Biosensors add ECG measurement to wearables

December 13, 2017  Stephen Law

SILICON LAB Si117x family of optical biometric sensors deliver high heart rate monitoring (HRM) accuracy while minimizing power consumption for all-day monitoring. Devices deliver electrocardiogram (ECG) capabilities for a wide range of wearable fitness and wellness products. Devices combine ultra-low power, high sensitivity and exceptional integration. Sensors consume less than 50µA (sensor and LED combined) while performing continuous HRM. A built-in buffer and accelerometer synchronization capabilities save even more system-level power. Devices provide fast sampling speeds, a high signal-to-noise ratio (SNR >100dB), and the ability to cancel out ambient noise and erroneous data.
