Electro Hydro Dynamics (EHD) fluid is a kind of intelligent fluid. The fluid has the property that a fluid jet flow is generated between two electrodes when a high voltage is applied. DBDN (Di n-butyl dodecandioate) is a kind of EHD fluid and a dielectric organic liquid. The main purpose of this study is to develop a lightweight and compact fluid actuator which makes use of such properties of EHD fluid. We think that it is useful to apply EHD actuators to a micro actuating System as a lightweight actuator. In order to develop such an actuator, we first investigated the characteristics, the relation between the generated pressure and applied voltage to DBDN fluid. In this study, we tested two kinds of pumping module ; a direct type and a suction type. The direct type module consists of two doughnut shaped electrodes. The suction type module consists of a flat plate electrode and a cylindrical electrode. We investigated the relation between applied voltage and generated differential pressure using these modules. Further, we investigated the influence of geometric parameters on the characteristics of the module.
