| Outline of Final Research Achievements |
We fabricated triaxial force sensor applicable to non-invasive human lingual motion measurement. The sensor contains two cantilevers for shear force sensing and one beam for pressure sensing. These cantilevers and the beam were buried in the silicone rubber. Their hinges are consisting of piezo-resistive layers in order to detect the force applied on the silicone rubber surface. Water swallowing experiment was conducted and we measured the pressure and shear forces acting on palate. From the experiment, we quantified the ease of consumption of the viscosity-increased water compared to the normal water.
