Mechanically responsive materials are promising as next-generation actuators for soft\nrobotics, but have scarce reports on the statistical modeling of the actuation behavior. This research\nreports on the development and modeling of the photomechanical bending behavior of hybrid\nsilicones mixed with azobenzene powder. The photo-responsive hybrid silicone bends away from the\nlight source upon light irradiation when a thin paper is attached on the hybrid silicone. The time\ncourses of bending behaviors were fitted well with exponential models with a time variable, affording\nfitting constants at each experimental condition. These fitted parameters were further modeled using\nthe analysis of variance (ANOVA). Cubic models were proposed for both the photo-bending and\nunbending processes, which were parameterized by the powder ratio and the light intensity. This\nmodeling process allows such photo-responsive materials to be controlled as actuators, and will\npossibly be effective for engineering mechanically responsive materials.
