There are many researchs have explored the geometric design and fabrication of microneedle array, but fewer explore inserting destruct. In the dynamically penetrating simulation, the basic geometry of the octagon, hexagon, taper , and pyramid could be obtained by using finite element software ANSYS in this study. The results showed that pyramidal microneedle array are the best design of penetrating.The hollow microneedle array is fabricated successfully by contacting exposure with three-dimensional mask. It is found that the geometry of the fabricated microneedle array are affected by square metal aperture stop and the altitude of photoresist. When the photoresist coating thickness is higher, the bottom corner will be more close to predict.
