Abstract: In order to solve the dynamic analysis and interactive imaging control problems in the deformation process of bionic soft lenses, dielectric elastomer (DE) actuators are separated from the convex lenses, and data-driven eye-controlled motion technology is investigated. According to the DE properties which are consistency with the deformation characteristics of hydrogel electrodes, the motion and deformation effects of eye-controlled lenses under film prestretching, lens size and driving voltage, are studied. The results show that when the driving voltage increases to 7.8 kV, the focal length of the lens, whose prestreching λ is 4, and the diameter d is1 cm, varies in the range of 49.7 mm and 112.5 mm. And the maximum focal‒length change could reach to 58.9%. In the process of eye controlling design and experimental verification, the high DC voltage supply was programmed and the eye movement signals for controlling the lens were analyzed by MATLAB software. The eye-controlled interactive real-time motion and tunable imaging of the lens were realized. The response efficiency of soft lenses could reach over 93%. The adaptive lens system developed in this research has the potential to be applied to medical rehabilitation, exploration, augmented reality (AR) and virtual reality (VR) in the future.
