Hydrostatic bearing groove multi-objective optimization of the gear ring housing interface in a straight-line conjugate internal meshing gear pump [PDF]

Scientific Reports
The lubrication performance of a straight-line conjugate internal meshing gear pump is poor under the low-speed, high-pressure operating conditions of the volumetric servo speed control system, and it is difficult to establish a full fluid lubricating ...

An In-Pipe Mobile Robot Using Electro-Conjugate Fluid

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2011
An electro-conjugate fluid (ECF) is a kind of functional fluid, which produces a jet flow (ECF jet) when subjected to high DC voltage. It is known that a strong ECF jet is generated under nonuniform electric field, for example, the field with a pair of ...

Biocompatibility of a droplet-mixing device using an electro-conjugate fluid

Mechanical Engineering Journal, 2016
An electro-conjugate fluid (ECF) is a type of functional fluid that produces a jet flow under a non-uniform electric field. We use an ECF to generate a rotational flow in a tiny cylindrical chamber.

A Bio-Inspired Robot Using Electro-Conjugate Fluid

Journal of Robotics and Mechatronics, 2013
Electro-Conjugate Fluid (ECF) is a kind of functional fluid that produces a jet flow (ECF jet) when subjected to high DC voltage. A strong ECF jet is known to be generated in a nonuniform electric field, for example, a field with a pair of needle and ring electrodes. This study introduces the ECF jet in developing a novel bio-inspired robot.

High-Integration Micromotor Using Electro-Conjugate Fluid (ECF)

Journal of Robotics and Mechatronics, 2005
Electro-conjugate fluid (ECF) is a dielectric fluid, that produces a powerful jet flow (ECF jet) when high DC voltage is applied between electrodes inserted in the fluid, realizing a new simplified, lightweight micromotor. We previously developed a disk-plate type ECF micromotor with inner diameter of 9mm.

Earthworm Type Micromachine Driven by Electro-conjugate Fluid

Journal of the Robotics Society of Japan, 2007
An electro-conjugate fluid (ECF) is a kind of functional fluid which generates a powerful jet flow when subjected to high DC voltage. Using this fluid, this paper proposes a novel earthworm-type peristaltic micromachine. First we describe a motion pattern of earthworm-type peristaltic micromachine, and propose a micro cell using ECF. The cell, composed
