“…(a) A concentric cylinder-cup rheometer for measuring the shear stress, in which the surfaces of electrodes were both coated with diamond grain layers to avoid sliding. 21 The shear stresses were transferred from the recorded values of a torque sensor (0154 RW sha end version, Dr Staiger Mohilo + CoGmbH, Germany). (b) A high voltage amplier (Trek 10/40A), which was driven by Rigol DG1011 functional generator, supplied high voltage with slew rate $700 V ms À1 .…”

“…The measurement at higher shear rate is baffled by the heating effect especially for the PM-ER fluids possessing high yield stress. 17 Obviously, although T E (γ) − T 0 (γ) or τ E (γ) − τ 0 (γ) almost keeps unchanged in all region of shear rate, the ratio T E (γ)/T 0 (γ) = τ E (γ)/τ 0 (γ) ≈ τ y (E)α −1γ−1 (for α > 0) decreases with shear rate increasing. Where α is the slope of torque increasing with shear rate, which depends on the rheological property of material and the design of clutch.…”

“…This sliding at electrode originates in that the boundary condition at the interface of fluid-electrode is not as the same as inside of ER fluid. 15,17 Therefore, the electrodes for measuring PM-ER fluid must be treated to be rough enough. Even though the measured shear stress still is less than the intrinsic value for the PM-ER fluids with extra large yield stress.…”

In recent years, a new type ER fluids named as polar-molecule-dominated electrorheological (PM-ER) fluids have been developed, of which the yield stress can reach more than 100 kPa and behaves a linear dependence on the electric field. A brief description on the composition and synthesizing method for the materials is given. The main merits of PM-ER fluid are as follows: high yield stress, the shear stress increasing with shear rate up to more than 10 3 s −1 , low current density, rapid electric response and anti-sedimentation. Some perspectives on PM-ER fluid and its applications are presented.

“…Because of these features, electrorheological fluid has attracted significant attention in both scientific and engineering areas during these past years. Several precedent works have been done in the modification of suspension [2][3][4][5], measurement of dynamic responses [6][7][8], inner structure examinations [9][10][11], and theoretical approaches [12][13][14][15]. Application to the machine elements such as clutch, damper [16], and actuator [17,18] is expected.…”

We analyzed a relationship between the viscosity and fine current of the ER suspension aiming for an estimation of the inner structure. This study aimed at an estimation of the inner structure formation via the fine current pass through the suspension. Viscosity and electrical current through electrodes were measured using similar apparatuses, and the relationship between the viscosity and fine current was investigated. The ER suspension was prepared by adding silica particles of 0.5 μm diameter to silicone oil of 0.291 Pa˙s viscosity. The solid volume fraction was 0.20. The voltage was varied from 0 to 1.5 kV/mm. The viscosity of the ER suspension was measured by a falling time in a rectangular tube. As a result, the fine current was found to correlate with the viscosity of the ER suspension. It indicated the possibility that the inner structure of the ER suspension can be estimated using the fine current through the ER suspension. © 2021 Institute of Electrical Engineers of Japan.
