Abstract

When biopotentials are recorded from the surface of the skin, the skin impedance will usually influence the measurement. Surface electrodes are widely used in the measurement of bioelectric events, such as ECG, EEG or EMG. We minimized the skin impedance by improving the blood circulation. The skin impedance may be reduced maximally by more than 50% after soaking in warm water for 5 minutes. This method can be applied in all the measurement used surface electrodes so as to obtain high resolution, especially achieving better results for patients with bad blood circulation.
