Abstract: A manufacturing device for a microneedle includes an upper plate stage, a lower plate stage disposed in horizontally parallel with the upper plate stage, a rotating device configured to rotate and move the upper plate stage over the lower plate stage, and a first cylindrical type actuator configured to vertically move the lower plate stage in a state in which the upper plate stage has been rotated and moved over the lower plate stage by the rotating device. The first cylindrical type actuator may upwardly and downwardly move so as to be able to stretch a viscous composition in a vertical direction in a state in which a contacting to the viscous composition is performed, wherein the viscous composition is applied on both of a patch sheet seated on the upper plate stage and a patch sheet seated on the lower plate stage, or is applied on one of them.

Abstract: The present disclosure relates to a microneedle array for bio-sensing or a biosensor using the microneedle array. The microneedle array for bio-sensing does not include an additional electrode or an additional conductive coating, have a solid structure, and is homogeneous throughout the solid structure. The microneedle array for bio-sensing is composed of a material including poly (3,4-ethylendeddioxythiophene):poly (styrenesulfonate) (PEDOT:PSS).

Abstract: A manufacturing method of a microstructure includes providing a patch manufacturing sheet formed in a state in which a bottom layer is exposed on an upper part thereof; providing the patch manufacturing sheet on a first process substrate and a second process substrate; spotting a viscous composition at a plurality of positions spaced apart from each other on the bottom layer of the patch manufacturing sheet provided on only the first process substrate, or provided on both of the first process substrate and the second process substrate; contacting the patch manufacturing sheet provided on the second process substrate or the viscous composition to the viscous composition spotted on the patch manufacturing sheet provided on the first process substrate; moving relatively the second process substrate with respect to the first process substrate to stretch the viscous composition and to coagulate the stretched viscous composition; and cutting the coagulated viscous composition.
