How Can Wearable ECG Patch Sensors Improve Early Detection of Atrial Fibrillation?

Breakthrough Wearable ECG Sensor Technology Delivers Continuous 24/7 Dynamic Holter Monitoring for High-Risk Patients

Atrial fibrillation (AFib) is one of the most common and dangerous cardiac arrhythmias worldwide, serving as a primary cause of stroke and heart failure. However, traditional clinical diagnostic methods often fail to capture paroxysmal or asymptomatic arrhythmias because standard tests rely heavily on brief 10-second resting ECGs in hospitals or bulky monitoring equipment. To resolve this diagnostic challenge, we have launched a new generation of wearable ECG patch devices, providing a lightweight and cost-effective dynamic ECG electrode solution for remote patient monitoring and clinical diagnosis.

Overcoming Diagnostic Challenges with Advanced Wearable ECG Sensor Technology

As one of the world's lightest mass-produced ECG monitoring devices (weighing just 8g to 14g), this innovative wearable ECG sensor redefines long-term cardiac care. Ergonomically designed for maximum patient comfort, subject users can wear it seamlessly during daily walking, home activities, and sleep, achieving 24/7 continuous high-precision medical-grade ECG and heart rate data collection.

Equipped with a high-sensitivity 3-axis accelerometer, the device seamlessly supports both online real-time transmission and offline continuous recording scenarios, outputting comprehensive multi-dimensional physiological metrics:

• Raw ECG Waveforms and R-R Interval (RRI)
• Heart Rate (HR) and Respiratory Rate (RR)
• Continuous Skin Temperature (TEMP)
• 3-Axis Acceleration (ACC) for posture detection, motion status analysis, and accurate step counting

Extended Battery Life and Intelligent Cloud Analytics

Under clinical guidance, subjects need to wear this rechargeable ECG patch for approximately one week per month to maintain long-term risk monitoring. Powered by an ultra-low-power architecture, the system supports 14 days of continuous Bluetooth wireless monitoring and up to 30 days of battery life in Holter mode, backed by 30 days of onboard local data storage to prevent data loss offline.

Biometric data collected via the disposable ECG electrode patch is automatically synchronized and uploaded to a secure cloud platform via a mobile application. Intelligent cloud algorithms analyze multi-parameter trends—such as heart rate variability, skin temperature fluctuations, and movement-correlated arrhythmias—helping physicians identify high-risk AFib patients long before noticeable symptoms appear.
