Outline of Final Research Achievements

Regarding plant specimens, the outer shape, vein and surface texture structure were finely transferred onto the metal plate. The feathers of birds can be confirmed visually by single fiber on the metal plate, however, little change can be confirmed by touch.Regardless of the material of the original mold, the shockwave molded replica by overlapping leaves or origami structure like origami transcribes its internal three-dimensional structure. In this case, it is difficult to grasp the structure even by visual sense. Copper and aluminum are suitable as museum specimen presuming exhibits that can be touched by unspecified people. By scanning electron microscopy, transcription was confirmed in almost all cell walls and about 68% of the cell wall surface structure.
