ELEC1212 Biomedical Engineering Design

Module Overview

This is a new design module that utilises existing lecture material, but places the emphasis on demonstrating understanding by designing systems using the knowledge gained from the lectures. The module split in two; 50% control and 50% biomedical signals analysis. The control topics include electrical/mech analogues, p notation, block diagrams, electromech systems: torque, inertia, motor model, along with a new design exercise; Design of an Active Tremor Suppression Brace for Parkinsons. The biomedical signals analysis part will give a theoretical understanding of the fundamentals of biomedical signal processing. Students will then demonstrate practical use of this understanding by designing an automated algorithm for ECG analysis. This module will also include the engineering design process and principles.
