  Abstract

Much research has been carried out to combine textiles and electronic products. However, most of the studies use conductive metal yarn, and the resultant fabric is not flexible enough to use as clothing. In addition, the circuits that connect textiles to electronics are not flexible. Therefore, the aim of this study was to induce conductivity in textiles using screen printing to directly print conductive ink on substrates and then develop a heart rate measurement band using them. To accomplish this, the printing conditions were first optimized by the amount of ink and amount of printing to increase conductivity. Then, the circuit was designed to be operated via a Lilypad Arduino and printed using screen printing. Finally, a heart-rate band that can be visually identified by an LED blinking according to the heart rate was created.
