Syllabus BM8502 BIOMEDICAL INSTRUMENTATION  OBJECTIVES: The students will be exposed to electrical and non-electrical physiological measurements and  bioamplifiers. UNIT I BIO POTENTIAL ELECTRODES   Origin of bio potential and its propagation. Electrode-electrolyte interface, electrode–skin interface, half  cell potential, Contact impedance, polarization effects of electrode – non polarizable electrodes. Types of  electrodes - surface, needle and micro electrodes and their equivalent circuits. Recording problems – motion artifacts, measurement with two electrodes. UNIT II BIOPOTENTIAL MEASUREMENTS   Biosignals characteristics – frequency and amplitude ranges. ECG – Einthoven’s triangle, standard  lead system, Principle of vector cardiography, EEG – 10-20 electrode system, unipolar, bipolar and  average mode.EMG– unipolar and bipolar mode, Recording of ERG, EOG and EGG. UNIT III SIGNAL CONDITIONING CIRCUITS  Need for bio-amplifier - single ended bio-amplif...
