Wireless ECG Hardware

Project Overview

The purpose of this wireless ECG device is to transmit data about a person's heart rate in real time, using a non-intrusive, low power, band-aid sized probes to a smartphone. The smartphone will receive the output from the ECG via Bluetooth and either store it for later analysis or upload it for analysis in real time. The smartphone will also be able to detect when the output indicates a medical emergency, such as cardiac arrest, and call an ambulance on behalf of the patient. The idea behind our project was to improve upon an existing wireless ECG design. The sensors used in the current design were not performing to meet our expectations and would require the patient to remain still in order to receive a useable signal. Our group also invested time in improving on the filtering performed to the ECG signal data that is received from the sensors and describing the reason for choosing our Bluetooth transmitter.
