Abstract
An augmented reality system can include an electronic contact lens and a power source. The source generates a time-varying magnetic field which induces a time-varying current in conductive coils embedded in the electronic contact lens. The electronic contact lens uses the induced current to harvest power or to determine the orientation of the contact lens. The embedded conductive coils are positioned such that the AR system can harvest power and estimate the orientation of the eye at a variety of contact lens orientations. The conductive coils may be embedded within the contact lens at any number of positions and orientations. The embedded coils can encircle a portion of the contact lens and can collectively form an annulus within the contact lens. The conductive coils are embedded such that for at least three conductive coils, no two of the planes defined by the at least three conductive coils are parallel.
