Miniaturized and high-powered micro pump using electro-conjugate fluid

Prototype models of high-powered micro pump module for micro fluid power actuation systems are fabricated and experimentally investigated. The functional fluid; ECF (Electro- Conjugate Fluid) is used to be pumping function for the micro pump module. The fluid power source using the ECF can be embedded in the main body of the micro fluid power actuation can be effective as driving source of the actuator. Some kind of novel electrodes in the pump module is fabricated by a micro electric discharge machining. The shape and arrangement of the electrodes on the delivery pressure of the pump due to the ECF jet are experimentally investigated. The pressure due to the ECF jet strongly depends on the number and shape of the pair of electrodes. A new shape of electrodes is proposed to miniaturize the high-powered micro ECF pump module.
