Oura Launches Ring 5, The World’s Smallest Smart Ring With Upgraded Medical-Grade Health Tracking

  Global Release / May 28, 2026 - Finnish premium wellness wearable brand Oura officially unveiled the all-new Oura Ring 5, introducing the world's smallest and thinnest smart ring to the global market. Redesigned from the inside out, the Oura Ring 5 delivers revolutionary miniaturization, upgraded medical-grade sensing technology, and longer battery life, setting a new benchmark for invisible, all-day health monitoring.

     
1.Ultra-Compact & Lightweight Redesign for True All-Day Comfort
  The biggest highlight of the Oura Ring 5 is its industry-leading miniaturization. Compared with the previous-generation Ring 4, the new model reduces its overall volume by 40%, achieving a truly wearable, jewelry-style fit without compromising performance.
  Featuring a width of 6.09 mm and a thickness of 2.28 mm, the Ring 5 is slimmer and lighter than most traditional band rings, weighing only 2 to 3 grams depending on size. Built with premium medical-grade titanium, the device is hypoallergenic, scratch-resistant, and waterproof up to 100 meters, supporting daily wear, sports, swimming, and outdoor activities.
  Available in four classic finishes - Silver, Black, Gold, and Rose Gold - and sizes 6 to 13, the Ring 5 delivers a minimalist, low-profile design that seamlessly fits everyday, business, and lifestyle scenarios.
2.Upgraded Hardware: Smaller Size, Stronger Performance
  To achieve extreme miniaturization, Oura completely restructured the internal mechanical layout, sensor modules, and battery architecture. Equipped with a brand-new 12-channel high-precision sensing system, the Ring 5 integrates infrared PPG sensors, continuous body temperature detectors, and 3-axis IMU motion sensors, ensuring more accurate biometric data across all skin tones and finger sizes.
  Despite its ultra-slim body, the Ring 5 achieves improved battery performance, offering6 to 9 days of battery life on a single charge. A 20-minute quick charge delivers full power, and Qi wireless charging support enables convenient daily use. The optional portable charging case provides up to 30 days of standby power, perfect for travel and business trips.

  The flagship new feature, Health Radar, brings industry-leading sleep and cardiovascular monitoring. It continuously tracks nighttime blood pressure trends and breathing patterns during sleep, helping users identify potential cardiovascular risks and sleep breathing disorders at an early stage.
  In addition, the Ring 5 optimizes its sleep algorithm to version 4.0, accurately analyzing deep sleep, REM sleep, and light sleep cycles. It also provides 24/7 real-time tracking of heart rate, blood oxygen, body temperature, heart rate variability (HRV), and stress levels.
  Tailored for diverse user groups, the new generation adds specialized tracking functions including GLP-1 medication monitoring, menstrual cycle prediction, and menopause health insights. Users can also build personal health archives and access professional online medical consultation services, forming a complete closed-loop health management system.
