Contact lens with integrated pulse oximeter

摘要

Apparatus, systems and methods employing a contact lens having a pulse oximetry sensor to detect information indicative of a blood oxygen content and/or pulse rate of a wearer of the contact lens, are provided. In some aspects, a contact lens includes a substrate that forms at least part of a body of the contact lens and a pulse oximetry sensor located on or within the substrate that detects information associated with at least one of blood oxygen content or a pulse rate of a wearer of the contact lens. The pulse oximetry sensor comprises one or more light emitting diodes that illuminate a blood vessel of at least one of a region of an eye or an eyelid and a detector that receives light reflected from the blood vessel and generates the information.

1. A contact lens, comprising:
a substrate that forms at least part of a body of the contact lens; and a pulse oximetry sensor located on or within the substrate configured to detect information associated with at least one of a blood oxygen content or a pulse rate of a wearer of the contact lens, the pulse oximetry sensor comprising:
one or more light emitting diodes configured to illuminate a blood vessel of at least one of a region of an eye or an eyelid; anda detector configured to receive light transmitted through the blood vessel and generate the information, wherein the information includes a signal indicating an amount of light transmitted through the blood vessel;wherein the one or more light emitting diodes and the detector are positioned away from a center of the contact lens; the contact lens configured to maintain an orientation when worn on an eye such that the one or more light emitting diodes and the detector are not covered by an eyelid when the eye is open.
