| Outline of Final Research Achievements |
"Quincke rotation" is the rotation of non-conducting objects immersed in dielectric liquid and subjected to a strong uniform DC electric field. The rotation is spontaneous when the field exceeds a threshold value. In this research, for the purpose of developing a micro motor utilizing the Quincke rotation, electro-active polymer composites and an epoxy-based polymer SU-8 have been developed as materials for a micro motor rotor, and the motor characteristics are investigated as a function of applied uniform DC electric field intensity, the diameter and thickness of the rotors with shapes such as disk, hollow cylinder and gear. The rotational speed of the micron-sized rotors can be conveniently tuned in wide range (between 200 - 3000 rpm) by the electric field intensity, opening new perspectives for their use in several MEMS applications. Finally, a miniaturized cubic motor of 3mm square and 7mm height with the polymer composite rotor has been fabricated.
