플렉서블/웨어러블 일렉트로닉스

기계적 유연성이 부여되어 인체에 부착해 컴퓨팅이 가능한 모든 종류의 전기/전자 소자

Carbon Electronics?

탄소에 존재하는 pi-오피탈의 전자를 전하이동 매개체로 이용하는 반도체를 의미합니다. 미래플렉서블 일렉트로닉스에 매우 적합한 고유연성, 고전도성 등 우수한 전기전자 특성을 가지고 있습니다.
: 유기물 반도체 (저분자, 고분자), 탄소나노튜브, 그래핀 등

Flexible Electronics 시장 추이

세계 플렉서블 일렉트로닉스 시장은 '20년부터 연평균 7.9% 성장하여 '25년에는 420억 달러 규모로 TV시장과 비슷한 규모로 성장할 전망임
