A system (100) for monitoring eyelid motion includes an eyelid-mounted device (10) attached to an external surface of an eyelid. The eyelid-mounted device (10) includes a sensor (14, 16, 18) configured to sense motion or deformation of the eyelid. The sensor may be a motion sensor (14, 16) such as an accelerometer, or a deformation sensor (18) such as a piezoelectric film. A processing system (20, 48, 50, 62) receives signals from the sensor and processes the signals to determine a parameter relating to motion of an eye and/or the eyelid. The processing system may be onboard the eyelid-mounted device (10) or may be external to the eyelid-mounted device.

A system includes an ocular device (10) for deployment in or on an eyeball, and an external device (12). The external device has an electrically-actuated energy-transmitting component (16) for mounting in proximity to the eye, and preferably on an external surface of an eyelid of a user so as to move together with the eyelid. Driver circuitry (22) actuates the energy-transmitting component to transfer energy wirelessly to an energy receiver of the ocular device. Some implementations employ near-field resonant coupling between the external device (12) and the ocular device (10), and support data transfer therebetween, optionally via modulation of the transferred power.
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.

Apparatus for harvesting energy from relative motion of body parts, particularly an eyeball and an eyelid
A system for providing electrical energy to an implanted device or to a device attached to a body. The system includes one or more permanent magnets attached to or implanted in a first body part and one or more inductor(s) attached to or implanted in a second body part. The inductor(s) are electrically couplable to the implanted device for providing the implanted device with electrical currents flowing in the one or more inductor(s) in response to changes in the position and/or orientation of the permanent magnet(s) relative to the position and/or orientation of the inductor(s). The system may include a current rectifier for rectifying electrical currents provided by the inductor(s). The system may also include a charge storage device electrically coupled to the current rectifier for storing electrical energy received from the current rectifier.
