Biomedical instrumentation BM8502 


UNIT -1

     BIOPOTENTIAL ELECTRODES

Syballus:

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.
