摘要：
A micro-needle device is applicable for a target tissue with a first area having a first parameter and a second area having a second parameter. The micro-needle device includes a substrate and a micro-needle array connected to the substrate. The micro-needle array includes a first micro-needle corresponding to the first area and a second micro-needle corresponding to the second area. One of the surfaces of the substrate having the micro-needle array corresponds to the surface curvature of the target tissue. The first micro-needle has a first configuration corresponding to the first parameter, and the second micro-needle has a second configuration corresponding to the second parameter and different from the first configuration. The configuration includes at least one selected from a group consisting of length, distribution density, diameter, and medicine-carrying amount of micro-needle. A method for manufacturing a micro-needle device and a method for manufacturing a micro-needle mold are also provided.
