Research Abstract

Stretchable conductive inks composed of an acrylic- and a polyurethane-based elastomer containing Ag flakes were developed for smart textile (E-textile) applications. Although variation in electrical resistivity depending on the binder chemistry was apparently observed, the conductive inks exhibited very low electrical resistivities of 20-200 ・・cm when they were cured at 80-100 ℃. The electrical resistance of the printed wires increased with increasing elongation. An insulative ink was also prepared to be used for cover layers of wires made of the conductive inks. Stretchable circuits were formed using the electrically conductive and insulative inks on fabrics by the additive printing method. Electrocardiograms (ECG) were successfully monitored using the printed wires as leads from human bodies during normal activities of daily life.
