Abstract :
The accepted models of the origin of interference in body surface potential recordings predict that it would be advantageous to perform signal amplification on the electrode. A suitable circuit for a miniature biopotential amplifier to be manufactured in thick-film technology is described. A prototype series of active electrodes was produced and tested. The high immunity to interference resulted in ECG and EEG recordings of a very high quality
