Abstract

In this study, we investigated the feasibility of using printed Indium Tin Oxide (ITO) film as a remote sensor for Hazardous and Noxious Substances (HNS). To improve the quality of the ITO films, binder mixing ratio, Sn concentration in ITO, thermal treatment temperature, and printing process conditions were optimized. We fabricated an electrical resistance-type liquid sensor, and to confirm the sensor operation, the change in resistance in air and seawater was monitored. The change in resistance of the ITO sensor was explained in terms of reduction reaction on the surface. Further, the sensor was controlled by Arduino, and the remote data acquisition was demonstrated.

본 연구에서는 Indium-Tin-Oxide 인쇄 박막의 원격 검출이 가능한 해양오염 방제용 센서로서의 응용 가능성에 대해 연구하였다. 우선 양질의 박막제작을 위한 바인더 비율, Indium-Tin-Oxide 중 주석 농도, 열처리 온도 등의 Indium-Tin-Oxide 인쇄박막 제작 조건을 최적화시켰다. 이를 이용하여 전기저항형 액체 센서를 제작하였고, 센서 동작을 확인하기 위하여 대기 중과 해수 중에서 저항 변화를 확인하였다. 이때 저항 변화의 원인은 전해질 속에서 표면에서 일어나는 환원반응에 의한 것으로 해석하였다. 또한 제작된 센서를 Arduino를 사용하여 작동시키고 취득한 데이터의 원격 검출이 가능함을 확인하였다.
