Structural design of a smart contact lens with ultrathin MoS2 transistors-based serpentine mesh sensor system
(A) Schematic illustration of the different layers of smart contact lens structure attached to an eyeball. The dashed region highlights the gold-mediated mechanical exfoliation of monolayer MoS2.
(B) Optical image of the serpentine electrode and sensor structure.
(C) Photograph of the sensor layer transferred onto a dome-shaped PDMS substrate.
(D) Photograph of the system placed on an artificial eye.
(E) Illustration of the smart contact lens and the corresponding dimensions with human eyes.
