A family of sensor hub products with optimised vital sensing features has been introduced by Bosch Sensortech at Mobile World Congress in Barcelona (Feb 22-25). These devices fuse photoplethysmography (PPG) signals with the onboard inertial MEMS sensors signals for robust, motion compensated heart rate measurement and provide users with valuable insights about their wellbeing and fitness level using Firstbeat’s field-proven vital analytics algorithms.
The BHV250 and BHV160 sensors are designed for always-on sensor enabled wearable applications such as fitness wristbands, earphones and smart textiles. As a complete sensor solution they feature ultra-low power consumption in a compact package, with integrated software and a wide-range support for different PPG chipsets.
The integrated software from Firstbeat processes raw sensor data to open up a world of motion-compensated vital monitoring, activity recognition applications and gesture based user interfaces.
The combination of the Bosch’s Vital Sensor Hubs with Firstbeat’s extensive vital analytics software enables a rich user experience by providing the tools for sleep analysis, calorie consumption calculation, fitness training evaluation, and "stress and recovery" monitoring. The myriad of future applications is only limited by the designer's imagination.
The BHV250 and BHV160 integrate innovative 3- respectively 6-axis inertial MEMS sensors designed around the new Bosch Sensortec DSP ‘Fuser Core’ powering Firstbeat’s vital analytics software. Both devices include an accelerometer, and the BHV160 also includes a gyroscope.
The Androi Wear-compatible sensor hubs are the components with the lowest power consumption available on the market today, helping to significantly extend system battery life time.
The sensor hubs have tiny footprints that are indispensable for applications where space is tight. The BHV160 measures 3 x 3 x 0.95 mm3, while the BHV250 only a mere 2.2 x 2.2 x 0.95 mm3.
