인쇄전자(printed electronics) 기술은 인쇄(graphic art printing)가 가능한 기능성전자 잉크소재를 이용하여 초저가격의 프린팅 공정을 통해서 다양한 전자소자를 제작하는 기술로서, 차세대 모바일 IT 기기의 제작에 적합한 전자제품을 생산하는 데 적합한 공정 기술로 인식되고 있다. 현재 기술 수준이 일부 요소 부품을 제작하는 수준에 머무르고 있으나, 여러 가지 잉크소재 및 다양한 초미세 인쇄공정 기술의 개발이 진행됨에 따라 향후 다양한 공정 분야에 적용될 것으로 예상되며, 궁긍적으로 전자제품을 생산하는 기존 반도체 공정을 대체하는 공정으로 자리매김을 할 것으로 예상된다. 특히 인쇄공정 기술은 저온에서 공정이 가능한 기능성 잉크소재들의 개발을 통해서 유연한 플라스틱 기판에 전자소자를 제작하는 플렉시블 전자소자(flexible electronics) 기술과 높은 공정 결합성을 지니고 있으며 이들 공정을 결합하여 향후 연속 공정(roll-to-roll)의 구현이 가능할 것으로 예상된다. 본 기고문에서는 이러한 인쇄전자 기술의 개발동향에 대해서 기술하였다.
