Abstract
The present invention is related to a flexible substrate structure for microneedle arrays and its manufacturing method, whose structure mainly comprising: tapered shape objects and flexible substrate. Wherein, structure of the tapered shape object is composed of a tip, sidewalls, and a base. Meanwhile, the flexible substrate winds tightly around sidewalls of tapered shape objects and is set up on, yet covers the base surface of tapered shape object which faces the tip of tapered shape object. Because the structure applies a flexible substrate along with tapered shape objects, hence, the fit-to-body capability is increased and allows thereof more appropriate for backside drug delivery, as well as sufficiently bring the characteristic of large-area manufacturing into full play.
