Beijing, China - December 20, 2017 - Silicon Labs (NASDAQ: SLAB) today introduced a series of optical biometric sensors that provide advanced heart rate monitoring for a variety of wearable fitness and wellness products HRM and ECG capabilities The new Si117x sensor module offers ultra-low power consumption, high sensitivity and excellent integration ideal for smartwatches, wrists, patch devices that require long battery life and higher heart rate accuracy Or other wearable devices. To simplify development and reduce time-to-market, Silicon Labs offers a complete sensing solution that integrates the Si117x sensor module, heart rate algorithm, Wireless Gecko SoC with Bluetooth® connectivity, and includes sample code, sample projects And easy-to-use wrist development kit Silicon Labs will be simultaneously exhibiting the Si117x sensor module and a complete solution at the 6th Shenzhen Embedded Expo hosted December 21-23 Visit booth 1A08 of Hall 1 of Shenzhen Convention & Exhibition Center.
Heart rate monitoring around the clock is a key requirement for health and fitness wearable devices By tracking heart rate throughout the day, end-users and healthcare providers can analyze physiological data to detect health conditions and consider lifestyle adjustments before health problems are discovered. Power requirements, the Si117x sensor consumes less than 50μA of current (sensor and LED total) for continuous heartbeat measurements. The built-in buffer and accelerometer synchronization saves more system-level power consumption. With sensor-class industry-leading power consumption Control technology, developers can use smaller batteries in wearable designs without significantly affecting the battery life of the device during continuous monitoring.
The Si117x sensors provide enhanced end-user experience with enhanced heart rate measurement accuracy, providing fast sampling, high S / N (SNR> 100dB), and the ability to eliminate ambient noise and false data filtering, despite the different Physiological characteristics, skin tone, and tattoos can still produce high-quality signals that make it easier to track heart rate. A more accurate ECG waveform view allows biometrics to move beyond traditional heart rate monitoring, including heart rate variability (HRV), stress analysis And pulse volume.
By combining ECG measurements with optical heartbeat measurements, the Si117x sensor enables developers to open up new potential biometrics for wearable devices.The ECG waveform is the gold standard for heart condition measurement, and the Si117x sensor offers this feature in a cost-effective manner For wrist wearable devices By simultaneously measuring on the same device, the Si117x sensor allows developers to combine biometrics with optical photoplethysmography (PPG) measurements for more valuable physiological parameters.
The Si117x module's high level of integration simplifies the wearable design, making it easier to measure multiple sensors simultaneously without adding significant system cost or board area. Each module supports up to 4 different LEDs (all can be (From 1.7mA to 310mA). Other built-in features include photodetectors, 24-bit ADCs with> 100dB dynamic range, I2C and SPI digital interfaces, programmable event interrupt engine, synchronization Engine, host communications processor and two external photodiode inputs.
Tom Pannell, senior director of marketing for IoT products at Silicon Labs, said: "As the health and fitness wearables market continues to grow, developers need a complete biometric sensor solution that works seamlessly without complex integration." Silicon Labs is the only provider that alone can offer total heart rate monitoring system solutions, ranging from sensor modules and algorithms to wireless SoCs that transmit measurements through Bluetooth LE Our Heart Rhythm Monitor example project considers the relationship between these components Interface, to provide a simple communication interface between modules to simplify customer support and debugging.
The Si117x sensor supports Silicon Labs' proprietary motion compensation arrhythmia algorithms optimized for wrist measurements and runs on EFM32 Gecko MCUs and EFR32 Wireless Gecko SoCs that support Bluetooth Low Energy. This integration enables system-level Power and performance optimization, and reduce the developer's time to add heart rate monitoring capabilities to their wearable designs.
At the upcoming Shenzhen International Embedded Systems Expo to be held in Shenzhen Convention & Exhibition Center, Silicon Labs will be showcasing the Si117x sensor module along with a complete set of cardiac rhythm algorithms and Wireless Gecko SoC solutions, as well as demonstrations of intelligent embedded Bluetooth and zigbee wireless protocols, sensing, MCUs and isolation schemes and products required for the system. Silicon Labs' technical experts will meet with developers face-to-face and help them become more connected to the world through live product demonstrations. Welcome to Silicon Labs Shenzhen Exhibition Hall 1A08 booth number.
