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 minimize the amount of energy absorbed by the body of the wearer while maintaining power transfer to the contact lens display. In one example, the necklace includes multiple conductive coils generating constructively interfering TVMs to effectively transmit energy while reducing the amount of energy absorbed by the human body. In another example, the necklace includes a parasitic coil generating a destructively interfering TVMF and a magnetic shield to effectively transmit energy while reducing the amount of energy absorbed by the human body.
