Silicon Labs (also known as "core technology") has released a new set of optical biosensors, the Si117x, which provides advanced heart rate monitoring (HRM) and electrocardiogram (ECG) capabilities for a variety of wearable health and fitness applications. Health care equipment. Click on “Read the original†to explore more details on the sensor modules for Silicon Labs Si117x heart rate monitoring plus ECG measurement.
Si117x set ultra-low power consumption, high sensitivity, high integration in one
The new Si117x sensor module combines ultra-low power consumption, high sensitivity and unique integration capabilities, making them ideal for smart watches and other wearable devices based on watch lines that require long battery life. And stronger biological information sensing and management capabilities. To help engineers simplify development complexity and speed time-to-market, SiliconLabs offers a complete end-to-end sensing solution that includes Si117x sensor modules, HRM algorithms, and Bluetooth connectivity based on Wireless Gecko multi-protocol wireless SoCs. , plus an easy-to-use code-based development kit, sample code and sample projects.
A key requirement for health and fitness wearables is to save power. By tracking the entire day's personal physiological information, end users and healthcare providers can be provided with data to analyze physiological patterns, and to identify and consider lifestyle adjustments as early as possible before the user's body becomes a problem. To meet the market's need for power efficiency, the Si117x sensor consumes less than 50 μA (including sensors and LEDs) when performing continuous biometric data acquisition and management. Built-in buffer and accelerometer synchronization saves more system-level power. This industry-leading energy-saving advantage allows developers to use smaller batteries in wearable designs without significantly affecting the battery life of the device during continuous monitoring.
The Si117x sensor provides enhanced human resource management for a better end-user experience. The sensor provides fast sampling speed, high signal-to-noise ratio (SNR>100dB), and the ability to eliminate ambient noise and erroneous data, resulting in high quality signals despite challenging physiological features, different skin tones and tattoos. Exist, it's easier to track heart rate. A more precise view of human resource waveforms can enable biometrics to go beyond traditional human resource management, including heart rate changes (HRV), stress analysis, and pulse volume. 
Combine ECG measurements to obtain more valuable physiological parameters
By combining ECG measurement data with heart rate monitoring, the Si117x sensor allows developers to unlock new biometrics for wearable devices. The ECG waveform is the gold standard for cardiac measurements, while the Si117x sensor brings this capability to wearable devices based on watch styles in a cost-effective and efficient manner. By measuring on the same device, the Si117x sensor allows developers to combine biometrics with PPG measurements to obtain more valuable physiological parameters.
