1. Garmin’s upcoming “Muscle Battery” feature aims to analyze muscle oxygen saturation and sports performance metrics using specialized algorithms.
2. It likely requires dedicated hardware, such as a near-infrared spectroscopy (NIRS) sensor, which would be separate from current Garmin wearables.
3. The feature might be integrated into existing devices as a display function but may necessitate new hardware placed directly on muscles.
4. Garmin has shown interest in muscle-related metrics through surveys and concept ideas like Neuromuscular Readiness Score and Muscle maps.
Garmin’s New Muscle Battery Feature Might Be Coming Soon
So there is this new thing that Garmin was working on called Muscle Battery, and it sounds pretty cool kinda like a health tech upgrade. It was just recently spotted in a trademark registration filed at the USPTO, somewhere around mid-February 2026, with serial number 99661177. What it is supposed to do, is kinda like a software that captures, processes, and analyzes muscle oxygen saturation, or sometimes related to sports performance, using some special algorithms, according to the official description.
What We Know About The Technology
Now, this Garmin Muscle Battery is meant to be sold as part of personal electronic gadgets, like fitness trackers, smartwatches, and devices for health monitoring. It probably will need a particular hardware to work, such as a near-infrared spectroscopy sensor, better known as NIRS, to measure oxygen saturation in muscles (SmO2). As of now, there’s no Garmin wearable device with such a sensor, hinting that this might be a new product line entirely.
Hardware and Implementation
Plus, the sensor has to be placed directly onto the muscle group you’re trying to measure, which makes it a bit tricky for watches—probably not gonna fit on a regular Garmin smartwatch. Though you could see the data on a watch screen, the sensor itself will likely need to be attached directly to your muscles, maybe through a specialized strap or patch. And it’s probably not gonna be part of the upcoming CIRQA smart band after leaks earlier this year, since that was basically a wrist-worn thing, not designed for direct muscle contact.
Garmin’s Moving Toward Muscle Metrics
Interestingly, there are other signs Garmin is looking into muscle-related data for fitness. During a recent survey about strength training, they mentioned different “concept ideas,” like a Neuromuscular Readiness Score, a muscle recovery map, and something called Acute Strength Load. All these concepts suggest Garmin is seriously interested in personalized muscle metrics, but it’s still just in the idea stage for now.
Future Prospects and Uncertainties
It’s not clear yet if or when Garmin will officially release a wearable with this Muscle Battery feature. The trademark is still pending, so we’re in the wait-and-see phase. Overall, it seems Garmin is exploring some pretty advanced health tech that could potentially revolutionize how we track muscular health and performance someday soon.
