ECE students create a safe and quick way to measure heart rate

A device created by ECE students Sean Hubber and Crystal Lu, Hands-On Electrocardiography, was published in the August 2014 issue of Circuit Cellar Magazine (#289, pp 36-42). Developed in ECE5030, their project provides a safe, simple, and inexpensive method of measuring someone’s heart rate from just dry metal hand grips. After researching ideas for heart rate systems such as those incorporated into treadmills, the two built a  instrumentation circuit and used Matlab on a PC for display and analysis. As a subsequent independent study, the project was converted from Matlab to Arduino microcontroller and packaged for portability.  In addition to the challenging technical content,  the project exposed the students to ethical concerns about privacy of health data and designing for safety.
