Abstract
Recent developments in wearable devices which can perform direct detection of various biomarkers have attracted enormous interests in the global medical market. Especially, contact lens has been spotlighted as an ultimate platform due to abundant biomarkers in the eye. Among the biomarkers, intraocular pressure (IOP) is important biological information in eye health. Continuous measuring of the IOP is required to treat glaucoma or prevent side-effects after ophthalmological surgery. Herein, I fabricated smart contact lenses integrated with a strain gauge which detect the IOP by measuring the change of radius corneal radius of curvature. The smart contact lenses are highly sensitive by using single-crystalline silicon nanoribbons for sensing the strain. Also, the sensing results are transmitted by the wireless system integrated on the lenses. The fabricated smart contact lenses were demonstrated its sensing performance with the in-vitro test using eyeballs. Moreover, to show the potential of the lenses for clinical application, IOP of rats who operated transplant surgery onto their eye was measured for 9 weeks. These results represent that the smart contact lenses suggest a promising strategy toward wearable electronics for ocular diagnostics.
