Circul Ring Measures Blood Pressure

Technology Overview

You experience a new era of blood pressure monitoring with Circul Ring. This device uses a combination of advanced hardware and intelligent software to give you accurate, real-time health data. The system includes the ring itself, a smart cradle, and a cloud-based network for data processing. You do not need to worry about bulky cuffs or complicated setups. The ring fits comfortably on your finger and adapts to different finger sizes, ensuring consistent sensor contact.

Circul Ring Measures Blood Pressure by capturing your blood flow signals through its high-frequency sensors. The device uses ultrasound sensing technology and intelligent algorithms to collect blood pressure waveform data. This approach allows you to track rapid changes in your blood pressure that traditional devices might miss. Trials in hospitals have shown that this non-invasive method delivers accuracy close to invasive techniques. You can trust the readings for both daily health checks and long-term monitoring.

Tip: You can wear the Circul Ring throughout the day. It allows you to take non-invasive blood pressure readings anytime, helping you easily observe how your blood pressure changes during different activities or times of the day.

World’s First: Lab-Grade Wearable

You need a device you can truly trust. Circul Ring’s blood pressure monitoring is designed with lab-grade accuracy in mind. Its system leverages advanced AI models trained on over 100,000 real-world medical records, including blood pressure and PPG data across diverse populations. Before its official release, Circul Ring underwent thousands of real-user tests. Hospitals and clinics compared its readings against the gold-standard invasive blood pressure measurements—and the results showed remarkable alignment.

Note: Many users worry that home blood pressure monitors give random or inconsistent results. Circul Ring’s lab-grade validation is designed to eliminate that concern.

AI-Powered Precision at Your Fingertips

Precision ultimately depends on technical depth. Circul Ring builds a dual moat of hardware and algorithm innovation:

With 125 Hz high-frequency PPG sampling and an LSTM-AT attention-based AI model, Circul Ring performs cloud-based inference in seconds. It extracts deeper vascular signals—including SPV, SVV, PPV, VPV, ΔVpeak, ΔABF—for leading-edge accuracy and responsiveness.

Pro Tip: You can wear Circul Ring all day for non-invasive blood pressure checks anytime. Easily track how your blood pressure fluctuates across different activities and time periods.

Measurement Process

You can measure your blood pressure with Circul Ring in a few simple steps. The process is designed to be intuitive and user-friendly, making it easy for anyone to get accurate results. Here’s how you do it:

• Update the CIRCUL App and firmware to the latest version.

• Open the CIRCUL App on your phone.

The days of stressful waits are over. Powered by Circul Ring’s proprietary cloud inference engine, blood pressure readings are delivered within seconds—that’s up to 80% faster than traditional cuff-based devices and 50% faster than most other wearables.

Speed doesn’t come at the cost of accuracy. With the dual power of high-frequency sampling and AI-driven algorithms, Circul Ring delivers fast and precise results in one seamless experience. Whether you’re rushing out the door in the morning or curious about your body’s response after a workout, you get instant insights—on demand.

Pro Tip: For best accuracy, try sitting still for a few minutes before taking a measurement.

Accuracy and Reliability

Factors Influencing Results

When using wearable devices for blood pressure monitoring, many users are concerned about the accuracy of the readings. In fact, blood pressure measurements can be influenced by various factors. Understanding these factors can help you use the device more effectively and obtain more reliable data. Circul Ring is carefully designed to address common challenges, ensuring stable and precise measurement results.

• First, the placement of the ring is crucial. Circul Ring is designed to be worn near the digital artery in your finger, allowing it to capture high-quality blood flow signals directly, which improves signal clarity and accuracy.
• Second, stable skin contact is essential for smooth measurement. Maintaining good contact between your finger and the ring minimizes interference signals caused by hand movement.
• Additionally, keeping your finger as still as possible during measurement significantly enhances data accuracy. Although some environmental factors may affect the measurement, the Circul Ring’s structural design and advanced signal processing technology effectively filter out most external interferences, ensuring reliable readings.

With these multiple technical advantages combined, Circul Ring becomes a trusted partner in your daily health management, helping you easily understand your physical condition and make smarter health decisions.
