Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0043] Such as figure 1 and figure 2 As shown, the bionic flexible lens of the present invention includes: a fixed frame 1 , an elastic fixed film 2 and a deformation cavity 3 .

[0044] The fixed frame 1 is circular, with a diameter of 10 cm, and is made of acrylic material; the elastic fixed film 2 is two dielectric elastomer films 31 stretched on the fixed frame 1, and the periphery of the two dielectric elastomer films 31 are mutually connected by silica gel. Bonding, the middle of the two dielectric elastomer films 31 encloses the deformation cavity 3 . The bonded part of the dielectric elastomer film 31 is used as the elastic fixing film 2 to fix the deformation cavity 3 on the fixing frame 1 .

[0045] The dielectric elastomer film 31 is the VHB film of 3M Company. It is stretched on the fixed frame 1 and undergoes equibiaxial pre-s...

Abstract

The invention discloses a bionic flexible lens capable of automatically zooming and application. The bionic flexible lens includes a deformation cavity which is surrounded by two transparent or locally transparent dielectric elastomer thin films which are connected; a transparent flexible conductor that warps the outer surface of the deformation cavity; and a transparent conductive liquid which is sealed in the deformation cavity and enables the two dielectric elastomer thin films to bloat. The bionic flexible lens provided by the invention is made of flexible intelligent material, does not contain a complicated mechanical structure, and can realize flexible adjustment of the focal length through intrinsic strain of the flexible intelligent material; the zooming range of the bionic flexible lens is relatively wide, and the bionic flexible lens can be used as an artificial lens, and can also be used as in an optical imaging system; and the bionic flexible lens is simple in structure, and is far lower in manufacturing cost than the prior art.

Description

technical field [0001] The invention relates to the fields of optics and bionics, in particular to an automatic zoom bionic flexible lens and its application. Background technique [0002] According to statistics, the number of visually impaired people in my country is about 14 million, accounting for 1% of the total population. At the same time, the existing medical technology is facing some challenges in restoring vision, a large part of which comes from the lack of hardware. That is to say, it is difficult to manufacture visual structures such as lenses and retinas that are highly compatible with the human body with existing technologies. Therefore, researchers have turned their attention to the field of bionics, imitating the working principle of biological eyes, and making some progress in vision restoration technology. [0003] The existing intraocular lens mainly uses artificial synthetic materials such as silica gel, polymethyl methacrylate, and hydrogel to make a s...
