Outline of Final Research Achievements |
Insects are minimum flyers in the animal kingdom, of which representative dimensions are on the order of 1mm. Hence, it is expected that artificial flyers line drones can be minimized by mimicking insects. However, because of complexity of phenomena and limitation of fabrication, the insect-mimetic flyer on the order of 1mm has not been realized. In this study, (1) the strongly coupled multiphysics and multisystem analysis method was developed, (2) the 2.5-dimensional structure of MEMS was designed such that it can present flapping functions using the insect flight mechanism, and (3) the design solutions were fabricated using the MEMS micromachining process. It follows from these results that the possibility of the insect-mimetic flyer on the order of 1mm was demonstrated.
