Health Trackers Shrink 40% to Blend In and Capture More Continuous Data

Summary
Oura’s new Ring 5 is 40% thinner than its predecessor, and Dexcom said in May it is cutting the size of its latest continuous glucose monitor by 50%.
That miniaturization is aimed at making trackers easier to wear all day, so users generate steadier streams of sleep, activity, diet and stress data.
More consistent use matters because most health features work passively: devices collect signals in the background, then phone apps and algorithms turn them into health summaries or condition alerts.
The shift also reflects a maturing market—more than 550 million people already own smartwatches—so companies are prioritizing discreet rings, earrings and other jewelry-like designs over visibly branded hardware.
The broader goal is an always-worn device that fades into daily life while building enough longitudinal data to support FDA-cleared detection features and, when needed, links to medical care.
