Rheology of uncured magnetorheological elastomers

Journal of Physics: Conference Series, 2020
Abstract The aim of this paper is to study rheological properties of uncured magnetorheological elastomers comprising iron particles dispersed in silicon elastomer in relation to particle rearrangement by external magnetic field into oriented structures as this process is strongly affected by viscosity.

Switchable Adhesion of Soft Composites Induced by a Magnetic Field

, 2020
Switchable adhesives have the potential to improve the manufacturing and recycling of parts and to enable new modes of motility for soft robots. Here, we demonstrate magnetically-switchable adhesion of a two-phase composite to non-magnetic objects.

Magnetorheological Effect of Magnetoactive Elastomer with a Permalloy Filler [PDF]

Polymers, 2020
Within the frames of this study, the synthesis of a permalloy to be used as a filler for magnetoactive and magnetorheological elastomers (MAEs and MREs) was carried out. By means of the mechanochemical method, an alloy with the composition 75 wt.% of Fe and 25 wt.% of Ni was obtained.

Galinstan Liquid Metal/Polyurethane Composite as a Multifunctional Stretchable Electrode and Piezoresistive Strain Sensor With Minimal Drift

Advanced Materials Technologies, EarlyView.
Liquid metal additives are processed in elastomer host resulting in highly conductive and stretchable composites. The material functions as a piezoresistive sensor with minimal drift, low stiffness, and enhanced operating range. The film can replace wires to charge a mobile phone at ∼350% strain and monitors bodily motion in real‐time via a portable ...

Hybrid vibration control using magnetorheological dampers and elastomers for civil structural

AIP Advances, 2022
A hybrid vibration control system using magnetorheological (MR) shock absorbers composed of MR dampers and MR elastomers is proposed for structural vibration. A Bouc–Wen model is developed to describe the hysteresis of the MR shock absorbers.
