| Outline of Final Research Achievements |
Enhancement of the magnetostriction and thickening for the magnetostrictive layer and structural optimization as a stacked device have been investigated with a purpose of the boosting generation output of the electro-magnetostrictive multferrioc device as passive-typed electromagnetic field sensor / magnetic field energy-harvester operating.
An Fe-Si-B-P amorphous alloy with a combination of good permeability, relatively high magnetostriction and high grass-forming ability was adopted for magnetostrictive layer. As the results, the critical thickness of the long melt-spun ribbon with single amorphous phase was reached 170 um, and generation output of the device improved with increase the thickness of the ribbon i.e. magnetostrictive layer was confirmed. Additionally leveraging in-plane magnetostriction increase of the annealed ribbon in consequence of partially crystallization only near the surface of the ribbon, enhancement of the output generation of the device has been confirmed.
