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.
