TIDA-01580 Reference Design

Texas Instruments

Wearable, Wireless, Multi-Parameter Patient Monitor Reference Design


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.

  • 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 device 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); and 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
  • Pulse Oximeter
  • Electrocardiogram (ECG)
  • Fitness Machines
  • Wearable Fitness & Activity Monitor
  • Wireless Patient Monitor
  • Clinical Digital Thermometer
  • Digital Stethoscope
