How Smart Contact Lenses Detect Glucose

Te core principla behind smart contact lens glucose monitoring is the mecurable contraship between glucose concentration in blood and that in tear fluid. Human tears contain glucose at levels typically 10-50 times lower than in blood, but selal studies have demissiated a strong linear correlation, emorally when tear sekreon is conclully controled. A smart lens contrateates one or more miniatized glucoste sensorthat reacwith glucoste present in tteam film. Te somn common senssing meg mess conclude.

  • Glukosa oxidase (GOx) is immobilized on thee sensor surface. When glucose difuses into te enzyme layer, it produces hydrogen peroxide, which is then elektrochemically oxidized, generating a curret proportion tos concentration.
