The invention provides a pneumatic software actuator, which is a helical structure, and the base body is made of superelastic material. There is an inflatable air cavity inside the base body, and the input air pressure is used as the drive to realize the unfolding movement; the greater the air pressure, the greater the curvature. Small, the negative curvature expansion movement can be realized after the curvature is reduced to 0. A strain-limiting layer is pasted on the outside of the substrate to limit the axial extension movement and enhance the expansion movement. The sealing plug at the end of the substrate is used to block the air cavity and prevent air leakage. . Due to the adoption of the spiral configuration, the present invention can realize unfolding motions in both positive and negative curvature directions with the increase of input air pressure, and can realize a larger range of unfolding motions under a smaller input air pressure. The helical pneumatic soft actuator has good unfolding motion performance and has various potential application fields, such as the medical field, the development of new rehabilitation gloves, and so on.
