릴리패드 아두이노를 이용한 스크린 프린팅 기반의 심박수 밴드 개발

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 flexibleenough to use as clothing. In addition, the circuits that connect textiles to electronicsare not flexible. Therefore, the aim of this study was to induce conductivity in textiles usingscreen printing to directly print conductive ink on substrates and then develop a heart ratemeasurement band using them. To accomplish this, the printing conditions were first optimizedby the amount of ink and amount of printing to increase conductivity. Then, the circuitwas 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 theheart rate was created.
