Soft pressure sensor using multi-material 3D-printed microchannel molds and method for making the sensor

Abstract

The present invention relates to a flexible pressure sensor using a multi-material 3D-printed microchannel mold, and a method for manufacturing the same. An object of the present invention is to provide a flexible pressure sensor using a multi-material 3D-printed microchannel mold, the flexible pressure sensor being formed by using a conductive liquid and an elastomer, having a microchannel formed therein, and having improved flexibility, sensitivity, and stability in comparison to the related art. Another object of the present invention is to provide a method for manufacturing a flexible pressure sensor using a multi-material 3D-printed microchannel mold, in which the flexible pressure sensor is manufactured by using the microchannel mold including microbumps, the microchannel mold being multi-material 3D-printed by using a sacrificial material and a hard material.
