The latest: The tech giant was awarded a broad patent for a “wearable device with perspiration measuring capabilities” — greenlighting noninvasive hydration tracking for Apple Watch.
New Drip
Recognizing its role in performance, cognition, weight loss, and more, consumers are hydration-obsessed.
Removing the guesswork, microfluidic sensors are personalizing refueling:
Targeting endurance athletes, Nix and FLOWBIO measure real-time electrolyte loss through noninvasive skin patches.
Sweat patch makers WearOptimo and Epicore take on workers’ heat stress, with the latter recently landing investment to enter Asia.
Refining the process, hDrop launched a reusable, clip-on sweat monitor.
Drop in the bucket. But, Apple’s hydration feature is a threat to standalone sensors — and not for the first time.
Apple is zeroing in on noninvasive glucose monitoring for Apple Watch.
While it reformulates its patent-infringing SpO2 sensor, blood pressure and sleep apnea monitoring are expected this year.
Tying it all together, its planned AI health coach will synthesize the data for a comprehensive picture.
Punchline: Sweat tracking is the new step counting, and another likely spoke for Apple’s wrist-worn health hub.
We break down how fitness, wellness, and healthcare are converging — and what it means for business, culture, and capital.
