Design files

Overview

The Edge-artificial intelligence (AI) ready wearable biosensing Holter reference design provides an evaluation platform for our latest offerings in continuous monitoring of vital signs such as electrocardiography (ECG), heart rate, respiration, pace pulse, temperature and motion. The design uses the AFE159RP4 for low-power, high-resolution, and highly-integrated ECG signal acquisition with up to six leads (four channels) and the TMP119 for body temperature monitoring. The measured data is processed by the MSPM0 MCU with hardware acceleration for real-time arrhythmia classification, then transferred by the CC2340R5 (with Bluetooth® Low Energy (LE) 5.3 support) to a remote terminal such as a smartphone or medical monitoring system for real-time display. The full system can be powered by 2 × CR2032 batteries (3V input) or 1 × AAA battery (1.5V input).

Features
  • On-device AI hardware accelerator delivers immediate and precise detection of cardiac events
  • Advanced low-power features along with high resolution recording and transmission only when necessary, enabling extended wear times
  • Small, multiparameter single-chip ECG Holter monitor design for synchronized ECG, respiration and pace pulse detection
  • Ultra-low-power 2.4G Bluetooth LE 5.3, Arm® Cortex®-M0+ processor supports wireless data transfer
  • Highly efficient DC/DC converters support both 2 × CR2032 (3V, 210mAh) coin-cell batteries and 1 × AAA battery (1.5V, 500mAh)
  • SimpleLink™ Connect mobile application for real-time ECG, arrhythmia classification, respiration, pace pulse and temperature display
