In recent years, smart rings have made significant strides in both consumer markets and research environments. At CES 2025, we witnessed Circular unveil a smart ring capable of detecting atrial fibrillation (AFib), with Ultrahuman also introducing smart ring technology encased in exquisite gold and platinum.
Now, let’s take a look at Viv Health, a digital health startup from South Korea that has introduced the Viv Ring. This device sets itself apart not just with its sleek appearance but also with its innovative feature: personalized AI-generated sleep sounds.
The Viv Ring covers all the essential features you’d expect from a typical smart ring, including heart rate monitoring, variability, stress level analysis, blood oxygen level checks, physical activity tracking, and sleep analysis.
But the Viv Ring doesn’t stop there. It analyzes all the biomarker data it collects and utilizes AI algorithms to produce customized sleep sounds, a feature the company refers to as “generative sleep aid sound technology.”
The ring generates soothing sounds reminiscent of ocean waves, birds chirping, deep-sea ambiance, and rainfall. Rather than relying on generic audio tracks, Viv combines these sounds with monaural and binaural tunes in an effort to promote improved sleep quality.
Would you like some AI-generated sounds for your sleep?
Viv asserts that its technology thoroughly evaluates the entire spectrum of biosensing data, creating AI-driven audio tailored specifically to enhance sleep quality.
These claims are intriguing, given that scientific research has primarily examined the effects of white and pink noise as well as multi-audio stimulation on sleep. The findings, however, are somewhat mixed. Some studies suggest positive outcomes, while others indicate a more inconclusive viewpoint concerning sound’s impact on sleep quality.
Since Viv is leveraging generative AI to create tailored sounds, we venture into uncharted territory regarding sleep aids. The company also has plans for an enhanced version of the Viv Ring by the end of 2025.
A Pro model of the Viv Ring is anticipated to launch later this year, featuring continuous blood pressure monitoring and AFib detection — technology that is becoming increasingly common in wearables.
At CES, Novosound showcased a futuristic ultrasound sensor intended for blood pressure measurement, which is slated for inclusion in smartwatches and rings. Samsung has already adopted such technology, although with a PPG sensor for estimating blood pressure.
Viv Health is currently working towards obtaining necessary regulatory certifications and aims to make the Viv Ring available for purchase as soon as next month.
