A prototype series of active electrodes manufactured in thick-film technology demonstrated high immunity to interference, resulting in very high quality ECG and EEG recordings.
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.
MettingVanRijn et al. (Tue,) conducted a other in Biopotential recordings (ECG and EEG). Low-cost active electrode was evaluated on Immunity to interference and recording quality. A prototype series of active electrodes manufactured in thick-film technology demonstrated high immunity to interference, resulting in very high quality ECG and EEG recordings.
