2307 機能性流体を用いたマイクロモータに関する研究(S42-2 複雑流体の流動現象(2),S42 複雑流体の流動現象)  [in Japanese] 2307 Study on a Micro-motor Using Functional Fluid  [in Japanese]

A micro-motor using functional fluid with the electrodes on the bottom surface of the mini-cylinder is produced experimentally. A rotor in this micro-motor in the functional fluid rotates by the rotation of the functional fluid, when the unsteady electric fields are added on the electrodes. The micro-motor is 5mm in length and 4mm in inner diameter. To rotate the rotor, three kinds of liquid crystals and a flourinert were injected in the micro-motor. The amplitude of the voltages and the shape of the electrodes are changed to investigate the effect of the unsteady electric fields on the rotational speed of the micro-motor.
