Problems solved by technology

However, the current research is mainly based on the deformation of the film produced by photobending, which is then used as the power of the actuator. Usually, the lighting device is also an additional platform, so that the integration and miniaturization of photobending actuators or robots cannot be truly realized.
[0005] So far, there have not been any related reports on conductive actuators based on photobendable polymer materials
