Abstract According to the present invention, a soft sensor using three dimensional printing uses a syringe to three dimensionally print a conductive liquid metal on a first flexible layer to form a micro channel without being affected by limitations on sizes and shapes. Also, since a mold is not used, a soft sensor thinner than a case where a mold is used can be manufactured. Also, since the syringe is used to three dimensionally print the conductive liquid metal, the thickness of the micro channel can be minimized. Also, since the micro channel formed between the first flexible layer and a second flexible layer is made of the conductive liquid metal to maintain a liquid state, flexibility of the micro channel can be secured. Also, since a channel pattern is designed by using CAD/CAM, the channel pattern can be easily designed and modified. 본 발명에 따른 3D 프린팅을 이용한 소프트 센서는, 제1신축성 층 위에 전도성 액체 금속을 주사기를 이용해 3D 프린팅함으로써, 크기나 형상에 제약을 받지 않고 마이크로 채널을 형성할 수 있다. 또한, 몰드를 이용하지 않기 때문에 몰드를 사용하는 경우보다 얇은 두께의 소프트 센서를 제조할 수 있다. 또한, 전도성 액체 금속을 주사기를 이용해 3D 프린팅하기 때문에, 마이크로 채널의 두께가 최소화될 수 있다. 또한, 제1신축성 층과 제2신축성 층 사이에 형성된 마이크로 채널은 전도성 액체 금속으로 형성되어, 액체 상태를 유지하기 때문에 마이크로 채널의 신축성이 확보될 수 있다. 또한, CAD/CAM을 이용하여 채널 패턴을 설계하기 때문에, 채널 패턴의 설계 및 수정이 용이한 이점이 있다.
