| Research Abstract |
Mosquito proboscis consists of plural needles, among which central straight labrum and side jagged maxillae, i.e., three needles, play important role of inserting the proboscis into the skin. A model of these three needles motion is constructed theoretically. Using this model, it is elucidated that a negative stiffness model is realized in the labrum insertion, which eases its insertion with even small driving force near zero. Finite element method (FEM) simulation and insertion experiments using three bundled micromachined needles imitating mosquito labrum and maxillae were conducted, the results of which indicates the validity of proposed model.
