Eye-mountable device to provide automatic accommodation and method of making same

摘要

An eye-mountable device (EMD) includes a lens enclosure, liquid crystal material, first and second electrodes, a substrate, and a controller. The lens enclosure includes a first encapsulation layer and a second encapsulation layer sealed to the first encapsulation layer. The liquid crystal material is disposed across a central region of the lens enclosure. The first electrode is disposed within the lens enclosure between the first encapsulation layer and the liquid crystal material. The second electrode is disposed within the lens enclosure between the second encapsulation layer and the liquid crystal material. The substrate is disposed within the EMD. The controller is disposed on the substrate and electrically coupled to the first and second electrodes to apply a voltage across the liquid crystal material.
