A Smart Fluid-Hydraulic System Based on MRF Valve Control and Its Application in Flexible Grasping. [PDF]

open access: yesAdv Sci (Weinh)
This study introduces a smart fluid hydraulic system using MRF valve control for flexible gripping. An MRF‐MSV with an integrated excitation coil and micro‐textured damping channels is designed and validated; micro‐texturing increases hydraulic resistance. Coupled with a soft actuator, the MRF‐MSV enables dynamic bending and grasping.

Electrorheological Fluid Dynamics [PDF]

open access: yesPhysical Review Letters, 2008
We use the Onsager principle to derive a two-phase continuum formulation for the hydrodynamics of the electrorheological (ER) fluid, consisting of dielectric microspheres dispersed in an insulating liquid. Predictions of the theory are in excellent agreement with the experiments.

Engineering Layered Magnetic Hydrogels for Cell Placement via Shear and Magnetic Field-Induced Assembly. [PDF]

open access: yesAdv Mater
Magnetic particles are organized into layered architectures by combining shear flow and magnetic fields, with the resulting structures governed by appropriate Mason numbers. The programmed assemblies provide spatial guidance for cell placement, linking field‐controlled self‐assembly, flow‐induced structuring and biological organization.

Structure of electrorheological fluids [PDF]

open access: yesThe Journal of Chemical Physics, 2000
Specially synthesized silica colloidal spheres with fluorescent cores were used as model electrorheological fluids to experimentally explore structure formation and evolution under conditions of no shear. Using confocal scanning laser microscopy we measured the location of each colloid in three dimensions.

Sedimentation upon different carrier liquid in giant electrorheological fluid and its application

open access: yesFrontiers in Materials, 2014
When giant electrorheological (GER) fluid is settled after some time, particles can precipitate out of the oil in a multistep process that involves the formation of larger particles, the aggregation of colloids, and eventual sedimentation.
