Performance Evaluation of Biomedical ECG Suction Electrodes with Different Materials

A suction electrode is often used as a precordial electrode in clinical electrocardiograms. It can be used frequently and has no need for adhesive or a strap. Higher source impedance since the contact area is small. The present study aims to 1) design and implement biomedical suction electrodes with different types of materials (Copper and Aluminum) and determine the dimensions of each electrode, 2) apply these constructed electrodes on subjects in hospitals and laboratories to extract their electrocardiogram waveform, and 3) finally, make a comparison between these constructed electrodes (Copper and Aluminum) with the standard electrode made from Ag/AgCl. The results obtained indicate that the best material for a construction electrode after the Ag/AgCl material is the Copper material, which gives the same electrocardiogram signal with high efficiency and accuracy. In addition, Copper material is less expensive than silver, so it is desired to use it in the reading of electrocardiogram signals. While Aluminum material was never used in the electrode construction, this was obtained from the reading of its electrocardiogram signal
