Apple patent reveals earbuds with Biometric sensors
What you need to know
- Apple patent published today reveals earbuds with biometric sensors.
- Could be used to measure heart rate, blood volume and respiratory rate.
- Earbuds could be interchangeable between ears.
A patent filed by Apple and published today has revealed how Apple is exploring the use of biometric sensors within earbuds.
The background of the patent states:
The patent details how earbuds could be configured to include biometric sensors. One of these sensors could be pressed up against the tragus in the ear to allow the taking of biometric measurements. One such sensor could be a PPG sensor, which uses a pulse oximeter to illumate a patch of skin to measure changes in light absorption of the skin. Such a sensor can measure changes in the light absorption as caused by profusion of blood, allowing the earbuds to measure heart rate, blood volume and respiratory rate. With a slight variation to the light emitted, it could even measure VO2 max (the maximum amount of oxygen absorbed by the body).
The patent also states:
The sensors within the earbud, according to the patent would also be able to determine which ear your earbud has been placed in, and alter its operation accordingly.
So there you have it, Apple could one day release earbuds that could measure your blood volume, heart rate, VO2 max, respiratory rate and stress.
