Magnetic-field Driven Micromachine Applying Multi-functional Fe-Pd

摘要：

To apply ferromagnetic shape memory Fe-Pd alloy for a micromachine,we investigated the behavior of the shape memory effect for rapidly solidified Fe-29.6at％ Pd alloy ribbons.These ribbons exhib-ited a reversible two-way shape memory effect in the temperature range of 273 to 403K.On the basis of the development of an actuator of the Fe-29.6at％ Pd ribbon,a small simple-structured micromachine system was fabricated.A wireless micromachine is controlled remotely by an alternating magnetic field:it is able to swim in a fine liquid pipe and move forward or backward by changing the frequency of the applied alternating mag-netic field.Moreover,this micromachine grips a small ball(the diameter～0.5mm).The grip released a small ball at a water temperature of 340-350K by supplying microwave energy from the outside of the water pipe.
