Embodiment Construction

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

[0043] Such as figure 1 with 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, which is a circular ring with a diameter of 10cm, is made of acrylic material; the elastic fixed film 2 is two dielectric elastomer films 31 stretched on the fixed frame 1, and the outer periphery of the two dielectric elastomer films 31 are mutually connected by silica gel. The two dielectric elastomer films 31 are bonded together to form a deformation cavity 3. The bonded parts of the dielectric elastomer films 31 serve as an elastic fixing film 2 to fix the deformation cavity 3 on the fixing frame 1.

[0045] The dielectric elastomer film 31 is a VHB film made by 3M. When stretched on the fixed frame 1, it undergoes equi-biaxial pre-stretching, the equi-biax...

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 field of optics and bionics, in particular to a bionic flexible lens with automatic zoom and its application. Background technique [0002] According to statistics, there are about 14 million people with visual impairment in my country, accounting for 1% of the total population. At the same time, the existing medical technology is facing some tests in terms of restoring vision, and a large part of it comes from the lack of hardware. That is, the existing technology is difficult to produce a lens, retina and other visual structures that are highly compatible with the human body. Therefore, researchers set their sights on the field of bionics and imitated the working principles of biological eyes, which made some progress in visual restoration technology. [0003] The existing intraocular lens is mainly made of artificial synthetic materials such as silica gel, polymethyl methacrylate, hydrogel, etc., to produce a suitable focal le...
