Wearables innovation: health-grade sensors, smart rings, and new revenue
Wearables are rebounding as health-grade sensors and new form factors push the category beyond step counting. With smart rings joining smartwatches and hearables, companies are racing to blend clinical validation, ecosystems, and subscription services—reshaping the business of connected wellness.
Market reacceleration and shifting mix
In the Wearables sector, After a period of consolidation, wearables are back in growth mode as consumers upgrade aging devices and new form factors expand the addressable market. Shipment volumes returned to the hundreds of millions, with smartwatches, hearables, and now rings forming the core of demand, according to industry data. Apple, Samsung, Huawei, Xiaomi, Garmin, Fitbit (Google), and rising specialists like Oura and Whoop are competing across price tiers and use cases, from performance tracking to passive health monitoring and safety.
The mix is tilting toward devices that deliver more actionable insights—sleep staging, recovery scores, continuous HRV, and ambient stress—with even entry-level products gaining features that previously sat at the high end. Hearables remain the volume engine, but smartwatches and rings are pulling higher engagement thanks to long wear time and seamless coaching prompts. As ecosystem lock-in grows, vendors are leveraging cross-device continuity (phones, earbuds, watches) to reduce churn and raise lifetime value.
Hardware improvements are also enabling a fresher upgrade cycle. New sensor stacks, low-power silicon, and tighter firmware–cloud loops are producing more accurate insights with less battery penalty. That matters in form factors like rings, where industrial design constraints are extreme and “forget-you’re-wearing-it” experiences drive adherence.
From steps to biomarkers: clinical validation and regulation
The category’s most consequential shift is toward health-grade capabilities. Wearables are increasingly bridging wellness and regulated care, with over-the-counter hearing aids accelerating mainstream adoption since the U.S. finalized the OTC pathway in 2022, per the FDA. Remote detection of arrhythmias, fall risk alerts, and ambient activity/sleep signals are being integrated into care plans and employer wellness programs.
Large-scale studies have bolstered confidence. In the Apple Heart Study published in the New England Journal of Medicine, researchers analyzed data from over 400,000 participants to evaluate smartwatch notifications for atrial fibrillation, helping validate the potential of wrist-based screening and follow-up pathways, according to peer-reviewed research. While algorithms for blood pressure and sleep apnea are still maturing—and regulatory pathways vary—clinically oriented features are steadily moving from pilot to scaled deployment.
