TIDA-01580
Wireless ECG, SpO2, PTT and heart rate monitor reference design for medical and consumer wearables
TIDA-01580
Overview
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 ECG
- Provides raw data to calculate heart rate, SpO2, and PTT
- Uses single-chip, biosensing front-end AFE4900 for synchronized ECG and PPG measurements
- PPG (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) signals
- Integrated Arm® Cortex®-M3 and 2.4-GHz RF transceiver (CC2640R2F) supports wireless data transfer - BLE 4.2 and 5.0
- Operated by CR3032 (3-V, 500-mA coin-cell battery), with battery life of 30 days using highly efficient DC/DC converters
- Small form factor helps with easy adaptation to wearable applications
