Functionally-graded and composite shape memory actuation

Abstract eng:
If the shape memory materials are applied into actuators, the novel intelligent shape memory actuators can be developed. In the present paper, the development of a functionally—graded shape memory alloy actuator, a functionally—graded shape memory polymer actuator and a shape memory composite actuator is discussed. The simple multi—way actuation can be developed by using the functionally—graded shape memory alloy. The functionally—graded shape memory polymer board, showing the close deformation property of the finger, can be applied to the elements coming into contact with body in the medical actuators. The three—way actuators can be developed by applying the shape memory composite with various kinds of shape—memory alloy and polymer.
