The e-Textile is the key technology for continuous ambient health monitoring to increase quality of life of patients with chronic diseases. The authors introduce techniques of Japanese historical textile, NISHIJIN, which illustrate almost any pattern from one continuous yarn within the machine weaving process, which is suitable for mixed flow production. Thus, NISHIJIN is suitable for e-Textile production, which requires rapid prototyping and mass production of very complicated patterns. The authors prototyped and evaluated a few vests to take twelve-lead electrocardiogram. The result tells that the prototypes obtains electrocardiogram, which is good enough for diagnosis.

The authors are developing e-textile measuring 12-lead ECG signal based using a historical brocade developing technique, NISHIJIN-ORI. In this paper, a NISHIJIN e-textile sensor belt prototype designed for ambulatory measurement (pre-hospital 12-lead ECG measurement) was tested on twenty volunteers. The recorded data was evaluated through the result of commercial automatic ECG analyzer. The obtained results are almost equivalent with the ones obtained through conventional ECG electrodes. However, the results suggest slight modification of the prototype.
