Abstract
An augmented reality system can include an electronic contact lens, a power source, and a head wearable object. The contact lens, power source, and head wearable object all include corresponding conductive loops to enable wireless transfer of power between the power source and the contact lens. When current is driven through a conductive loop of the power source, the power source generates a primary time-varying magnetic field. The primary time varying magnetic field induces a current in a conductive loop of the head wearable object. The induced current in the head wearable object generates a secondary time-varying magnetic field. Both the primary and secondary time varying magnetic field generate a current in the conductive loop of the contact lens. The system can also include a haptic feedback system that allows information to be communicated between elements of the system.
