Abstract

Continuous intraocular pressure (IOP) monitoring is crucial for glaucoma management. This paper presents a novel liquid metal-based LC contact lens sensor that significantly improves sensitivity compared to existing technologies. The sensor uses a stretchable inductive and capacitive design, allowing for simultaneous response to IOP changes. Modeling, fabrication, and extensive testing demonstrate the device's reliability, high signal quality, and threefold increase in sensitivity, surpassing current state-of-the-art contact lens sensors.
