Abstract
A magnetorheological (MR) fluid-based device including an MR piston assembly. The MR piston assembly includes a ferromagnetic MR piston core and an electric coil. The MR piston core has a central longitudinal axis and has an outer circumferential surface substantially coaxially aligned with the central longitudinal axis. The electric coil is positioned in the MR piston core and is substantially coaxially aligned with the central longitudinal axis. A portion, or at least a portion, of the electric coil is buried in the MR piston core under the outer circumferential surface.
