TIDA-01580
This reference design is a simple, wearable, multi-parameter, patient monitor that uses a single-chip, biosensing front end, the AFE4900 device, for synchronized electrocardiography (ECG) and photoplethysmography (PPG) measurements. The measured data is transferred to a remote location using the CC2640R2F device (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.
