Biomedical Electronics

Biomedical signal acquisition: conditioning of bioelectric and other signals; signal isolation, preamplifiers; noise sources and measures to limit their contribution to signal contamination; small signal acquisition; instrumentation amplifiers; active and passive filters; frequency bands of typical biomedical signals; filtering of biomedical signals; pulse and waveform generators for electrical stimulation of tissues.

Biomedical instrumentation for signal acquisition: ECG, EMG, EEG. Electrical stimulation of excitable tissues, heart pacemakers, cardioverters, defibrillators, functional electrical stimulation. Electrosurgical devices. Electromagnetic compatibility and safety of electrical medical devices (sources of danger (electrical hazards), safety measures, leakage currents, safety-related markings on equipment, safety testing, safety and other standards).

To learn about specific electronic circuits and elements typically encountered in medical instruments used in clinical and research environment. To gain practical experience from using the instruments and from building and testing a biopotential amplifier or electrical stimulator or some other device.

To build awareness of the need for safe design, operation and use of biomedical devices from the patient's and the operator's point of view. To gain elementary knowledge about standards and measures needed to protect against electrical hazards in medical environment.

Lectures, individual practical lab assignments, one major project assignment (planning, designing, building and evaluation of a biopotential amplifier or some other device to acquire a specific biomedical signal), self

study. This course should be taken together with the course Measurements and Sensors in Biomedicine (both courses run in parallel and share some of the lab work and the project).
