Multi-layered fabric electrode for movement artifact reduction in capacitive ECG measurement

An electrode configuration composed of multi-layered fabric electrodes were examined and compared with that composed of non-layered fabric electrodes in terms of movement artifact reduction when using the electrodes in capacitive electrocardiogram measurement from human buttocks in a vibrating environment. Experiments performed with six participants revealed that the multi-layered configuration composed of sensing electrode, driven shield and ground layers reduced amplitude of movement artifact significantly than the non-layered configuration.
