OCULAR SYSTEM WITH ENHANCED INDUCTIVE COUPLING

Abstract

An ocular system includes an ocular device (10), having a coil (16), for deployment in or on the eyeball, and an auxiliary device, including a coil (18), integrated into a patch (12) for deployment on an eyelid or adjacent to the eye. The auxiliary device also includes driver circuitry connected to the auxiliary-device coil, for wirelessly transferring energy and/or exchanging data between the auxiliary device and the ocular device via inductive coupling between the auxiliary-device coil and the ocular-device coil. The auxiliary-device coil (18) has windings of conductive wire about a magnetic core (30) configured so as to define a primary direction of induced magnetic field through the auxiliary-device coil that is tangential to the skin surface.
