摘要: This paper reports the measurement of properties dry or pasteless conductive electrodes to be used for long-term recording human electrocardiogram (ECG). Knowledge these is essential correct design input stage associated amplifiers. Measurements were made on seven commercially available carbon based at pressures 5 mmHg (0.67 kPa) and 20 (2.7 kPa), located lower abdomen chest body subjects having different skin types. Parameter values fitted a two-time- constant model electrode using data measured over period 10 s. Values resistance, ranging from 23 kΩ 1850 capacitance 0.01 μF 65 obtained components, while time-constants varied 0.02 s 7.2
