Development of a Capacitor Using a Rubber Based Magneto Rheological Elastomer

A capacitor is a passive two-terminal electrical component that stores electrical energy in an electric field. The most famous capacitor current in use the market and industry is a ceramic capacitor. However, the dielectric material used in the industry nowadays involve high cost of material handling due to the fact that the dielectric material is hazardous. Thus, there is a need for exploring the potential of the new material to replace the current dielectric material used in the industry nowadays. In this study, a magnetorheological elastomer with different magnetic particle concentrations from 30 to 70% and different curing processes is proposed as a dielectric material. The MRE capacitor prototype was built by two non-magnetic layers, between there is a layer of the magnetorheological elastomer (MRE) as the dielectric. From the experimental result, the magnetic strength, magnetic particle concentration and curing process of the MRE influence the value of the capacitance. As a conclusion, the MRE material with high iron concentration and anisotropic type can be used as a dielectric to be applied in capacitor development.
