A composite structure for smart morphing skin was designed by using two-way shape memory alloy (SMA) wires as the active component and utilizing balsa wood and flexible polymer. The mechanical principle of deformation was presented. The relationship between the deformation effect and deformation of shape memory alloy was analyzed. The structure design for smart morphing skin was introduced. A method of injection molding to finalized fully flexible composite structure to form composite structure was used. The volt-ampere and load-actuation deformation behavior of the composite structure are characterized. The results indicate that the composite structure can realize continuous deformation. The actuator can reach its maximum deformation in 0.15s at 25V.
