Pressure sensor

A pressure sensor comprising:

• a base material;
• a first through-hole and a second through-hole formed on one surface of the base material, the first through-hole and the second through-hole being formed through the base material so as to extend from an upper surface to a lower surface thereof;
• and
• a conductive thread sensor, the conductive thread sensor comprising a first signal line extending from one side of the base material, a sensing portion extending from the first signal line so as to continuously extend from the one surface of the base material via the first through-hole and the second through-hole, the sensing portion being coupled to the first through-hole and the second through-hole, and a second signal line extending from the sensing portion so as to extend to the other side of the base material.

A pressure sensor comprising:

• a base material;
• a plurality of through-holes formed on one surface of the base material, the plurality of through-holes being formed through the base material so as to extend from an upper surface to a lower surface thereof;
• and
• a conductive thread sensor, the conductive thread sensor comprising a first signal line extending from one side of the base material, a sensing portion extending from the first signal line so as to continuously extend from the one surface of the base material via the plurality of through-holes, the sensing portion being coupled to the plurality of through-holes, and a second signal line extending from the sensing portion so as to extend to the other side of the base material.

A pressure sensor comprising:

• a base material;
• a through-hole formed on one surface of the base material, the through-hole being formed through the base material so as to extend from an upper surface to a lower surface thereof;
• a first signal line extending from one side of the base material and a first electrode portion extending from the first signal line so as to extend through the through-hole from the one surface of the base material and to be coupled to one side of an inner circumferential surface of the through-hole;
• a second signal line extending from the other side of the base material and a second electrode portion extending from the second signal line so as to extend through the through-hole from the one surface of the base material and to be coupled to the other side of the inner circumferential surface of the through-hole, the second electrode portion being spaced apart from the first electrode portion while facing the first electrode portion;
• and
• a dielectric substance, with which a space between the first electrode portion and the second electrode portion is filled.
