  • Wireless scleral search coil including systems for measuring eye movement and methods related thereto
    Patent number: 7967439
    Abstract: Featured is a wireless scleral search coil that includes one or more passive, resonant coils and in a particular embodiment two orthogonal, passive, resonant coils, where each coil resonates at a different frequency. Each resonant coil includes a coil-capacitor circuit, each circuit being configured to resonant at a different frequency. Such a wireless scleral search coil is disposed within a biocompatible material that is shaped to conform and rest upon the eye of a subject. Also featured are system including such a wireless scleral search coil, one or more transmitter coils, an assembly of one or more receiver coils and a calculating sub-system for processing signal data to obtain eye measurement information.
