Numerical modeling of electro-conjugate fluid flows
Sensors and Actuators A: Physical, 2010An electro-conjugate fluid (ECF) is a kind of low conductivity dielectric fluid, which produces a strong flow when subjected to high DC voltage. ECFs are potentially useful in a variety of applications, including microactuators, microgyroscopes, and CPU liquid cooling systems. However, the biggest hindrance to the commercial development of applications

Dominant factors inducing electro-conjugate fluid flow
Sensors and Actuators A: Physical, 2011An electro-conjugate fluid (ECF) is a kind of dielectric fluid which produces a powerful flow (ECF jet) when subjected to high DC voltage. The ECF jet is a promising micro fluid power source for actuators and sensors including micro motors, liquid rate gyroscope, etc., however, these applications are developed upon trials and errors because the theory ...

Robot Finger Using Electro-Conjugate Fluid
Advanced Robotics, 2010Electro-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 needle and ring electrode (a needle-ring electrode pair). This study introduces the ECF jet to develop a

An inchworm robot using electro-conjugate fluid
2012 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2012An electro-conjugate fluid (ECF) is a kind of functional fluid, which produces a flow (ECF flow) when subjected to a high DC voltage. This study develops a novel inchworm robot having flexible body and using two suckers both of which are driven by the ECF flow. The robot imitates the movement pattern of inchworm and is introduced the ECF to realize the

Robotic earthworm using electro-conjugate fluid
International Journal of Applied Electromagnetics and Mechanics, 2010This study develops a novel robotic earthworm using electro-conjugate fluid (ECF), which generates a jet flow with high DC voltage. The robot, inside of which is filled up with ECF, has two ECF jet generators sandwiched with three flexible silicone rubber tubes (all components are located in series).

Governing equations for electro-conjugate fluid flow
SPIE Proceedings, 2013An electro-conjugation fluid (ECF) is a kind of dielectric liquid, which generates a powerful flow when high DC voltage is applied with tiny electrodes. This study deals with the derivation of the governing equations for electro-conjugate fluid flow based on the Korteweg-Helmholtz (KH) equation which represents the force in dielectric liquid subjected ...

DP-RE type Micromotors using Electro-conjugate Fluid
Proceedings 2007 IEEE International Conference on Robotics and Automation, 2007This paper presents a new type of micromotor using electro-conjugate fluid (ECF). An electro-conjugate fluid is a kind of dielectric fluid, which works as a smart fluid. The fluid generates a powerful jet flow, which we call an ECF jet, when subjected to high DC voltage with highly non-uniform electric field, which means, it works as a fluid power ...

A Micro Artificial Muscle Actuator using Electro-conjugate Fluid
Proceedings of the 2005 IEEE International Conference on Robotics and Automation, 2006Soft robots inspired from natural systems are one of the main research topics in the robotic field since the last decade. Accordingly, artificial muscles were widely investigated due to their potentials in soft machines or soft robots. Many types of artificial muscles have been developed, including pneumatic actuators, ion-exchange polymer composite ...
