Driving Flip Origami Motions with Thermal-Responsive Shape Memory Alloy

This paper proposes a motion generation approach to flipping origami models. According to the geometrical principle of an infinite flip origami and using the shape memory properties of nickel-titanium alloy with temperature change, the memory alloy spring is selected as the driving units of origami motions. With conductivity, aluminum foil paper is selected as the wire connecting the memory alloy spring. By designing different circuit connection manners, the memory alloy spring will change the temperature deformation and then drive the movement of the origami. The paper provides a detailed description of how to use the geometric principle to design the origami shape, and analyze the movement principle of the model. We use aluminum foil paper and memory alloy spring with serial and parallel circuit design to study the motion form of the combination of origami and memory alloy spring.
