Disclosed are a pressure sensor for sensing pressure in a vertical direction, a strain sensor for sensing tension in a horizontal direction, and a method for manufacturing the sensors. The disclosed pressure sensor includes a plurality of pressure sensor units stacked in multiple layers, and at least one of a pressure elastic modulus and an amount of conductive particles per unit area of each of the plurality of pressure sensor units is different from each other.

Pressure sensor for sensing pressure in vertical direction, strain sensor for sensing tension in horizontal direction, and method for manufacturing sensors

A pressure sensor having unevenness and a manufacturing method therefor are disclosed. The disclosed pressure sensor senses pressure in a vertical direction and includes a first pressure sensor unit and a second pressure sensor unit, wherein the first pressure sensor unit and the second pressure sensor unit are stacked, and unevenness is formed on the upper surface of the first pressure sensor unit and on the lower surface of the second pressure sensor unit.

Pressure sensor having unevenness and manufacturing method therefor

A continuous electric/electronic device and a method of manufacturing the same are disclosed. The method of manufacturing a continuous electric/electronic device having a serial connection structure comprises (a) disposing a first electrode current collection unit, (b) disposing first organic&#x22c5;inorganic material in regard to the first electrode current collection unit, (c) laminating a first area of a second electrode current collection unit on the disposed first organic&#x22c5;inorganic material, (d) disposing second organic&#x22c5;inorganic material in regard to a second area of the second electrode current collection unit and (e) laminating a third electrode current collection unit on the disposed second organic&#x22c5;inorganic material. Here, the first area and the second area of the second electrode current collection unit operate as current collection units having different polarity in regard to adjoining first organic&#x22c5;inorganic material and second organic&#x22c5;inorganic material.

Electric/electronic device and manufacturing method thereof

A method of manufacturing nano-fiber non-woven fabrics is provided. The method comprises preparing a polyurethane solution by dissolving polyurethane in an organic solvent, producing an electrospinning solution by adding far infrared ray emitting particles, antibacterial inorganic particles, and deodorization inorganic particles to the polyurethane solution, and electrospinning the electrospinning solution to form the nano-fiber non-woven fabric. The far infrared ray emitting particles may be obtained by adding a metal oxide to ceramics and sintering the metal oxide-added ceramics. The antibacterial inorganic particles may be obtained by impregnating a zirconium-based carrier with silver ions. The deodorization inorganic particles may be obtained by impregnating a zirconium-based or a silica oxide-based carrier with an amine-based compound.
