Wearables that read your blood: rings, CGMs and the longevity pitch at CES 2027

Wearables that read your blood. The health corner of CES used to be step counters and a massage chair. In 2026 it was one of the biggest zones in the show: 76 smart-ring exhibitors by one count, continuous glucose monitors sold over the counter, and a “longevity” pitch on every other banner. Here is what was real and what to watch for in January.

Rings, rings, rings

The smart ring went from an Oura monopoly to a crowd. Most of the new rings do the same core job: heart rate, blood oxygen, sleep staging and stress, in a band you forget you are wearing. The J-Style JCRing is a fair example of the baseline. RingConn teased a Gen 3 with a new “blood-related” feature it would not fully name on the floor. And the most interesting ring at the show was not a health ring at all: Even Realities’ R1 is an input device for its G2 smart glasses, which tells you where rings go next. The ring becomes the remote for whatever is on your face.

Glucose without a needle, mostly

Abbott showed its biowearable lineup, including the FreeStyle Libre and the over-the-counter Lingo continuous glucose monitor, which is a small sensor on the arm, not a ring. Withings is adding glucose data to its ecosystem through a partner in metabolic tech and is leaning hard on longevity as the story. Nobody we could verify showed a ring that measures glucose from the finger at CES 2026. Circular announced plans for glucose trends on its Ring 2 at the 2025 show, with a 2026 target, and we have not confirmed it shipped. Treat any “glucose ring” at CES 2027 as a claim until a clinic says otherwise.

Why the longevity word is everywhere

Because it sells. “Track your sleep” is a feature. “Live longer” is a reason to spend 400 dollars and a monthly subscription. The products are often the same sensors with a new dashboard. That is not necessarily a scam; good sleep and heart data over years really is useful. It just means you should look at what the device measures, not what the banner promises.

The skate angle

Nobody at CES makes a wearable for people who fall down for fun. Our wish list is boring and specific: a ring or band that survives a slam, reads recovery honestly, and does not need charging mid-session. The surf version is the same with saltwater. If a booth has that, it gets a FUNN hologram.

What we are looking for in January

  • A blood-pressure or glucose reading from a ring, with a regulatory clearance behind it, not a wellness disclaimer.
  • Rings as controllers: the G2-and-R1 idea spreading to other glasses and to TVs.
  • Subscription honesty. We will ask every booth what the device does when you stop paying.
  • Battery life measured in weeks.
