| Popis: | This paper provides values of the electrical elements of equivalent models for several textile-based electrodes. In ECG recording the skin-electrode-amplifier interface is modelled as an equivalent electrical circuit having one or two parallel C-R networks and series resistance. The electrical properties have been established using a switched dc current source, modulated with a sinusoidal source. For the single C-R electrode model values of resistance ranged from 10 kΩ to 28 MΩ and of capacitance from 0.03 nF to 15 μF. In the double C-R model values of resistance ranged from 1 kΩ to 25 MΩ and of capacitance from 9 pF to 872 μF. Recording of the ECG using textile-based electrodes has recently been explored in the context of wearable technology for telemedicine and remote monitoring. Knowledge of the electrical properties of such electrodes is essential for the design of amplifiers in ECG monitors to meet the IEC 60601 requirements. |
