WHOOP could possibly be taking its subsequent well being step into glucose monitoring

A newly printed WHOOP patent utility describes a wrist-worn system that might estimate glucose focus with out puncturing the pores and skin, utilizing gentle, tuned optical filters and two separate sensors. The submitting reveals the {hardware} inside a WHOOP-style band, though it additionally covers patches, clothes, earbuds and a number of other different wearable codecs.

The patent utility, titled Glucose Monitoring, was printed on July 16 by the USPTO, below the quantity US 2026/0198807 A1. WHOOP filed it in January 2026, claiming precedence from a provisional utility submitted one 12 months earlier.

How WHOOP’s glucose sensor would work

The proposed system shines chosen wavelengths of sunshine into the wearer’s tissue. Glucose absorbs some wavelengths otherwise from others, permitting the wearable to search for adjustments that will correspond to glucose focus.

The submitting describes WHOOP utilizing two optical channels for this. One sensor measures wavelengths related to glucose absorption, whereas a second data a reference spectrum. The software program compares the 2 readings and calculates glucose focus from the ensuing ratio.

That reference measurement may assist filter out a few of the background noise that makes optical glucose sensing so tough. Skin thickness, hydration, motion, temperature and different molecules can all change the quantity of sunshine reaching a sensor.

The utility additionally describes utilizing quantum dots or different tightly managed gentle emitters. An optical layer containing glucose, or one other materials with related absorption traits, may present an extra reference sign contained in the sensor itself.

The patent covers way more than a wristband

The essential drawings present a screenless wrist-worn machine that appears related in appears with WHOOP’s current strategy. Sensors sit in opposition to the pores and skin, whereas the wearable communicates with a telephone and distant servers for additional evaluation. So no main adjustments there.

But the corporate has stored the broader claims versatile. The expertise may seem in bicep bands, patches, fingertip units, earbuds, eyewear, headbands and sensible clothes with a number of detachable sensor modules.

That breadth doesn’t imply WHOOP plans to fabricate each a kind of merchandise. Patent functions generally cowl quite a few configurations in order that opponents can’t simply use the identical sensing methodology in a barely completely different type.

The patent doesn’t present how this info would seem contained in the WHOOP app. It additionally offers no indication that WHOOP 5.0 or WHOOP MG accommodates the required optical {hardware}, so this appears extra like work for a future machine than a dormant characteristic ready to change on.

Accuracy stays the true problem

Wearable firms have pursued non-invasive glucose sensing for years, however turning a weak optical sign into dependable glucose readings stays tough. Detecting a broad development is one factor, whereas producing numbers that individuals can belief for medical selections is one thing else solely.

WHOOP’s reference channel and calibration strategies seem designed to handle a part of that drawback. However, the patent supplies no medical accuracy figures, error margins or testing outcomes.

It can also be unclear whether or not WHOOP needs to provide medical-grade glucose measurements or a broader wellness characteristic that tracks relative adjustments. The second choice may arrive sooner, notably if the corporate avoids presenting the readings as a substitute for a standard glucose monitor.

For now, this stays a patent somewhat than a product announcement. Still, a lot of the WHOOP patents we now have lined previously have finally translated into real-world merchandise or options, so this one is price taking critically.

What is obvious is that the corporate is trying past the measurements it affords at present. Another current patent describes a sensor that could possibly be worn on completely different components of the physique, with muscle oxygen monitoring among the many extra fascinating concepts. Add glucose monitoring to the combination and it appears WHOOP is exploring a a lot wider set of well being indicators
