METHOD AND/OR APPARATUS FOR PUNCTURING A SURFACE FOR EXTRACTION, IN SITU ANALYSIS, AND/OR SUBSTANCE DELIVERY USING MICRONEEDLES

摘要

A method and apparatus for puncturing a surface for etraction, in situ monitoring, and/or substance delivery uses microneedles with improved properties. Applications include easy to handle glucose monitoring using a group of hollow out-of-plane silicon microneedles to sample substances in interstitial fluid from the epidermal skin layer.
