Kardena® CARE Air 3 - The Future of Precise Wrist-Based Blood Pressure Monitoring

THE SECOND GENERATION OF PRESSURE-BASED BLOOD PRESSURE SMARTWATCHES FEATURING OSRAM SENSOR TECHNOLOGY FROM GERMANY!

 

At the beginning of 2025, Kardena® is once again setting new standards in digital health monitoring with the CARE Air 3. Building on the success of the Air series, this latest model integrates cutting-edge sensor technology to deliver even more accurate blood pressure measurements directly from the wrist. The official launch date is February 1, 2025.

What Makes the Air Series So Special?

The CARE Air series stands out with its innovative microairbag technology. A miniature air cushion integrated under the watch strap inflates in a controlled manner, enabling a pressure-based blood pressure measurement that mirrors the methodology of traditional upper-arm blood pressure monitors.

As a result, the CARE Air 3 offers significantly higher measurement accuracy compared to standard fitness trackers and smartwatches that rely on optical sensors. This state-of-the-art technology ensures reliable blood pressure readings and enables more precise health monitoring—perfect for those who prioritize their cardiovascular health.

What Makes the CARE Air 3 Unique?

The health smartwatch with German technology stands out with numerous technical and functional advancements, including:

  • New Health Sensors:
    • 8-channel heart rate sensor
    • 16-channel blood oxygen sensor
  • Bluetooth Calling with SOS Function: Stay connected and quickly request help in emergencies.
  • AMOLED Display: A crystal-clear 2.06-inch HD display ensures optimal readability and a premium look.
  • Rotating Crown: Provides an intuitive and comfortable navigation experience.
  • Microairbag Technology: Enables precise blood pressure measurements on the go, inspired by clinical-grade upper-arm blood pressure monitors.

The Innovation: EKG Nano-Conductive Glass Included

The CARE Air 3 takes health monitoring to a whole new level by combining cutting-edge technology with medical precision. One of its standout features is the nano-conductive EKG glass, specifically designed for accurate recording and interpretation of electrocardiograms (ECG/EKG).

Simple and Intelligent EKG Interpretation

Once your EKG data is recorded, the CARE Air 3 app analyzes it using an advanced AI algorithm that detects patterns of potential heart conditions. This technology scans your reports for irregularities and provides a clear and understandable interpretation, making it an invaluable tool for monitoring your heart health.

Why Is the EKG Glass So Important?

The CARE Air 3 allows you to detect potential heart problems early, before they develop into serious health concerns. By combining state-of-the-art sensor technology with intelligent data analysis, the smartwatch provides precise insights into your heart activity.

This feature is particularly valuable for preventive healthcare, helping you identify irregularities early and take necessary countermeasures before complications arise—whether by adjusting your lifestyle, consulting your doctor, or seeking further medical evaluation.

 

Advanced Sleep Monitoring with CARE Air 3 – Now with REM Sleep Analysis

The CARE Air 3 enhances sleep tracking by not only analyzing light and deep sleep phases but also monitoring your REM sleep, the stage crucial for memory formation and emotional processing.

Why Is REM Sleep Tracking Important?

  • Mental Health Improvement – REM sleep is vital for processing emotions and managing stress. Tracking it helps optimize mental balance.
  • Cognitive Performance – Supports learning, memory, and creativity. Insights from the CARE Air 3 allow you to refine your sleep routine for better brain recovery.

German Precision – Powered by OSRAM Sensor Technology

The CARE Air 3 features cutting-edge German-engineered OSRAM sensors, delivering unmatched accuracy in health tracking. The SFH2703 sensor, developed in Regensburg, Germany, enhances blood oxygen and circulation analysis.

Unlike standard smartwatches that rely on single-wavelength light, the CARE Air 3 uses three infrared wavelengths (680 nm, 750 nm, 910 nm) to precisely measure blood flow up to 4mm deep, ensuring more reliable health data.

With continuous oxygen saturation and respiratory rate tracking, real-time health trends can be viewed directly on the watch—helping you stay proactive about your well-being.


State-of-the-Art EKG Technology – Advanced Heart Health Monitoring with CARE Air 3

The CARE Air 3 sets a new standard in heart health monitoring, featuring the GH3220T EKG sensor from Goodix, a global leader in high-precision and energy-efficient sensor technology.

What Makes This EKG Sensor Revolutionary?

  • High Precision at Your Wrist – Combines single-lead EKG, heart rate monitoring, and SpO₂ measurement for detailed heart health insights. The 24-bit ADC (Analog-to-Digital Converter) detects even the smallest irregularities in your heart rhythm.
  • Heart Rate Variability (HRV) & Pulse Wave Transit Time (PWTT) – Tracks stress levels, circulatory function, and vascular health, essential for preventive care.
  • Accurate Temperature MonitoringDual NTC temperature sensors measure skin and body temperature in real time, helping detect fluctuations in your overall well-being.
  • Ultra-Low Power Consumption – The EKG mode consumes only 590 µA, ensuring an extended battery life of up to 7 days.

AI-Powered Health Analysis

Your EKG data is analyzed in the CARE Air 3 app using an AI-driven pattern recognition algorithm. This helps identify potential irregularities and provides clear insights, making it an invaluable tool for early detection of heart issues and proactive health management.
