Curricular information is subject to change
On successful completion of this module the student will be able to:
- apply the principles of electrical circuit theory and analyses to the use and design of instrumentation in the biomedical area;
- explain the operating principles of biomedical transducers for themeasurement of biopotentials (ECG, EMG, EEG, EOG) and other critical physiological variables such as blood pressure, flow, and temperature;
- design and build analog signal conditioning circuits that provide reliable biopotential measurements, e.g. ECG;
- explain the physical principles underlying the function of biopotential electrodes;
- demonstrate knowledge of electrical safety considerations in the medicalenvironment;
- demonstrate programming skills through the use of MATLAB or Python for back-end data acquisition and elementary digital signal processing.
Below is a rough list of topics covered when the class was delivered in Spring 2021:
* Intro/outline
* Sensor static characteristics
* Sensor calibration
* Revision of electrical engineering (up to opamps and phasors)
* Passive conditioning circuits (RC filters, Bode plots)
* Active conditioning circuits (active (opamp) filters)
* Bioelectricity (membrane potentials, equilibrium (Nernst), voltage gated channels, action potentials, myelin, volume conduction)
* Electrophysiology (examples of EEG, ECG, EMG, EOG,...)
* Electodes (oxidation/reduction, electrolytes, electrode electrical models)
* Advanced conditioning circuits (noise, interference, shielding, active shielding, driven right leg active ground)
* Sensing displacement (strain gauges, LVDTs, piezocrystals, MEMS accelerometers and gyroscopes, optical sensors)
* Bridges (no bridge; 1/4, 1/2, full bridge)
* Electrical safety
* Revision

• Feedback individually to students, on an activity or draft prior to summative assessment
• Feedback individually to students, post-assessment
• Group/class feedback, post-assessment
Labs: Students can seek feedback when preparing laboratory reports from the demonstrators (during the lab session) or the module coordinator. Written post-assessment feedback if lab reports will be given on Brightspace when the lab mark is released; the extent of this feedback depends on the number of deficiencies found in the lab report. Midterm exam: During course revision, general feedback will be given on where most common errors occured in the midterm exam.
