Biomedical Electronics

The specifics of small-signal acquisition, including the instrumentation amplifiers, will be introduced. Topics of bioelectric signal conditioning, signal isolation, preamplifiers, sources of noise and measures to limit the impact of various sources of interference on the signals will be covered. Typical biomedical signals will be specified in terms of their origin, frequency and amplitude ranges and other characteristics. Instrumentation for acquisition of electrophysiological signals (ECG, EMG, EEG), electrical stimulation of excitable tissues (e.g. pacemakers, cardioverters, defibrillators) and other devices (e.g. electrosurgical device) will be presented. A significant attention will be paid to safety aspects of electromedical devices (properties and safety measures in design and use of these devices, labeling and testing of medical devices and safety standards) and certification of medical devices

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).
