Current Status and Prospects of New Magnetorheological Materials Development

Abstract

　We will explain the development of MR materials that have evolved sequentially from MRfluid, MR-elastomer, to Permanent magnetized elastomers. With the application of paint technology, MR fluid has solved the fatal problem of sedimentation. Then, by solidifying the MR fluid, we created an MR elastomer that shows a unique movement. Finally, a permanent magnetized elastomer was created by magnetizing the MR elastomer using a special magnetic powder. All of these are materials that are expected to be applied to advanced mechanisms such as robots. We will introduce examples of actual applications and introduce the current status and future of MR materials.
