Abstract—A noncontact ECG measurement scheme has many advantages over a conventional ECG measurement system. But, one of the main problems of noncontact ECG signal is its susceptibility to power line disturbances, caused by powered electronic equipments or power line wires. In this paper, a scheme for non-contact ECG measurement was first developed and its sensitivity to power line interference got suppressed using a novel signal conditioning method. After designing the suitable capacitive electrodes, the signal from the active electrodes are amplified, filtered and finally displayed in a Virtual Instrument developed in a LabVIEW environment. The simulation of the overall scheme for the suppression of power frequency disturbance has been carried out and the result shows a significant improvement in the SNR.
