    摘要: Embodiments are directed to microneedle array devices for intradermal and/or transdermal interaction with the body of patient to provide therapeutic, diagnostic or preventative treatment wherein portions of the devices may be formed by multi-layer, multi-material electrochemical fabrication methods and wherein individual microneedles may include valve elements or other elements for controlling interaction (e.g. fluid flow). In some embodiments needles are retractable and extendable from a surface of the device. In some embodiments, interaction occurs automatically with movement across the skin of the patient while in other embodiments interaction is controlled by an operator (e.g. doctor, nurse, technician, or patient).
