Biopotential measurement notes

Ideas for level 9 biopotential measurement module:

Biopotentials are voltage signals measured between different points on (or in) an organism. Examples commonly recorded from the human body include electrocardiogram (ECG), electromyogram (EMG), and electroencephalogram (EEG). This module introduces learners to the fundamental principles of biopotential measurement, including the origin of these signals within living tissue, the design of electronic systems to record them, and the use of software to process and analyse the recorded signals for medical diagnosis, physiological monitoring and other practical applications.

• Bioslam circuit build and submit proof.

• Electrical circuits quiz

• Origin of biopotentials quiz

• Written assignment? Probably not.

• Some kind of measurement task / experiment / system (medical / communication)

• What is a biopotential?

• Unipolar and bipolar leads.

• Electrocardiogram (ECG)

• Electroencephalogram (EEG)

• Electromyogram (EMG)

• Electrooculogram (EOG)

• Electrical safety

• Ohm's law in lumped and volume contexts

• Excitable cells - neurons and myocytes

• Action potentials

• Instrumentation amplifier

• Active electrodes

• Driven right leg

• Biopotential electrodes

• Digitising biopotential signals - sampling frequency and resolution

• Signal processing for biopotentials - filtering, artefact detection and removal

• Sources of interference - exogenic / endogenic, differential and common mode
