Title: ELECTRONICS EMBEDDED IN RIGID GAS PERMEABLE CONTACT LENSES
Abstract:
An eye-mountable contact lens (110, 210a) is provided that includes electronics (150, 160, 170) encapsulated within a rigid, gas-permeable polymeric material (120, 330b). The rigid, gas-permeable polymeric material (120, 330b) can be mountable to a corneal surface of an eye (fig 1C) or can be disposed on or within (fig 2A) a flexible polymeric material (220a) that is mountable to the corneal surface of the eye. The rigid, gas-permeable polymeric material (120, 330b) can provide structural rigidity and protection to the electronics (150, 160, 170) and/or can allow for long-term dry storage of a chemical sensor of the electronics (150, 160, 170). The rigid, gas-permeable polymeric materials (120, 330b) of the provided eye-mountable devices (110, 210a) can be formed by curing a precursor material (330a) on or around the electronics and subsequently removing portions of the polymeric material formed by the curing, e.g., to form a rigid, gas-permeable contact lens (110, 210a) that at least partially encapsulates the electronics (150, 160, 170) and that has a curved shape that is able to be mounted to a corneal surface of an eye (fig 1C).
