The electrode material used in ECG is generally
Answer: A
ECG electrodes are generally made of silver-silver chloride.
An Ag/AgCl electrode is nearly non-polarisable: charge crosses the interface freely through the reversible reaction between silver and silver chloride. This gives a low, stable half-cell potential, low noise and little motion artefact, which is why disposable ECG electrodes use an Ag/AgCl sensor with chloride gel.
Platinum is a polarisable metal whose half-cell potential drifts, so it is used more for stimulation and some implanted electrodes. Copper and nickel corrode, are noisy and can irritate the skin.
