Abstract Magnetorheological elastomers (MREs) mechanically respond to external magnetic stimuli by changing their mechanical properties and/or shape. Recent studies have shown the great potential of MREs when manufactured with an extremely soft matrix and soft-magnetic particles. Under application field, such present significant stiffening, field is off, they show a softer response, being these alternative states fully reversible. Although particles are suitable for high susceptibility, require actuation remain constant in order achieve magneto-mechanical stiffening. Here, we solution based on hard-magnetic provide stiffening responses that can be sustained along time without need keeping on. To this end, manufacture novel (stiffness 1 kPa) characterise them under shear confined expansion deformation modes, providing comparison framework counterparts. The nature allows easily activating couplings actuation. In regard, approach setting below saturating field. addition, free tests hints microstructural transmission torques from viscoelastic matrix, resulting macroscopic geometrical effects intricate shape-morphing phenomena.
