Novosound, a Scottish company, is showcasing its groundbreaking ultrasound blood pressure monitoring device at CES 2025. The device, named Slanj, utilizes thin-film ultrasound technology and claims to achieve accuracy comparable to traditional cuff-based methods. This innovative wearable sensor promises real-time blood pressure monitoring without the need for cuffs or wires.
In the world of mass-market wrist-based wearables, blood pressure sensing is being seen as the next holy grail for health monitoring. Samsung has already rolled out blood pressure sensing on its smartwatches, with a calibration caveat. However, the approach taken by the likes of Samsung isn’t the most accurate out there.
The Galaxy Watch, for example, relies on a Photoplethysmogram (PPG) sensor that shines light through the vessels to measure the change in blood volume and accordingly provide a blood pressure estimate. At the dawn of 2025, we are on the cusp of another wearable blood pressure sensing breakthrough, one that is more accurate and comes courtesy of Novosound. The Scottish company is demonstrating its ultrasound blood pressure monitoring device at CES 2025.

The company claims that Slanj is a world’s-first wearable ultrasound sensor that can monitor blood pressure levels in real time without cuffs or wires. Notably, the sensor stack can also measure other body stats such as muscle health and hydration levels.

Novosound clearly states that the miniaturized ultrasonic blood pressure sensor is destined for smartwatches and even smart ring
