# Circular’s Smart Ring 2: Non-Invasive Blood Pressure and Glucose Monitoring on the Horizon
## Introduction
Wearable health technology is rapidly evolving, and Circular is making an ambitious leap forward with its newest advancement. The company has revealed plans to roll out non-invasive **Blood Pressure and Blood Glucose monitoring** features for its **Ring 2** smart ring. Set to debut in **2025 and 2026**, these enhancements aim to grant users **greater insights into their health** without relying on traditional invasive techniques.
## What You Need to Know
– **Circular’s Ring 2** will be equipped with **Blood Pressure and Blood Glucose monitoring** capabilities.
– The **Blood Pressure feature** will utilize **ECG and PPG technology** for heightened accuracy.
– **Glucose monitoring** will assess blood sugar levels **without the need for needles or CGMs** (Continuous Glucose Monitors).
– If successful, Circular will be the **first company** to introduce non-invasive glucose monitoring in a smart ring, surpassing rivals like **Samsung**.
## Blood Pressure Monitoring: A Step Towards Accuracy
Circular aims to launch **Blood Pressure monitoring** on the Ring 2 through an **OTA (over-the-air) update** in **late 2025**. Unlike conventional blood pressure cuffs, the Ring 2 will leverage a combination of **ECG (Electrocardiogram) and PPG (Photoplethysmography) technologies**.
This integration is anticipated to yield **more precise readings** by measuring **Pulse Transit Time (PTT)**—the duration it takes for blood to flow through the arteries. According to Circular, users will be able to conduct **rapid assessments** in just **30 seconds to two minutes**, offering a **user-friendly and non-invasive** approach to blood pressure monitoring.
If successful, the **Ring 2 will be the first smart ring to achieve this advancement**, establishing a new standard in wearable health technology.
## Blood Glucose Monitoring: A Game-Changer for Diabetics?
The **second significant update**, expected in **late 2026**, will bring **Blood Glucose monitoring** on board. This feature could be **revolutionary**, enabling users to monitor their blood sugar levels **without finger-pricks or CGMs**.
The Ring 2 will employ **PPG sensors** and **machine-learning algorithms** to explore light interaction with blood. This information will assist in identifying **glucose fluctuations** and providing users with **long-term glucose patterns**.
While Circular acknowledges that this technology **won’t substitute traditional glucose monitoring methods**, it is confident that the feature will still offer **valuable insights** into blood sugar trends.
## How Circular Compares to Samsung
Circular’s announcement places it ahead of **Samsung**, which has been developing **non-invasive glucose monitoring** for its **Galaxy Watch**. Samsung’s **Hon Pak**, Senior Vice President of Digital Health, has referred to the feature as a **”game-changer”**, while highlighting the necessity of **accuracy** prior to its release.
Should Circular succeed, it may **outpace Samsung in the market** with a **wearable glucose monitoring solution**, positioning the Ring 2 as a **trailblazer in non-invasive health tracking**.
## The Future of Wearable Health Tech
Circular’s ambitious initiatives underscore the **increasing potential of smart rings** within the health tech landscape. If the **Ring 2’s blood pressure and glucose monitoring** are found to be **accurate and dependable**, it could transform **how individuals monitor their health**—particularly for those managing **hypertension or diabetes**.
While **concerns linger** about the **accuracy and reliability** of these features, Circular’s innovation indicates a **significant shift** towards **non-invasive health monitoring**. If successful, the **Ring 2 could redefine** the criteria for wearable health gadgets.
## Conclusion
Circular’s **Ring 2** is poised to emerge as a **robust health-tracking device**, with **non-invasive blood pressure and glucose monitoring** on the horizon. While the actual accuracy of these features is yet to be determined, the prospective influence on **healthcare and personal wellness** is **undeniable**.
With **updates anticipated in 2025 and 2026**, the global audience will be observing closely to see if Circular can **fulfill its commitments**—and potentially **outperform major competitors like Samsung** in the pursuit of **non-invasive health monitoring technology**.
