Electrorheological Fluids

Science, 1992
Suspensions of polarizable particles in nonpolarizable solvents form fibrillated structures in strong electric fields. The resulting increase in viscosity of these "electrorheological" fluids can couple electrical to hydraulic components in a servomechanism. The physical properties of these fluids are unusual owing to the long-range, anisotropic nature

Rheology of electrorheological fluids

Physical Review Letters, 1992
We present experimental and theoretical results on the shear thinning of electrorheological fluids. Rheological measurements on a model fluid consisting of monodisperse silica spheres immersed in a dielectric liquid show a power-law dependence \ensuremath{\mu}\ensuremath{\propto}\ensuremath{\gamma}${\mathrm{\ifmmode \dot{}\else \.{}\fi{}}}^{\mathrm ...

Electrostatic Layer Jamming Variable Stiffness Enhanced by Giant Electrorheological Fluid

IEEE/ASME transactions on mechatronics
The traditional electrostatic layer jamming (ELJ) utilizes air as the dielectric, which leads to the ELJ system that can withstand less voltage. A novel electrostatic layer jamming based on giant electrorheological fluid (ELJ-GERF) for soft robotics is ...

Electrorheological Fluid Hysteresis

Materials, 2005
Electrorheological (ER) fluids are suspensions of polarizable particles dispersed in insulating liquids. They exhibit a rapid and reversible transition from a liquid-like to a solid-like state upon the application of an electric field. The observed shear stress - shear rate hysteresis makes the precise control of the ER mechanical devices very ...

Rotor vibration control studies with electrorheological fluid lubricant in floating ring bearings

Noise & Vibration Worldwide, 2019
The high-speed rotors are usually supported on fluid-film bearings such as single film hydrodynamic bearings and floating ring type bearings to attain high damping capacity for minimizing the resonant vibration amplitudes. However, the bearing forces are

Negative electrorheological fluids

Journal of Rheology, 2013
Electrorheological (ER) fluids are electroresponsive materials that have been extensively investigated for several decades. Despite negative ER fluids being one of the most promising new class of candidate materials for various potential applications, only positive ER fluids have been widely used thus far.

A giant electrorheological fluid with a long lifetime and good thermal stability based on TiO2 inlaid with nanocarbons

Journal of Materials Chemistry C, 2019
The bottleneck in the application of electrorheological (ER) fluids is the difficulty of simultaneously meeting both the performance and lifetime demands.

Modelling and testing of a hydrodynamic clutch filled with electrorheological fluid in varying degree

Journal of Intelligent Materials Systems and Structures, 2019
The article concerns steady-state characteristics of a hydrodynamic clutch with electrorheological working fluid controlled by changes in strength of electric field and changes in the filling degree. The characteristics were obtained by experimenting, as

An Electrorheological Fluid Actuator for Rehabilitation Robotics

IEEE/ASME transactions on mechatronics, 2018
Transitioning rehabilitation robots from the clinic environment to the home could significantly increase the intensity and accessibility of therapy to stroke survivors. Home-based rehabilitation robots must become smaller and cheaper.

Analysis of giant electrorheological fluids

Journal of Colloid and Interface Science, 2013
The yield stress dependence on electric field strength for giant electrorheological (GER) fluids over the full range of electric fields was examined using Seo's scaling function which incorporated both the polarization and the conductivity models. If a proper scaling was applied to the yield stress data to collapse them onto a single curve, the Seo's ...
