反発する磁石の漏れ磁束を利用したウェアラブル触覚提示素子

This study proposes a new haptic transducer capable of producing strong vibrations and constant skin stretch using repulsive permanent magnets and a small coil. The repulsive magnet configuration generates a concentrating leakage magnetic flux on the side surface of the magnets directing perpendicular to the surface. Both the magnets and the coils are attached to the skin to generate constant force as well as vibration. To demonstrate the effectiveness of the proposed method, we fabricated and evaluated a prototype. As a result, it was found that the proposed method is able to present vibrations with larger amplitudes than existing methods. It was also suggested that the proposed method is superior to the existing method in representing the shape and texture of virtual objects.
