<p>There is a need for minimally invasive medical needles that can reduce the pain during insertion. However, to develop such a fine needle, it is necessary to evaluate the resistance force during needle insertion. In this study, we conducted an experiment to puncture microneedle into artificial skin and a nonlinear finite element method analysis using LS-DYNA, and evaluated the resistance force when microneedles were punctured into a model imitating artificial skin. At this time, the analysis result was directly compared with the experimental result by conducting analysis under conditions reproducing material physical properties of artificial skin, needle shape, diameter, puncture speed and the like used for puncture experiment.</p>
