Outline of Final Research Achievements

The vibration generating electricity tire sensor device was development by combining a high-performance magnetostrictive new alloy (FeCo71at%), magnetic strain vibration generating electricity device (i.e. electric power achieves about 1 mW by impacting alternative loading by small ball in the device.) and a piezoelectric(PZT) fiber stress sensor whose directionality of tire transformation can be separated. Moreover, wireless radio module signals (2.5GHz short distance within 3m) was combined here. These could prove an experimental model-like device of the tire sensor which these three elemental techniques were successfully combined in 2 years project term.
