The Aktiia Bracelet is a groundbreaking wearable device designed to continuously monitor blood pressure without the need for traditional cuffs. Developed by Swiss health-tech company Aktiia SA, the bracelet combines optical sensor technology with advanced algorithms to provide 24/7 blood pressure readings, making it one of the most innovative solutions in cardiovascular health monitoring.
In a world increasingly concerned with heart health, the Aktiia Bracelet addresses a critical gap in how blood pressure is traditionally measured. It empowers users with accurate, consistent, and user-friendly data to support long-term cardiovascular well-being.
The Evolution of Blood Pressure Monitoring
Traditional Cuff-Based Devices
For decades, blood pressure monitoring has relied on oscillometric cuff-based devices. These are accurate but cumbersome for frequent use. Measuring blood pressure multiple times a day becomes inconvenient, especially for elderly users or those with mobility challenges.
The Shift to Wearables
Wearables have transformed personal health monitoring. Devices like fitness trackers and smartwatches now monitor heart rate, sleep, and activity. However, continuous and accurate blood pressure tracking has remained elusive—until the arrival of the Aktiia Bracelet.
Who Developed the Aktiia Bracelet?
Company Overview
Aktiia SA was founded in 2018 as a spin-off from the Swiss Center for Electronics and Microtechnology (CSEM). The company leverages over 15 years of research and clinical trials focused on optical blood pressure measurement.
Founders and Mission
The company was co-founded by Dr. Mattia Bertschi and Dr. Josep Sola. Their mission was clear: make blood pressure monitoring more accessible, less intrusive, and more meaningful through long-term data.
What Makes the Aktiia Bracelet Unique?
Continuous, Cuffless Monitoring
Unlike traditional monitors that provide single-point measurements, the Aktiia Bracelet offers continuous blood pressure readings throughout the day and night. This gives users a comprehensive view of their cardiovascular trends.
Optical Sensor Technology
The bracelet uses photoplethysmography (PPG) sensors to measure blood volume changes in the arteries. These are the same types of sensors used in smartwatches to detect heart rate but are refined for medical-grade accuracy.
Proprietary Algorithms
Aktiia combines its PPG sensors with proprietary algorithms that interpret the optical signals to produce blood pressure values. The algorithms have been validated in clinical settings to ensure accuracy.
How the Aktiia Bracelet Works
Initial Calibration
To start using the bracelet, users must calibrate it with a traditional blood pressure cuff provided in the starter kit. This calibration is done once every month to maintain accuracy.
Day and Night Monitoring
Once calibrated, the bracelet automatically measures blood pressure every hour. This includes nocturnal readings, which are critical for understanding hypertension patterns.
Data Synchronization
The bracelet syncs with the Aktiia app via Bluetooth. Users can view daily, weekly, and monthly blood pressure trends, helping them and their doctors make informed decisions.
Design and Comfort
Discreet Aesthetic
The Aktiia Bracelet is sleek, minimalistic, and designed to look like a fashion accessory rather than a medical device. It does not display data on the bracelet itself, preserving a low-profile look.
Lightweight and Durable
Weighing just a few grams, the bracelet is comfortable for all-day wear. It is water-resistant, suitable for everyday activities, and built with materials that minimize skin irritation.
Features of the Aktiia Bracelet
24/7 Blood Pressure Monitoring
The primary feature is its ability to deliver accurate, continuous blood pressure readings. This includes systolic and diastolic values, measured automatically without user intervention.
Mobile App Integration
The Aktiia app provides intuitive visualizations, including:
- Color-coded zones for hypertension stages
- Weekly and monthly trends
- Ability to share reports with healthcare providers
Battery Life
The device boasts an impressive battery life of up to 9 days on a single charge. This makes it far more efficient than most health wearables, which often require daily charging.
Cloud Data Storage
All measurements are securely stored in the cloud, ensuring that users have access to their health history even if they switch devices.
Medical Accuracy and Clinical Validation
CE Certification
The Aktiia Bracelet is CE-marked as a Class IIa medical device in Europe, confirming its compliance with health and safety standards. However, it is not yet FDA-approved in the U.S.
Clinical Trials
Aktiia has published multiple peer-reviewed studies validating the accuracy of its measurements. These studies demonstrate performance comparable to traditional ambulatory blood pressure monitors (ABPM).
Limitations and Exclusions
The device may not be suitable for individuals with arrhythmias, peripheral vascular diseases, or other specific medical conditions that affect optical measurement accuracy.
Comparing Aktiia with Other Devices
| Feature | Aktiia Bracelet | Traditional Cuff | Smartwatches |
|---|---|---|---|
| Continuous BP Monitoring | ✅ | ❌ | ❌ |
| Cuffless | ✅ | ❌ | ✅ (but often inaccurate) |
| Medical Certification | ✅ | ✅ | ❌ |
| Comfort for Daily Wear | ✅ | ❌ | ✅ |
| Nighttime Monitoring | ✅ | ❌ | ❌ |
| Real-Time Display | ❌ | ✅ | ✅ |
The Aktiia Bracelet stands out in its ability to balance comfort, accuracy, and continuous data collection in one package.
Ideal Users of the Aktiia Bracelet
Hypertensive Patients
Patients with high blood pressure benefit from continuous tracking. Fluctuations in readings can reveal patterns not captured by occasional measurements.
Health-Conscious Individuals
Even people without diagnosed hypertension can use the device to monitor cardiovascular health over time, especially those with family history or lifestyle risk factors.
Elderly Users
The cuffless, automated nature of the bracelet is ideal for elderly patients who may find traditional monitors difficult to use.
How to Buy the Aktiia Bracelet

Limitations and Considerations
No Real-Time Display
The bracelet does not have a display. All information must be accessed through the app, which might be inconvenient for some users.
Not for Emergency Use
Aktiia is intended for long-term monitoring and is not a substitute for emergency blood pressure readings in clinical settings.
Monthly Calibration Required
Although minimal, the monthly calibration step requires user discipline and use of the provided cuff.
Customer Feedback and Testimonials
Users consistently report high satisfaction, citing:
- Ease of use
- Non-intrusive design
- Insightful data visualizations
Some users note the need for better compatibility with third-party health apps and suggest real-time alerts as a future improvement.
