3D Pressure sensor and manufacturing method of pressure sensor using 3D printing

摘要

An embodiment of the present invention, as a 3D printing method, a first step of outputting an electrical signal transmission unit on a base substrate, washable to cover a portion of the electrical signal transmission unit in a region where a plurality of pressure cells are to be formed on the base substrate A second step of outputting a layer, a third step of outputting a plurality of pressure cells having a second engaging portion having a shape corresponding to the first engaging portion on the washable layer while outputting a first engaging portion on the base substrate , And a fourth step of removing the washable layer, provides a pressure sensor manufacturing method using 3D printing and a pressure sensor manufactured accordingly, and various pressure cells can be combined to measure various ranges of pressure.
