Smart contact lens and eyelid patch

Materials Science Although chronic ocular surface inflammatory diseases are prevalent, appropriate devices to monitor the disease condition quantitatively in daily life have not yet been developed. Point-of-care devices for controlled therapy in response to biosensing are also not available. Jang et al. report wearable devices for the monitoring and treatment of ocular surface inflammation. A smart contact lens using graphene biosensors integrated with wireless communication units monitors a biomarker of ocular inflammation and sends data wirelessly to a mobile device. A transparent skin patch mounted on the eyelid provides feedback thermotherapy, which is controlled by the mobile device through wireless communication. In vivo applications to animal and human subjects confirmed the potential of this wearable health care platform. Sci. Adv. 10.1126/sciadv.abf7194 (2021).
