Abstract
The present disclosure relates to a smart contact lens for diabetes diagnosis in which a diabetic diagnosis sensor is composed of platinum-plated electrodes, and a driving system using the same. The smart contact lens of the present disclosure is easy to mass-produce, has good wireless power transfer efficiency due to high electrical conductivity, may perform good communication with an external driving board, and may perform physically and electrochemically stable driving.
Claims9
A smart contact lens for diabetes diagnosis, comprising:
- a platinum-plated electrode including an electrically conductive layer and a reaction layer;
- and
- a porous hydrogel including a nanocatalyst,
- wherein the reaction layer includes platinum (Pt),
- wherein the nanocatalyst comprises gold-platinum bimetallic nanoparticles with thiolated hyaluronic acid, and
- wherein the porous hydrogel is prepared through:
- preparing a base solution comprising polyvinyl alcohol (PVA), chitosan, bovine serum albumin (BSA), and glucose oxidase (GOx);
- adding magnesium particles and the nanocatalyst to the base solution to prepare a mixture, drop casting and drying the mixture;
- drop casting a solution comprising a glutaraldehyde and crosslinking the mixture;
- and
- removing the magnesium particles.
