Abstract

본 연구에서는 silver nanowire (AgNW)를 polydimethylsiloxane (PDMS) 기판에 embedding하여 손가락 움직임을 전기 신호로 읽을 수 있는 투명 저항식 변형 센서를 제작하였다. 이후 bluetooth를 이용한 무선 통신의 방식으로 변형 센서가 내는 데이터를 컴퓨터와 스마트폰 앱으로 전송하는 근거리 통신을 가능하게 하였다. 최종적으로 데이터 가공공정을 통하여 스마트폰 앱으로 변형 센서에 의한 손가락 움직임을 읽고 이미지를 변환시키는 프로그램을 제작하여 컴퓨터와 스마트폰 앱으로 확인하였다.
In this study, we fabricated transparent resistive strain sensor by embedding silver nanowire in polydimethylsiloxane (PDMS) substrate to sense the finger bending motion electrically. Using bluetooth as wireless data transfer system, strain data was transferred to computer and smart phone application enabling near field communication. Additionally, we made a program translating resistance change by finger motion strain to save images and confirmed that it worked at application and computer.
