ECG Design
Computational Fundamentals of BME Design
Overview
Objective
Design an ECG device with a PCB, housing unit, and user interface that can visualize heart rate
Process
Created an ECG circuit with an instrumentation amplifier, virtual ground, high pass filter, and low pass filter with Fusion 360
Evaluated the performance of the circuit with a dynamic signal analyzer and bode analyzer
Designed a CAD model of a case that would contain the ECG circuit as a PCB, 9V batteries, and ports for electrodes
Implemented an online user interface that will output the electrode signals using LabView
Result
Through online testing, the circuit was able to filter and amplify the ECG signal
Heart rate was successfully visualized with the online user interface which included a power button, a pause button, a beats-per-minute counter
