Methods and Systems for Identification of an Eye-Mountable Device

摘要

An eye-mountable device includes a controller embedded in a polymeric material configured for mounting to a surface of an eye. The controller is electrically connected to an antenna included in the eye-mountable device. The controller is configured to: (i) receive an indication of an interrogation signal via the antenna, (ii) responsive to the interrogation signal, output a substantially unique identification sequence; and (iii) use the antenna to communicate the substantially unique identification sequence. The substantially unique identification sequence can then be used by external readers to associate the eye-mountable device with device-specific information without storing such information on the eye-mountable device.

1. An eye-mountable device comprising:
a transparent polymeric material having a concave surface and a convex surface, wherein the concave surface is configured to be removably mounted over a corneal surface and the convex surface is configured to be compatible with eyelid motion when the concave surface is so mounted; a substrate at least partially embedded within the transparent polymeric material; an antenna disposed on the substrate; a controller electrically connected to the antenna and configured to: (i) receive an indication of an interrogation signal via the antenna, (ii) responsive to the interrogation signal, output a substantially unique identification sequence; and (iii) use the antenna to communicate the substantially unique identification sequence.
