Pressure sensor using conductive thread and method of manufacturing the same

A method of manufacturing a pressure sensor using conductive thread, the method comprising:

• preparing a plurality of first conductive lines and a plurality of second conductive lines;
• preparing a spacer having a plurality of pressure areas formed therein, the spacer being configured such that resistance of the spacer is changed when pressure is applied thereto;
• disposing the plurality of first conductive lines so as to be spaced apart from each other in a state of being parallel to each other in a first direction, disposing the plurality of second conductive lines so as to be spaced apart from each other in a state of being parallel to each other in a second direction intersecting the first direction, and coupling the first conductive lines and the second conductive lines to the spacer such that the spacer is disposed between the first conductive lines and the second conductive lines;
• and
• connecting a first electrode to one end of a first conductive line of the plurality of first conductive lines, connecting a second electrode to one end of a second conductive line of the plurality of second conductive lines, and coupling a cover sheet configured to cover an area in which the electrodes are connected to each other,
• wherein preparing the spacer comprises forming resistors in resistance areas each formed in a cross area in which the first conductive lines and the second conductive lines intersect each other, and
• wherein forming the resistors comprises:
• allowing a solution comprising a first concentration of the resistors to permeate a portion of the cross area to form a first concentration of a first resistance area of the resistance areas;
• and
• allowing a solution comprising a second concentration of the resistors to permeate another portion of the cross area to form a second concentration of a second resistance area of the resistance areas.
