摘要： A protective layer for use on a sensor during a manufacturing process avoids damage to the sensor and keeps the sensor surface clean during lens fabrication. The protective layer includes a non-cross-linked, water-soluble polymer layer and an anhydrous, cross-linkable, methacrylate-based formulation layer, temporarily applied to a surface of the sensor. The protective layer may be used to protect the sensor during a manufacturing process by applying the non-cross-linked, water-soluble polymer layer and the anhydrous, cross-linkable, methacrylate-based formulation layer consecutively onto the surface of the sensor to form the protective layer; affixing the sensor to a substrate; fabricating a device that includes the substrate; and subsequently removing the protective layer from the surface of the sensor.

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 lens enclosure between the first and second encapsulation layers. 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.

摘要： Embodiments are disclosed of an eye-mountable device (EMD) including a lens enclosure including an anterior layer and a posterior layer sealed to the anterior layer. An anterior electrode is disposed within the lens enclosure on a concave side of the anterior layer, a posterior electrode is disposed within the lens enclosure on a convex side of the posterior layer, and an electrochromic element is disposed across a central region of the lens enclosure, wherein the electrochromic element separates the anterior electrode from the posterior electrode within the central region.

摘要： An eye-mountable device includes a flexible lens enclosure, anterior and posterior flexible conductive electrodes, and an accommodation actuator element. The flexible lens enclosure includes anterior and posterior layers that are sealed together. The anterior flexible conductive electrode is disposed within the flexible enclosure and across a center region of the flexible lens enclosure on a concave side of the anterior layer. The posterior flexible conductive electrode is disposed within the flexible enclosure and across the center region on a convex side of the posterior layer. The accommodation actuator element is disposed between the first and second flexible conductive electrodes. The anterior and posterior flexible conductive electrodes are transparent and electrically manipulate the accommodation actuator element.

摘要： Techniques and mechanisms for providing an eye-mountable device including an accommodation actuator. In an embodiment, fabrication of the eye-mountable device includes sealing layers of enclosure material to form a lens enclosure comprising a pinch-off region where the layers of enclosure material physically contact one another. The accommodation actuator includes a liquid crystal layer disposed between the layers of enclosure material in a central region around which the pinch-off region extends. In another embodiment, electrodes are disposed in the central region each between the liquid crystal layer and a respective one of the layers of enclosure material. The liquid crystal layer isolates the electrodes from one another in the central region.
