ECG Measurement System

Faculty Mentor: Dr. Jack Ou, Department of Engineering Science

An ECG is a test that records the electrical activity of the heart. It can be used to measure the rate and regularity of heartbeats. We will build an ECG measurement system consisted of an AgCl electrode, an instrumentation amplifier, an opto-coupler, and a bandpass filter. The AgCl electrode will convert an ECG signal into electrical voltage. The instrumentation amplifier will amplify the heartbeat and reject the noise from the surroundings. The opto-coupler will be used to isolate the amplifier from the measurement equipment. A bandpass filter will be used to remove high frequency noise. High school students interested in a career in Medicine, Biomedical Engineering, or Electrical Engineering may be interested in this project.
