Rheological and Resistance Properties of Magnetorheological Elastomer with Cobalt for Sensor Application
Cobalt particles have been introduced as a filler due to the advantages of embedding their magnetic and electrical properties in magnetorheological elastomer (MRE). In the present research, the rheology and resistance of MRE are experimentally evaluated. Isotropic and anisotropic MRE samples contain...
