Renormalization of the critical exponent for the shear modulus of magnetoactive elastomers [PDF]

Scientific Reports, 2018
AbstractIt is shown that the critical exponent for the effective shear modulus of a composite medium where a compliant polymer matrix is filled with ferromagnetic particles may significantly depend on the external magnetic field. The physical consequence of this dependence is the critical behavior of the relative magnetorheological effect.

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies [PDF]

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Multifunctional and Reprogrammable Magnetoactive Graphene Oxide Origami [PDF]

Advanced Science, Volume 13, Issue 1, 5 January 2026.
A magnetic graphene oxide film is developed that enables rapid, precise, and programmable shape morphing under magnetic actuation. The MGO sensoriactuators feature humidity‐tunable performance and integrated sensing–actuation capability. Customized origami structures can be easily created by simple cutting and folding, while reusable magnetic stickers ...

Effect of Material Composition on Tunable Surface Roughness of Magnetoactive Elastomers [PDF]

Polymers, 2019
We investigated magnetic-field-induced modifications of the surface roughness of magnetoactive elastomers (MAEs) with four material compositions incorporating two concentrations of ferromagnetic microparticles (70 wt% and 80 wt%) and exhibiting two shear storage moduli of the resulting composite material (about 10 kPa and 30 kPa).

Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors

Advanced Intelligent Systems
We present an untethered, neutrally buoyant, metachronal swimmer inspired by ctenophores (comb jellies). Meridional rows of individual propulsors, made from magnetoactive elastomers, are actuated from within a rigid body using a spiral magnetic drive ...

Magneto‐X Effects in Magnetic Soft Materials and Their Applications [PDF]

Advanced Science, Volume 13, Issue 18, 27 March 2026.
This review systematically explores magnetic soft materials (MSMs), a novel class of composites that transform under magnetic fields. It catalogs fundamental “Magneto‐X” effects, classifies materials by their matrix and magnetic fillers, and highlights transformative applications in soft robotics, biomedical devices, flexible electronics, etc. Finally,

Neutron scattering reveals magnetic field-induced microparticle restructuring in densely packed magnetoactive elastomers

Materials & Design
Magnetoactive elastomers (MAEs) exhibit large magnetic-field-dependent changes in mechanical and surface properties, yet the underlying particle-scale mechanisms remain insufficiently understood. In this work, ultra-small-angle neutron scattering (USANS)

Large-Scale Shape Transformations of a Sphere Made of a Magnetoactive Elastomer [PDF]

Polymers, 2020
Magnetostriction effect, i.e., deformation under the action of a uniform applied field, is analyzed to detail for a spherical sample of a magnetoactive elastomer (MAE). A close analogy with the field-induced elongation of spherical ferrofluid droplets implies that similar characteristic effects viz.
