配备 Bluetooth® 5 的可穿戴 16 相多传感器 SpO2 和心率监测仪 (HRM) 参考设计
TIDA-010029
概述
This reference design enables a wearable, optimized saturation of peripheral capillary oxygen (SpO2) and multi-sensor, multi-wavelength optical heart rate monitor (HRM). It uses AFE4420 device, which is a single-chip, bio-sensing front end for photoplethysmography (PPG) measurements. It supports up to four switching light-emitting diodes (LEDs) and up to four photodiodes to enable signal acquisition of up to 16 Phases. The CC2640R2F device (supporting Bluetooth® low energy 4.2 and 5) transfers the measured data to a remote location. This patient-monitoring design uses a single CR3032 battery with a 30-day life cycle. Raw data is available to calculate heart rate, SpO2, and other related parameters. 2 onboard light-emitting diodes (LEDs) identify low-battery detection and a Bluetooth connection.
特性
- Provides raw data to calculate heart rate, SpO2, and other related parameters
- Uses single-chip, bio-sensing, front-end AFE4420 device for PPG measurement
- Supports up to 4 LEDs and 4 photodiodes with ambient subtraction to improve signal-to-noise ratio (SNR)
- Enables signal acquisition of up to 16 phases and multi-wavelength measurements with the flexible allocation of LEDs and photodiodes in each phase
- Integrated Arm® Cortex®-M3 and 2.4-GHz RF transceiver (CC2640R2F) supports wireless data transfer through Bluetooth® low energy 4.2 and 5.0
- Operates from CR3032 (3-V, 500-mA coin cell battery) with a battery life of 30 days using highly efficient DC/DC converters
- Small form factor helps in easy adaption to wearable applications
