An electrocardiogram is one of general ways to screen for heart disease. It is lower-invasive and does not need expensive facility. The conventional electrocardiogram is measured by only twelve electrodes. It is minimum number of the electrodes to screen for heart and is not enough to precise diagnose. For the precise electrical potential distribution measurements, an electrocardiogram mapping method employing many electrodes is investigated.Precise information about the heart can be measured by many electrodes on the chest. However, the installation of them is complicated and invasive to a subject.In this study, an electrode array sheet which can be attached to the chest by vacuum fabricated and the electrocardiogram mapping measurement is attempted. The time for the measurement is shortened and the measurement become easier. Using the electrode array sheet in the chest is measured mental stress.
