Abstract:
We investigated a system by which an electrocardiogram can be obtained without the individual's awareness. The practice of this concept involves placing the electrodes in a bed set composed of electrically conductive textiles. Electrocardiograms were successfully obtained during sleep. However, during the periods of subject's movement in bed, the waveform became unrecognizable.
