Abstract
An augmented reality system including a necklace and a contact lens display can be used to project information from the contact lens display onto the retina of the wearer's eye. In one example, the necklace generates a time-varying magnetic field (TVMF) that provides energy and information to the contact lens display via inductive coupling. The necklace can be configured to decrease the amount of energy absorbed by the body of the wearer and increase power transfer to the contact lens display. The necklace includes a conductive loop and one or more bucking loops that are positioned to increase transmitted energy while reducing the amount of energy absorbed by the human body. The amount of current travelling in one direction through the loops of the necklace is greater than the amount of current travelling in the opposite direction through the loops of the necklace. The necklace can include any number of signal generators and winding patterns for the loops.
