Flexible pressure sensor using multi-material 3D-printed microchannel mold and method for manufacturing the same다중물질 3차원 프린팅을 통해 제작한 마이크로채널 몰드를 이용한 유연압력센서 및 그 제작방법
The present invention relates to a flexible pressure sensor using a multi-material 3D-printed microchannel mold, and a method for manufacturing the same, and more particularly, to a flexible pressure sensor having improved flexibility, sensitivity, and stability for use in a wearable device, and a method for manufacturing the same. Further, the present invention relates to a physical sensor for measuring a force applied from the outside, and more particularly, to a multi-directional physical sensor using a multi-layer microchannel array, which may sense all forces applied from the outside in three-dimensional directions such as a perpendicular direction and a parallel direction by applying the multi-layer microchannel array to a body having a three-dimensionally protruding shape.
