| Research Abstract |
To investigate the factors that influence tongue volume, morphological features and the volume of the tongue and mandible in Japanese males were measured with Computed tomography (CT) data. The subjects were 40 Japanese males (Age : 52.6±12.5 years, Body Mass Index : 25.4±3.4 kg/m2). With all subjects, the tongue and mandible volume ( mean±SD ) were 78,990±10,607.8 mm3 and 87,806±12,079.6 mm3, respectively. The mean of T/M ratio would be important to determine the position and range of motion of the tongue was 91%. After measurement tongue volume, two-way sinuous actuator using air pressure and nylon strings was applied to fabricate the artificial tongue. Arrangement and interference of the each actuate were also verified so that artificial tongue can perform appropriate the form and position change. The curvaceous and rhythmical movements like a real tongue can be done by the prototype model without interference. Alternatively, self-moving artificial tongue was developed to achieve the swallowing without any power sources.
