OCULAR SYSTEM WITH ENHANCED INDUCTIVE COUPLING

An ocular system includes an ocular device (), having a coil (), for deployment in or on the eyeball, and an auxiliary device, including a coil (), integrated into a patch () 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 () has windings of conductive wire about a magnetic core () configured so as to define a primary direction of induced magnetic field through the auxiliary-device coil that is tangential to the skin surface.
