Oura Ring 5 Patent Leak Reveals Built-In Blood Sugar Sensor That Apple and Samsung Failed to Perfect
A newly published patent filing from Oura Health suggests the upcoming Oura Ring 5 will feature a non-invasive blood glucose monitor—a game-changing health metric that has eluded tech giants like Apple and Samsung for years. According to the document, the ring uses near-infrared spectroscopy to measure glucose levels through the skin, eliminating the need for painful finger pricks. While Oura has not confirmed the feature officially, a leaked internal memo claims the sensor is already in final testing for a 2025 launch. Health experts are skeptical, noting that no consumer wearable has successfully delivered accurate continuous glucose monitoring without calibration. Social media is buzzing with speculation, but for now, treat this as unconfirmed—Oura's official press release on the Oura Ring 5 is expected next quarter.
