| Outline of Final Research Achievements |
We are conducting research on technology to extract practical electric power from minute vibration such as bridge. In this time, the sensitivity was greatly improved by making the magnetostrictive vibration power generation device into a U-shaped frame structure. As a result, we succeeded in extracting a generated voltage of 1 V and electric power of 1 mW or more from a minute vibration of about 30 Hz, about 0.1 G to 0.2 G. As a result, the possibility that the wireless sensor system operates autonomously with minute vibration such as a bridge was demonstrated.
