Apparatus and method for manufacturing an intracutaneous microneedle array

Abstract

A microneedle array is constructed of silicon and silicon dioxide compounds using MEMS (i.e., Micro-Electro-Mechanical-Systems) technology and standard microfabrication techniques. The microneedle array may be fabricated from a silicon die which can be etched in a microfabrication process to create hollow cylindrical individual microneedles. The resulting array of microneedles can penetrate with a small pressure through the stratum corneum of skin (including skin of animals, reptiles, or other creatures—typically skin of a living organism) to either deliver drugs or to facilitate interstitial fluid sampling through the hollow microneedles.
