Mimosa pudica, commonly called as sensitive plant, folds quickly its leaflets in response to an external stimulus. In order to obtain any innovative ideas for artificial structures, we measured the geometry of sensitive plant leaves and observed their folding motion. Numerical simulation using leaf model based on the optical measurement was also perfumed. It was found that the total kinetic energy of leaflets for fully unfolding increased with the increase of vein angle and aspect ratio of leaflet. However, the bending stress of vein at the fixed end dramatically decreased with increasing the aspect ratio
