Biomedical Instrumentation will focus on Biomedical Sensors, Measurements and Instrumentation to detect electrical and non-electrical parameters in the human body. The course will start with an introduction to sensors, principles of sensing, types of sensors. Then the course will focus on Biopotentials, their origin and faithful measurement. Examples from ECG, EMG, EEG and other ExG will be discussed in sufficient depth and detail. Then we move on the GSR, PCG. Then the focus will be on non-electrical parameter measurements such as blood pressure, temperature, volume and flow, respiratory measurement (Sphygmomanometer), cardiac output. Then the focus will shift to Ventilator,Cardiac Pacemaker, Defibrillator, hemodialyser. The final topics will be on safety, standards and regulations in medical devices.

Intended audience: UG and PG students in Biomedical Engg, Instrumentation Engg and electrical engg.

Prerequisites: Basic Electrical Engg, Basic principles of sensing, measurement and transduction
