PROJECT CONCEPT

The goal of this project is to build a wearable ECG monitor that fits comfortably into daily living. The system integrates electrodes and an embedded microcontroller into a shirt and sends cardiac signal data over bluetooth to a smartphone or PDA where it is processed in real-time to detect cardiac events and issue warnings to the user.

MOTIVATION

Existing ECG monitoring solutions are not suitable for sustained wear during daily activities due to uncomfortable electrodes and cumbersome wires, short battery life, bulky design, and the requirement that data must be taken to a doctor's office for processing. Our wearable ECG device will enable cardiac patients of all types to easily monitor their heart for irregularities or warning signs, store and send cardiac data to their physician, and detect problems early for better health.

Testing at the Robotics Club

Thanks to the kindness of the other groups in the lab ... I did not recieve many complaints about my exposed smelly feet.
