- Vibration Energy Harvesting Using Composite Materials of Amorphous Ribbon and Resin
説明
<p> We propose a novel system for generating vibration power using composite amorphous ribbons as an alternative to cantilevers. While the cantilever is effective for narrowband vibration, the structure of this system is effective for broadband vibration. To prove the effectiveness of this structure, we measured the change in magnetic properties of the composite amorphous ribbon with and without compressive stress applied and and the power generation properties under vibration with a low amplitude and arbitrary frequency. In the measurement of the magnetic properties, the change in magnetic flux density tended to increase as the strain increased. In the measurement of the power generation characteristics, a power generation of 19.2 μW was obtained even at a vibration frequency of 700 Hz and an amplitude of 450 nm, which is not the resonance frequency. The theoretical and experimental values from the two experiments were consistent, confirming that the inverse magnetostriction effect was responsible for the power generation. Therefore, we conclude that the novel structure for generating vibration power using composite amorphous ribbons is effective for low-amplitude broadband vibration.</p>
