`Oura Ring 2 Teardown - iFixit 7/10/25, 2:12 PM

`
`Introduction
`
`The Oura Ring has been around for a while now, but it didn’t become mainstream news until the NBA got one for each player
`to try to detect early signs of COVID-19. There are a lot of questions about the effectiveness of the Oura Ring, but one
`thing's for sure: it's jam-packed with a lot of tech for such a small device.
`
`The Oura Ring is interesting for a whole basket of reasons. If you're a sports fan, you're probably rooting for the Oura Ring 2
`to work so we can have basketball back in our lives. If you're a biohacking fan, you might be interested because it monitors
`your vitals and analyzes your sleep. We've seen a lot of gimmicky devices over the years, but it's in our blood to understand
`how new tech works—so we took it apart to find out what tech is hiding underneath that .25 OZ of titanium.

`
`@ This is primarily a video teardown, but
`intrepid iFixit community members
`have also submitted their own
`analyses. One reader in particular
`spent hours attempting to reverse
`engineer the Oura Ring 2 through the
`video, datasheets, and X-rays, and
`shared the following:
`
`® The two IR LED drivers should be
`the same type, one for each IR
`LED.
`
`- ® There's likely an operational
`
`amplifier for signal conditioning for
`the photo diode before the signal
`is sent to the microcontroller. (This
`is commonly done with these type
`of photo diode based health
`meters.)
`
`® |[f this is not a microcontroller, it
`could be a temperature sensor
`(not a thermistor).
`® A wireless charging IC, predicted
`based on its surrounding
`components and location.
`® And finally, a battery fuel gauge IC
`for probably determining battery
`health.
`
`® Based on all this, the second image
`shows the predicted block diagram.

`
`D Wow, | didn’t even know smart rings existed. | also think that it'd be much easier to service if the titanium shell came off in
`two halves so nothing would have to be bent to service the electronics.

`
`C] Is it possible for you to share SMD Markings on all the devices?
