Circular unveils its next gen Ring 2 with ECG functionality and AFib detection at CES 2025 | TechCrunch
Briefly

With the Circular Ring 2, we've reimagined what a smart ring can be-combining advanced health technology with timeless design and unmatched durability. This isn't just a wearable; it's a statement piece that empowers our users to take control of their wellness without compromising on style.
The wearable can capture a single-lead ECG, which is a way of recording the electrical activity of your heart, using an advanced PPG sensor. PPG sensors work by shining light onto your skin to measure changes in blood flow.
The new ring comes with additional upgrades compared to its predecessor, including a better battery life; the company promises eight days. It also comes with enhanced sensors to track key health metrics, including sleep analysis.
Circular is also launching a Digital Ring Sizing feature that you can access on your smartphone before you place an order.
