Wrist-Based SpO2, HR, and HRV Health Sensor Platform

This health sensor band platform is a wrist-worn wearable form factor that demonstrates the high sensitivity and algorithm processing functions for health-sensing applications. It includes an enclosure and a biometric sensor hub with an embedded algorithm for heart rate and SpO2 (blood oxygen saturation) which processes PPG (Photoplethysmography) signals from the analog-front-end (AFE) sensor. Algorithm output and raw data can be streamed through Bluetooth to an Android app or PC GUI for demonstration evaluation and customized development.Includes: Micro board MAX32630 microcontroller MAX20303 power-management IC (PMIC) Dual-mode Bluetooth® connection Tri-color status LED Sensor board MAX86141 analog front-end and optical heart rate sensor with one green LEDs one red LED one IR LED and two photodiodes MAX32664 microcontroller with embedded heart-rate algorithm Three-axis accelerometer MAX4740 quad SPDT switch which in combination with the MAX86140/41 enables different LED and PD configurations One green LED two combination RGB LEDs (One of these RGB LEDs is currently not used by the algorithm. The extra LED is reserved for future use: To simplify the design the extra LED and the MAX4740 may be removed for the heart rate SpO2 use case.) MAXDAP Pico Adapter board to be used during a firmware upgrade for the micro board Two USB Micro-B cables for firmware upgrade of the micro board or for PC communication with the micro board or charging of the health sensor band Health sensor band enclosure Battery One USB Type-C cable for PC communication with the micro board (Windows 7 or Windows 10) or charging of the health sensor band Additional requirements: PC (Windows 10 only) with Bluetooth connection for data streaming and logging Android device with Bluetooth connection for data streaming and logging
