Abstract

The invention relates to the technical field of depth-of-field 3D imaging, zoom imaging, robot vision systems and the like, in particular to a focal length adjustable lens based on a dielectric elastomer driver. The focal length adjustable lens comprises a lens body, and the dielectric elastomer driver comprises a dielectric elastomer annular film, a flexible electrode and an annular frame. The lens body comprises a lower-layer transparent silicone rubber film body which is arranged at the central position of the dielectric elastomer annular film and is integrally cured and formed with the dielectric elastomer annular film, a hemispherical cavity with an upward opening is formed in the lower-layer transparent silicone rubber film body through a vacuum suction device, the hemispherical cavity is filled with a transparent liquid medium, and an upper-layer transparent silicon rubber film body for covering and sealing the transparent liquid medium is arranged above the transparent liquid medium. The invention further discloses a method for preparing the focal length adjustable lens. According to the invention, good zoom imaging effect, high electromechanical performance, fast response speed, long service life, high automation degree, high preparation efficiency, simple process and low cost can be realized.

Description

technical field

[0001] The invention relates to technical fields such as depth-of-field 3D imaging, zoom imaging, and robot vision systems, and in particular to a focal length-adjustable lens based on a dielectric elastomer driver and a preparation method thereof. Background technique

[0002] Soft robots are a new type of bionic continuum robots composed of soft-actuated materials. Compared with traditional rigid-body robots, soft-body robots have the characteristics of high structural softness, good environmental adaptability, strong affinity, diverse functions, and can greatly change the body shape. They have broad research and application prospects in unstructured environments. . It is a trend in the future to develop soft robots that can achieve more complex deformation and motion, and can be reprogrammed to adapt to environmental changes.

[0003] For soft robots, embedded flexible actuators are one of the most important components, driven by them, soft robots can co...
