, which means, a much powerful jet flow is observed with a smaller electrode pair. Accordingly, this study aims to develop novel micromotors and micro manipulators using the electro-conjugate fluid, and to realize a tiny helicopter using the components mentioned above for extreme environment like atomic reactors. The followings are the accomplishment of this study.By using the functional fluid, or the ECF, electric energy is easily transformed to mechanical energy. We have applied this interesting fluid to micromotors. Three types of ECF micromotors have been developed. First one is a SE type ECF micromotor, having electrode pairs on the stator. The second one is which we call a DP-RE type ECF mic … More romotor. This motor has electrode pairs on the disk-plate rotors. In addition, a C-RE type ECF micromotor is the third one, having electrode pairs on the surface of cylindrical rotor. The DP-RE type ECF micromotor shows the best performance, and 8-layer DP-RE type ECF micromotor with 5mm in inner diameter is developed.The ECF jet can also be used as a micro pressure source. We have developed an ECF micro manipulator using the pressure source. With increasing the inner pressure of a slightly-curved flexible tube, the displacement of front edge is observed just as Bourdon-tube. We are also developing an ECF micro flexible finger. The flexible tube has 3 parallel chambers along the axis, and inner pressures of each are independently controlled using ECF jet. Up to now, we have proposed the driving principle and investigated the manufacturing procedure using a large model with 4.5mm in diameter.Finally, we theoretically investigated on propeller shape of micro helicopter using the ECF micromotors having high power density.

电共轭流体（ECF）是一种介电流体，当受到高电压（几千伏）时会产生强大的射流。虽然被称为ECF射流的射流的机制尚未澄清，但澄清了适合于微致动的流体，这意味着用较小的电极对观察到更强大的射流。因此，本研究的目的是开发新的微电机和微操作器使用的电共轭流体，并实现一个微小的直升机使用上述组件的极端环境，如原子反应堆。本研究的主要成果如下：利用功能流体，将电能转换为机械能。我们已经将这种有趣的流体应用于微型马达。已经开发了三种类型的ECF微电机。第一种是SE型ECF微电机，在定子上具有电极对。第二个是我们称之为DP-RE型ECF麦克风 ...更多信息 romotor。该电机在盘-板转子上有电极对。第三种是C-RE型电动势微电机，其转子为圆柱形，转子表面有电极对。结果表明，DP-RE型ECF微马达的性能最好，研制出了内径为5 mm的8层结构的DP-RE型ECF微马达。我们已经开发了一个ECF微操作器使用的压力源。随着内压的增加，微弯曲柔性管的前缘也会产生类似于波登管的位移。我们还在开发ECF微型柔性手指。柔性管具有沿轴线沿着的3个腔室，并且每个腔室的内部压力使用ECF射流独立地控制。到目前为止，我们已经提出了驱动原理，并研究了制造过程中使用的大模型，直径为4.5毫米。最后，我们理论上研究了螺旋桨形状的ECF微电机具有高功率密度的微型直升机。少
