A precise 3D CAD model of mosquito central labrum and side maxillae, i.e., totally three needles, was constructed. Mosquito inserts these needles inside the human skin with vibration. To confirm the effect of vibration, explicit FEM analysis was conducted using the model. LS-DYNA was adopted as the software. In this report, only the central needle was preliminarily considered among the three, and this needle was inserted into the skin in the simulation. It is proven that the resistance force was reduced by 6.5 % at the maximum with applying vibration. Next, Stress applied to a skin was visualized using an artificial skin with grid pattern. The visualizing test result also indicated that stress applied to skin by inserting needle is reduced by applying vibration. The simulation and image analysis results indicates the effect of vibration on easy needle insertion without buckling.
