Intelligent contact lens containing flexible circuit and preparation method thereof

Abstract

The invention discloses an intelligent contact lens containing a flexible circuit and a preparation method thereof.The intelligent contact lens comprises a first packaging layer, the flexible circuit, a second packaging layer and a contact lens layer which are sequentially arranged, and the second packaging layer is located on the side, opposite to the eyes, of the contact lens layer; the first packaging layer and the second packaging layer are made of the same material which is an elastomer material. According to the invention, no extra substrate material is introduced, the material adopted by the packaging layer has high stretchability and bendability, and the whole preparation process can be well integrated into the production process of the current contact lenses, and has the potential of large-scale production.

Description

technical field [0001] The invention relates to the technical field of contact lenses, in particular to an intelligent contact lens containing a flexible circuit and a preparation method thereof. Background technique [0002] As a special human-machine interface, smart contact lenses are the closest device platform to the human eye. Using advanced technologies such as functional materials and micro-nano electronics, smart contact lenses can detect and track physiological information of the eye, such as intraocular pressure, ocular surface heat, electrolyte content, etc., thereby providing diagnostic basis and treatment assistance for clinical medicine; , Smart contact lenses also have the potential to become a new generation of human-computer interaction platform, realizing a series of visual experience enhancement functions including augmented reality, virtual reality, smart office, etc. [0003] However, in order to realize the above-mentioned rich and complex functions, ...

Problems solved by technology

However, there are many shortcomings in such a process: first, the mechanical modulus of the newly introduced substrate does not match the contact lens, which has a great impact on the stability and wearing comfort of the lens; second, in the production process of the contact lens There is a process in which the circuit changes from a plane to a spherical surface. It is difficult to determine the position and shape, and it is prone to misalignment problems, which affects the realization of functions and poor device consistency. Higher demand, low industrialization potential

[0004] In addition to the inherent problems of the process, functional circuits require a dry operating environment, and contact lenses require sufficient moisture content, so contact lenses and functional circuits have a core contradiction between moisture content and dry operating environment
