Electro-Conjugate Fluid (ECF) is a kind of dielectric fluids and a kind of functional fluids, which produces jet-flow (ECF-jet) by applying high voltage between electrodes. In addition, a strong ECF-jet is generated under ununiform electric field. Therefore, in this study, a pair of needle-type and ring-type electrodes (needle-ring pair) is used for generating ECF-jet. It is ascertained that the pressure due to ECF-jet from the needle-ring pair is increased by miniaturizing dimensions of the electrodes. The characteristics are suitable for micro manipulator. Therefore, the purpose of this study is the realization of novel micro manipulators using ECF-jet. In this paper, first, characteristics of ECF-jet from the needle-ring pair are experimentally investigated. Second, a novel micro manipulator, ECF micro finger is proposed. Finally, a large model of the ECF micro finger is fabricated, and static characteristics of the large model is experimentally investigated. Future works are fabrication and investigation of a microhand constructed with more than three ECF micro fingers.
