a The crease pattern and snapshots (the permanent and temporary shapes) of the reconfigurable PCEO strip structure. Hinges are numbered 1 to 7 from top to bottom. The input current and heating time (as guided by simulation) of each hinge and experimental snapshots of different configurations. Scale bars, 20 mm. b Demonstration of the gripper functional configuration by sequence control. Snapshots of the temporary shape and the whole working process (grasp and release a solid adhesive rod) of the robotic gripper. A 3D-printed snap-fit is attached to the end of the PCEO strip structure to achieve self-locking in the working process. Scale bars, 20 mm.
