Abstract

CAPACITIVE SENSING CIRCUITS AND METHODS FOR DETERMINING EYELID POSITION USING THE SAME 5 The present disclosure relates to sensor systems for electronic ophthalmic devices. In certain embodiments, the sensor systems may comprise a first electrode configured to be selectively overlaid by one or more of an upper eyelid and a lower eyelid of a user, a second electrode configured to be selectively overlaid by one or more of an upper eyelid and a lower eyelid of a user, and a system controller cooperatively 10 associated with the first electrode and the second electrode to receive a capacitance measurement therefrom, the system controller configured to determine a position of one or more of the upper eyelid and the lower eyelid in spatial coordinates based on the capacitance measurement received from the first electrode and the second electrode. 15 Figure 1
