A composite actuator by combining a shape memory alloy and a ferromagnetic material was designed and fabricated because it can be driven with high speed as well as considerably large deflection by a wireless magnetic field. As for the elemental material, a shape memory alloy CuAIMn and a ferromagnetic material Fe were selected and laminated. The following characteristic evaluations were performed. 1) difference of the material properties and actuator performance between sandwiches structure(SS) and bimorph structure(BS). 2) strength of the composite material when changing the thickness and elemental ratio of structured material 3) response time in magnetic field. Consequently, these results can the possibility of a new type of composite actuator.
