On the sensing of magnetorheological elastomers

In this study, combined effects of magnetic fields and applied mechanical compression load on the electrical resistivity behavior of magnetorheological elastomers (MREs) is studied. MREs with different particle volume percentages are prepared and tested under constant temperature. The theoretical study was performed using a finite element analysis to understand MRE’s deformation subjected to a magnetic field. The coupled magnetic and elastic fields’ equations are employed to determine the magnetic attraction force between the particles. Magnetostriction and magnetoresistance are evaluated to determine the piezoresistivity effect of MREs under the combined loading condition.
