It is important for a medical device engineer to have an understanding of the foundations of biomedical instruments and to also make connections between biology, physiology, and electrical engineering. This course will introduce the basic principles and design issues of biomedical sensors and instrumentation that measure quantities related to living biological systems, as well as actuators that can be used to manipulate flows and temperatures. The physical principles of biomedical sensors, analysis of biomedical instrumentation systems, and application specific biomedical sensor and instrumentation design will be considered. Analogue circuits such as high-order active filters, biopotential amplifiers and ADC converters will be discussed in detail. The basic principles required to design and understand drive circuits for commonly used rotary and linear actuators will also be provided. A basic introduction to feedback control is provided to show how measurements can be used to provide regulation via an appropriate actuation. By the end of the course students will be able to analyse and design medical devices capable of measuring and/or interacting with the human body.

On successful completion of the course students will be able to:
1. Demonstrate knowledge of biomedical instrumentation and its application to physiological and cellular measurements.
2. Analyze and design analog circuits and systems for biomedical sensing.
3. Demonstrate knowledge of real world biomedical sensing problems (e.g. motion artifacts, skin-electrode interface, low signal to noise ratios) and apply strategies for their mitigation.
4. Design and select different actuators and drives for medical pumps, prosthetics and surgical devices.
5. Communicate the design of biomedical sensing systems to a diverse audience of engineers and / or clinicians via written and oral presentation.
