Abstract: Disclosed are a skin-attachable adhesive patch mimicking a leg structure of a diving beetle and having excellent skin-attachment ability even in a dry or wet condition, and a method for manufacturing the same. The skin-attachable adhesive patch includes a substrate; a plurality of negative pressure chambers formed on a surface of the substrate, wherein each of the plurality of negative pressure chambers has a truncated hollow sphere structure; a micro-wrinkle layer formed on at least a portion of a remaining area of the substrate except for an area thereof where the negative pressure chambers are formed; and a patterned carbon particle layer formed on the micro-wrinkle layer.

Abstract: The present invention relates to a fiber composite for a strain sensor and a method for producing the same. The composite includes a stretchable fiber; a conductive elastic polymer layer coated on the stretchable fiber; polymer beads disposed on the stretchable fiber or on the elastic polymer layer; and a conductive elastic polymer layer covering the polymer beads. The fiber composite is durable and stable. Therefore, a strain sensor produced using the fiber composite exhibits excellent durability, recoverability, repeatability and sensitivity, and a fast sensing speed.

Abstract: Disclose is a dry adhesive patch comprising: a plurality of embossed pillars formed on a substrate; a hemi-spherical adsorbing cup defining a top portion of each pillar, wherein a hemi-spherical hole is defined in a top portion of the adsorbing cup and is exposed to an outside; and an annular extension extending radially from an outer perimeter of a distal end of each adsorbing cup.

Abstract: The present invention relates to an adhesive patch. The adhesive patch includes a plurality of reliefs, each relief having a flat top face, and each micro channel groove defined between adjacent reliefs of the plurality of reliefs, wherein the plurality of reliefs and the micro channel groove are respectively formed on and defined the adhesive patch, and wherein a hydrogel layer is disposed on at least a portion of a bottom face of the micro channel groove and is contained in the groove. Therefore, the adhesive patch is well-adhered to a dry or wet adhered face.
