“…This technology provides an approach to enhance the ER effect via applying an additional magnetic field. Iron particles, [117] iron particles coated with titania, [118] glass spheres coated with nickel and titania, [119] and various ferromagnetic particles (such as magnetite, manganese ferrite, barium ferrite, iron, cobalt, nickel, permalloy, iron nitride) coated with metallic oxides (such as SiO 2 , Al 2 O 3 , TiO 2 , BaO) [120] have been reported to show the EMR effect.…”

Materials that switch from liquid‐like to solid‐like upon application of an electric field are termed electrorheological fluids. The general features and preparation of these smart materials are reviewed before recent advances in the improvement and applications (e.g., sensors, damping devices, inks) of these fluids are described. Materials ranging from aluminosilicate (see Figure) and carbonaceous inorganic materials to liquid‐crystal polymers to semiconductive polymers can be used to fabricate electrorheological fluids.

“…The electro-magneto-rheological effect provides inventors with a new strategy to control the rheological properties of active fluids [57,58] by means of a more aggregated and organized structure able to provide a more drastic change of the fluid viscosity [59][60][61][62]. Additionally, the simultaneous application of electric and magnetic fields to a fluid allows controlling the direction and strength of each field independently.…”

“…Additionally, the simultaneous application of electric and magnetic fields to a fluid allows controlling the direction and strength of each field independently. Nevertheless, due to practical reasons, it would be easier to change the direction of the magnetic field rather than that of the electric field, which requires a direct contact between the electrodes and the fluid [61]. Nevertheless, to the best knowledge of the author, practical applications or patents reporting the use of these EMRFs in energy dissipating systems is very scarce [63,64].…”

Abstract:The development of engineered systems for energy dissipation (or absorption) during impacts or vibrations is an increasing need in our society, mainly for human protection applications, but also for ensuring the right performance of different sort of devices, facilities or installations. In the last decade, new energy dissipating composites based on the use of certain complex fluids have flourished, due to their non-linear relationship between stress and strain rate depending on the flow/field configuration. This manuscript intends to review the different approaches reported in the literature, analyses the fundamental physics behind them and assess their pros and cons from the perspective of their practical applications.

“…Electroactive polymers offer novel and promising characteristics such as light weight, high flexibility, and high energy density. The examples of electroactive materials are dielectric elastomers [2], electrostrictive papers [3], conductive polymers [4], electrorheological fluids [5], ionic polymer gels [6], and ionic polymer metal composites [7].…”
