In order to improve the security and reduce the leakage of information, and further broaden the application fields of information privacy, this work reported a novel information cheating technology based on a light-driven bimorph soft actuator. Firstly, the as-prepared gold nanorods with different aspect ratios were uniformly dispersed into the polypropylene/polyimide composite membrane by means of mask depositing and coating, and then a photothermal biomorph soft actuator was fabricated, after that, the obtained bimorph soft actuator was selectively cut. Herein, we defined the state presented by the bimorph soft actuator without external light stimulation as the first information; only when triggered by the corresponding laser, this soft actuator could display second type of information, which we defined as the second false information; since the highest photothermal conversion of gold nanorods only occurred under the laser with corresponding wavelength, the temperature of different areas observed by the infrared camera showed the new information, which played an important role in information cheating. The experimental results showed that the soft actuator kept in flat state without illumination, and the cutting area of bimorph soft actuators reached a bending angle of at least 50° under the stimulation of corresponding laser, thus the displayed information can be clearly observed by the naked eye; while the difference of photothermal area and non-photothermal area can only be observed in the infrared camera, where the gap of temperature was at least 10 ℃, and the displayed true information could be clearly seen. The combination of the soft actuators and the information cheating is novel and effective, which provides a new strategy toward development and future of information security issues.
