| Outline of Final Research Achievements |
In order to develop design criteria to ensure the reliability and long-life capability of biocompatible self- powered electromagnetic devices, we investigated the effects of microstructures, localized magnetic domain switching, magnetic domain wall motion etc. on the power output (energy harvesting) and fracture/fatigue properties of advanced magnetostrictive material systems under magnetic fields theoretically (multi-physics numerical simulation) and experimentally. Based on the study on the power output and fracture/fatigue properties, optimal materials and structures of magnetostrictive systems were discussed.
