Wireless ECG: SpO2: PTT and heart rate monitor reference design for medical and consumer wearables
Texas Instruments
This reference design is a simple: wearable: multi-parameter: patient monitor that uses a single-chip: biosensing front end: AFE4900: for synchronized electrocardiography (ECG) and photoplethysmography (PPG) measurements. The measured data is transferred to a remote location using CC2640R2F (supporting BLE 4.2 and 5). The reference design is operated using a single CR3032 battery and provides a battery life of 30 days. The raw data is available for the user to calculate heart-rate: oxygen concentration in blood (SpO2): pulse-transit time (PTT): and ECG. Two onboard light-emitting diodes (LEDs) indicate low-battery detection and ECG lead-off detection for users.
Features
- Simple: wearable: multi-parameter: patient monitor for PPG and ECGProvides raw data to calculate heart rate: SpO2: and PTTUses single-chip: biosensing front-end AFE4900 for synchronized ECG and PPG measurementsPPG (Optical heart-rate monitoring and SpO2) supports four LEDs and three photodiodes (PDs): with digital ambient subtraction to improve signal-to-noise ratio (SNR)ECG (LEAD I) signalsIntegrated Arm® Cortex®-M3 and 2.4-GHz RF transceiver (CC2640R2F) supports wireless data transfer - BLE 4.2 and 5.0Operated by CR3032 (3-V: 500-mA coin-cell battery): with battery life of 30 days using highly efficient DC/DC convertersSmall form factor helps with easy adaptation to wearable applications
