A reconfigurable micro-gripper. A gripper in its initial, open stage (a) closes upon red-light illumination (b) and returns back to the original state when turning off the light. After UV exposure, the gripper closes upon red-light illumination (c) and maintains the closed state even after ceasing the irradiation (d). e Series of optical images of the gripper operated in a grip-and-release mode, and f the same device reprogrammed to operate in a grip-and-hold mode. Object being lifted up in (e, f) is 12 mg in weight. All scale bars: 5 mm
