Abstract: A sensor includes a base material and a through-hole formed to pass through the upper surface and the lower surface of the base material. The sensor may also include a conductive thread sensor including conductive thread that passes through the through-hole. The pressure sensor is implemented through a structural combination of the conductive thread and the base material so that the degree of design freedom can be effectively increased in the application of a variety of recent wearable flexible materials.

Abstract: A conductive yarn pressure sensor is proposed. The pressure sensor may include a porous fiber layer having predetermined cavities formed therein. The pressure sensor may also include a first sensing electrode made of a first conductive yarn formed on one surface of the porous fiber layer, and a second sensing electrode made of a second conductive yarn formed on the other surface of the porous fiber layer. The first sensing electrode or the second sensing electrode may be provided so as to be in contact with each other in the cavities of the porous fiber layer due to external pressure. According to an embodiment, by having conductive yarn in flexible clothing or textile material, pressure can be sensed by effectively responding to deformation due to external pressure.
