The wearable market is filled with smart rings that claim to monitor heart rate, sleep, SpO₂, and other vital signs. But if you look closely, you’ll find that most of them provide reference-level insights, not clinically trusted data.
They may track your trends, but when you want to know:
“Is my blood pressure healthy?” or
“Should I be worried about this heart rate?”
— They often can’t give a reliable answer.
Doni Ring is different.
We’ve built Doni Ring to be more than just a gadget — it’s a medical-grade cardiovascular monitoring tool, tested, validated, and trusted by real clinical standards
🩺 A Medically Certified Blood Pressure Monitoring System
Unlike most wearable devices, Doni Ring’s blood pressure system is not just smart — it’s registered as a certified medical device and has undergone clinical trials under national regulatory standards (NMPA).
That means:
- Our blood pressure readings are not estimates — they’re built on certified medical protocols.
- Our algorithms have been tested in clinical environments against standard upper-arm sphygmomanometers.
- We’ve validated accuracy across diverse populations, including individuals of different ages, genders, and health conditions.
In short, we measure accurately, and we measure reliably.
🧬 Advanced Sensors + Proprietary Algorithms = A Powerful Cardiovascular Engine
We didn’t just assemble off-the-shelf hardware. Doni Ring is fully self-developed, from sensors to signal processing algorithms. Here’s what powers our accuracy:
- 🔹 High-sensitivity PPG waveform capture
- 🔹 Multi-channel motion noise cancellation and dynamic correction
- 🔹 Cardiac Load Index (CLI) modeling
- 🔹 Systolic/diastolic blood pressure estimation algorithms
- 🔹 Time-domain, frequency-domain, and HRV-based trend prediction
This enables Doni Ring to become one of the very few rings on the market that can:
Continuously monitor blood pressure from your fingertip, non-invasively, with medical-grade precision.
🧑⚕️ Real Clinical Trials — Not Just Marketing Claims
Our clinical testing wasn’t symbolic — it was conducted under national Class II medical device certification requirements.
We followed the full process:
- Hospital IRB (ethics) approval
- Multi-center clinical trials
- Comparison with gold-standard electronic blood pressure monitors
- Double-blind analysis by physicians and statisticians
The result?
Doni Ring’s systolic and diastolic measurements showed minimal deviation from medical-grade upper-arm devices, fully meeting national medical accuracy standards.
When we say “medically accurate,” we mean it — and we’ve proven it.
💬 Final Word: In Health Monitoring, Accuracy Matters More Than Hype
The world of wearables is getting smarter, but “professional and trustworthy” is what truly matters.
Doni Ring’s cardiovascular system isn’t a gimmick. It’s the result of collaboration between doctors, engineers, hardware designers, and clinical researchers.
We don’t just want you to see your health data.
We want that data to be accurate enough to trust, powerful enough to inform decisions, and meaningful enough to protect the ones you love.
Doni Ring: where smart meets science — and where technology truly cares.
