Simulation and Analysis of Microneedle for Drug Delivery based on Structural and Fluid Flow Mechanics

MEMS (Micro Electro Mechanical System) design systems are used for the development of microneedles, which are used for drug delivery. The drug delivery through micronnedle is painless which is not in case of transdermal needles. In this paper the simulation and analysis of microneedle is presented. The typical structure of a microneedle is simulated for studies of the structural behavior of microneedle and the fluid mechanics of the drug delivery. The studies show that the microneedle with silicon material can withstand the physical conditions also drugs of various viscosities with various velocities can be delivered successfully.
