Paper Abstract

Two kinds of high power actuator film materials prepared by PVD process were developed. One is the The Fe-Pd alloy film, which shows large magnetostriction and high magnetostrictive susceptibility at low magnetic field from earth magnetic field to 1 kOe. Another is the hydrogen storage La-Ni alloy film on a polyimide substrate, which was prepared using a flash evaporation method. The hydrogen storage alloy film showed the reversible shape change, which operated by hydrogen absorption and desorptions. This bi-material actuator was driven by the large volume expansion of hydrogen storage La-Ni alloy film. In this study, the strain changes were measured under different loading stresses. The powers of these two actuator materials were larger than that of Ni-Ti alloy commercially used.
