Switzerland-based Aktiia offers a passive remote patient-monitoring solution consisting of a wearable blood pressure bracelet and a mobile app. The device uses optical sensors and algorithms to monitor blood pressure more than 12 times a day, including at night. Aktiia's bracelet estimates relative blood pressure changes by shining a green light on the wrist and analyzing the resulting photoplethysmographic (PPG) signals. To obtain absolute blood pressure readings in mmHg, users need to take readings once a month with a traditional blood pressure cuff.
The wearable device connects to Aktiia's app via Bluetooth, displaying blood pressure readings, including the 24-hour average, daily variations, and resting heart rate. The app also provides trends and insights into cardiovascular health and allows users to share digital reports with their clinicians.
The device was launched for commercial use, after receiving a CE mark as a Class ll a medical device in January 2021. As of May 2024, Aktiia's device has gained over 70,000 customers globally and had recieved medical approval in 44 countries. However, the company was still pursuing FDA approval in May 2024 and had plans to launch in the US in 2025. The cuff and bracelet are available to individuals in the UK for GBP 199.99; users will also be able to sign up for a monthly blood pressure monitoring service priced at GDP 8.99 after the first year.
