Microdynamics of magnetic particles in complex fluids [PDF]
International audienceThe agregation of magnetic particles in the presence of a magnetic field is the basic phenomenon which underlies all the physcis of magnetorheological (MR) fluids.Although these interactions are well understood when the suspending ...

Thermoresistance and giant magnetoresistance of magnetorheological elastomers [PDF]
A new magnetorheological elastomer composite (MRE) was developed with a resistance which is strongly sensitive both to temperature and pressure. The electrical resistance of this MRE was investigated versus pressure and temperature. The resistance of the composite was recorded versus pressure for seven different values of the temperature. The mechanism

Recent progress on the magnetorheological plastomers
Different from the traditional magnetorheological (MR) fluids and elastomers, the magnetic particles in the plastic MR materials are not ‘deadly’ trapped in the polymer matrix; thus, the MR plastomers exhibit higher MR effects and lower sedimentation ...

A Mini Review of Scientific Designs of Dynamic Responsive Fluids in Battery Technologies
ABSTRACT Dynamic responsive fluids are emerging as transformative elements in the evolution of battery technologies, marking a pivotal shift from static passive designs toward systems that actively sense and adapt to their operating environments. By integrating dynamic responsive fluids, batteries can interact with both internal and external stimuli in

The research introduces a three‐phase electrostatic (ES) clutch with variable mechanical impedance control, specifically designed to enable continuous and precise friction modulation, thereby reducing both force degradation and oscillatory motion. This method effectively resolves conventional ES clutch issues, such as residual charge accumulation and ...
