磁気粘弾性エラストマのセンサ応用に関する検討

抄録

The magnetorheological elastomer (MRE) is known to belong to a class of smart materials whose elastic properties can be varied by an externally applied magnetic field. In addition to the property of the field-dependent stiffness change of the MRE, the electrical resistance of the composite is also changed by the induced strain, thereby providing a new self-sensing feature. In the present study, the MRE is focused on dispersed particles having conductivity and applied to a sensing property, and the electrical resistance of MREs is evaluated. The electrical characteristics test using MREs that are created in a variety of conditions shows that the electrical characteristically resistance changes with the increasing or decreasing load of the compression direction.
