Abstract

Permanent magnet elastomers are three-dimensional deformable permanent magnets, which are novel functional materials in which the magnetic field around the elastomer changes during deformation. The detection of the magnetic field variation enables the realization of tactile sensors. Considering the application of tactile sensors, it is important to understand their viscoelastic properties. In the present study, the rheological properties of permanent magnet elastomers in stretch deformation were investigated. The results show that the viscoelasticity changes due to magnetization. Additionally, this variation due to magnetization was discussed by fitting it into a four-element mechanical model.
