Level: Masters

Semester: 1

Assessment: EX50PR50

Requisites:

Aims & Learning Objectives:
The primary aim is to familiarise students with some of the important medical applications of electronics, where there is direct connection to the body, and to explain how the requirements for the equipment are derived.
After taking this unit the student should be able to:
* Have an overview of the subject of Medical Electronics and its relevance to Engineers and Medical professionals
* Have a knowledge on physiological signal evolution and characteristics
* Have a knowledge and understanding of electrodes.
* Have a knowledge and understanding of electrical stimulation.
* Understand electric shock hazards and safety devices.
* Understanding of the characteristics and limitations of biomedical amplifiers for acquisition of electrophysiological signals, how these characteristics are derived from an understanding of electrophysiology,
* Apply knowledge of stimulators and biomedical amplifiers during laboratory practicals.
