Have we simply had a glimpse of the place Whoop’s {hardware} might be heading subsequent? A newly granted patent from the corporate presents an fascinating take a look at a doable body-worn machine, with diagrams displaying a pressure-sensitive sensor strap designed for placement past the wrist. The submitting combines optical sensing with drive measurement and factors towards deeper physiological monitoring, together with muscle oxygen insights.
A sensor designed for various components of the physique
One diagram exhibits the machine positioned on the higher thigh, whereas one other highlights use throughout the chest, arm and waist. Chances are you’ll be questioning – why would Whoop need the machine worn somewhere else within the first place? The reply probably comes all the way down to knowledge high quality and the kind of physiological sign being measured.
The following Whoop machine?
Completely different areas of the physique provide very completely different insights. Bigger muscle teams such because the quadriceps can present a clearer view of muscle oxygen use throughout train, which might be notably helpful for working, biking and energy work. Against this, areas such because the chest or torso might provide extra secure readings for broader cardiovascular indicators and restoration metrics.
This means Whoop could also be constructing a system that adapts to the metric. That could be a notable shift from the standard smartwatch method, the place coronary heart fee, restoration and exercise monitoring are all constrained to a single location whether or not or not it’s the greatest place to seize the sign.
Muscle oxygen might be the true goal
The patent repeatedly factors towards combining optical sensing with strain knowledge to extract deeper physiological indicators. Some of the fascinating of those is muscle oxygen saturation, which has to this point been restricted largely to area of interest units and specialist sensors.
Putting a sensor on the thigh or arm makes rather more sense for the sort of measurement. It permits the machine to observe how muscle tissue are utilizing oxygen throughout effort, moderately than relying purely on coronary heart fee as a proxy for depth.
If Whoop strikes on this route, it may open the door to new varieties of coaching insights. As a substitute of solely monitoring pressure by cardiovascular response, the system may start to mirror how arduous the muscle tissue themselves are working and the way shortly they get better.
Strain sensing provides one other layer
One other necessary a part of the patent is using strain sensing throughout the strap.
Slightly than assuming the machine is worn accurately, the system can detect how tightly it’s pressed towards the pores and skin and regulate its readings accordingly. This has a direct influence on knowledge high quality, particularly for optical sensors, that are delicate to each motion and call consistency.

It additionally permits extra superior interpretations of the information. Adjustments in strain can have an effect on blood stream and tissue response, which might then be used alongside optical indicators to refine measurements.
The patent factors to greater than muscle oxygen
Whereas the muscle oxygen angle is arguably essentially the most eye-catching a part of the submitting, the patent itself factors to a broader set of physiological metrics.
Among the many indicators referenced are blood oxygen saturation, oxygenated and deoxygenated hemoglobin, and whole hemoglobin ranges. That means Whoop could also be exploring deeper tissue and blood stream evaluation.
The submitting additionally references tissue perfusion and blood stream associated indicators, which may doubtlessly be used to boost restoration and pressure insights. In sensible phrases, that might assist present a clearer image of how blood stream responds throughout train and the way shortly the physique returns to baseline afterwards.
There’s additionally point out of pulse waveform knowledge and pressure-based vascular measurements, which may assist extra superior cardiovascular metrics, together with refinements to blood strain pattern estimates. That’s notably notable given Whoop already presents Blood Strain Insights, suggesting this patent might level to future {hardware} designed to enhance the standard and reliability of these readings.
What this might imply for the following Whoop
In fact, this isn’t a confirmed product roadmap, so it needs to be handled as an early sign moderately than a direct preview of the following machine. What makes this submitting notably fascinating is that the patent drawings don’t seem to point out wrist placement, as an alternative specializing in different components of the physique.
That opens up the chance that this isn’t a direct substitute for the usual Whoop. As a substitute, it might be a separate machine designed to work alongside the core wearable, doubtlessly as a part of the corporate’s broader body-based monitoring ecosystem.
What provides this submitting weight is that, previously, just about all of Whoop’s patents have gone on to seem in real-world merchandise. Whereas that’s by no means a assure, it does make this really feel greater than only a theoretical idea on paper.
