The cantilever, 10mm in length, consists of a 3micron-thick polyimide substrate, and magnetostrictive thin films on both sides. Positive magnetostriction TbFe amorphous film is sputtered on one side and negative magnetostriction SmFe amorphous film is on opposite side.
The cantilever is actuated by external magnetic field. In this video, magnetic field is applied to the width direction. The amplitude of the oscillation showed a peak at its resonance frequency.
