Abstract

An Electrocardiogram (ECG or EKG) is an important feature in the medical environment, for instance in a hospital. Since this equipment is critical to the physician looking after the patient, the price of an ECG machine is high. When dealing with healthcare, one important aspect is the safety for both, the physician and the patient. The goal of this project is to produce a substitute, which is a cheaper version of the ECG circuit. Also treating the ECG as an Electromyography (EMG), experiment would be done to verify if the former could serve as a dual purpose circuit.

Operational amplifiers (op-amps) are very useful in electronics and is the reason why they are present in almost all the major industries such as automotive and medical. This project will explore some of the qualities that op-amps can offer to meet the demand of this project. In addition, a safety circuit will be executed to ensure that the safety of the device as well as the operator is respected in all aspects. Murdoch University has an EKG sensor from Vernier, which can be used to demonstrate whether the results achieved through the amplifiers circuit’s, matches the readings from Vernier’s sensor.

Finally modelling is magic as it opens the creativity mind of people, allowing them to think freely. Using this boon some modelling of muscle types have been done as it is really hard to take the EMG of two muscle types.
