POSITION-SENSING CONTACT LENSES

摘要

The subject matter of the disclosure relates generally to a MEMS-based position-sensing system and lenses, for example, contact lenses and intra-ocular lenses, manufactured with the position-sensing system employing one or more angular and/or linear accelerometers and/or pressure transducers and methods for detecting position and motion of an eyeball and/or head utilizing the position-sensing contact lenses.

主权项

1. A system for sensing ocular position, the system comprising:
two or more structures (e.g., toroidal fluid-filled channels serving as angular accelerometers) integrated within a lens (e.g., a contact lens or intraocular lens), each of the structures defining a unique plane; one or more motion-sensing elements (e.g., inertial elements such as microbubbles) associated with (e.g., integrated within) each of the two or more structures; and one or more detectors (whether integrated within the lens, e.g., semi-permeable membranes located within the toroidal fluid-filled channels, or located external to the lens, e.g. a camera, CCD, or other sensor located outside the lens) for identifying a position and/or movement (e.g., angular acceleration) of each of the one or more motion-sensing elements within the respective structure.
