Abstract

최근 개개인 건강에 대한 관심이 증가하고 사물인터넷이 발달함에 따라 웨어러블 헬스케어 분야 시장이 급속도로 성장하고 있다. 특히 인체에서 발생하는 신호를 실시간으로 감지하고 모니터링 할 수 있는 웨어러블 센서의 중요도가 늘어나고 있으며 특히 맥박에 의한 혈관 변화처럼 미세한 인체의 변형 신호나 체온, 외부의 온도 등에 의해 발생하는 신호를 감지할 수 있는 고감도 스트레인 센서와 온도 센서에 대한 관심이 증가하고 있다. 하지만 현재 사용되고 있는 웨어러블 센서들은 몇 가지의 한계점을 가지고 있으며 상용화되기에 부족한 문제가 있었다. 본고에서는 이와 같은 기존 웨어러블 센서의 문제를 해결할 수 있는 소재로 각광받고 있는 나노 입자 기반 웨어러블 센서에 대하여 다루고자 한다. 나노 입자를 사용한 웨어러블센서는 간단한 방법으로 고감도를 확보할 수 있고 용액 공정을 통해 저가로 생산이 가능하기 때문에 웨어러블 센서 소재로서 적합하다. 여기서는 나노 입자의 기본적 특성과 나노 입자 기반 스트레인 센서 및 온도 센서 동향을 소개한다. 차세대 헬스케어 분야의 선두 주자가 되기 위해서는 나노 소재를 기반으로 한 웨어러블 센서의 개발과 연구가 중요하다.
