Glow‐Worm‐Inspired Fluorescent Self‐Healing Actuators for Soft Robot and Reconfigurable Information Encryption

. It exhibits excellent fluorescence performances, such as quantum yields as high as 58.88% and full-widths at half-maximum as narrow as 21 nm. The actuation and fluorescence properties show long-term stability during more than 1100 cycles of near-infrared irradiation and 12 h of ultraviolet exposure. Moreover, the actuator is integrated with color-changing and full-device self-healing functions, enabling a synergetic color/shape change and reconfigurable on-demand fluorescent patterns. Then, a smart gripper and a crawling robot with crawling/rollover motions are demonstrated. Finally, a non-contact dynamic display of reconfigurable encrypted information driven by light is fabricated to mimic light communications of glow-worms. This actuator demonstrates unprecedented multifunctionality, opening new avenues for fluorescent soft robotics.
