Abstract

The invention discloses an eye sensor and a preparation method thereof. The eye sensor comprises a corneal contact lens and a first interdigital capacitor, a second interdigital capacitor, a first inductive coil, a second inductive coil, and a channel resistor encapsulated in the corneal contact lens. The preparation method of the eye sensor according to the invention includes the following steps:(a) photoetching a graphene channel on a metal substrate; (b) removing excess graphene; (c) fixing glucose oxidase on the graphene; (d) photoetching an electrode pattern; (e) preparing an electrode;(f) repeating the above steps to produce electrodes of the interdigital capacitor and the inductive coil, and the channel resistor; (g) spin-coating and curing a flexible material on the electrode; (h) transferring the electrode; and (i) performing encapsulating. The eye sensor can realize 24-hour real-time dynamic monitoring of various health parameters such as intraocular pressure, eye temperature and tear glucose, and obtain more accurate intraocular pressure data by correcting the thermal expansion coefficient through the eye temperature, and has a simple structure, mature and easy processand low preparation cost.

Description

technical field [0001] The invention relates to an eye sensor and a preparation method, in particular to a wireless passive wearable eye sensor capable of real-time monitoring of intraocular pressure, eye temperature and tear sugar and a preparation method for 24 hours. Background technique [0002] Glaucoma is one of the three major blindness diseases that cause blindness in humans, with an incidence rate of 1% in the general population and 2% after the age of 45. Pathological elevated intraocular pressure and 24-hour intraocular pressure fluctuations are the main ways to diagnose glaucoma and judge the progress of glaucoma. Existing tonometers are all point-type measurements. During the 24-hour intraocular pressure measurement process, doctors often require patients to measure intraocular pressure at 5, 7, 10, 14, 18, and 22 o'clock respectively. When this method is used to diagnose glaucoma, it is impossible to obtain accurate intraocular pressure fluctuation data during...
